Who Else Wants to Invest Just 15 Minutes a Year and Never Have to Watch the Stock Market Again?
It's 2:14 in the morning. The house is dark. And you're lying in bed with your phone two inches from your face, refreshing your portfolio for the ninth time since dinner.
Red. Still red. A little more red than an hour ago.
If you've ever lost money in the stock market, you know that feeling in your stomach. And here's the cruel joke nobody tells you: all that watching doesn't protect your money. It quietly drains it.
Set and forget investing is the cure. You make every big decision once (what to own, how much to put in, and when), you automate it, and then you check on it just once a year. Done properly, the whole job takes about 15 minutes a year. And the research says the less you fiddle, the more you tend to keep.
This guide shows you exactly how to set it up, the 15-minute checkup you do once a year, and what to do (and not do) when the market falls apart.
Short answer Set and forget investing means building a simple, low-cost, diversified portfolio, putting your monthly investing on autopilot, keeping a cash buffer so you never have to sell in a crash, and then checking in just once a year to rebalance. It works because the biggest danger to most people's returns isn't the market. It's their own reactions to it. |
In this guide:
What Is Set and Forget Investing?
Set and forget investing is a hands-off way to invest where you do the thinking up front, then take your hands off the wheel.
You pick a small number of low-cost, broadly diversified funds. You decide how much goes in every month. You tell your bank and your broker to do it automatically. Then you leave it alone, except for one short checkup a year.
That's it. No stock tips. No daily news. No "should I sell?" panic at 2 a.m.
Some people call it "set it and forget it investing," "hands-off investing" or "lazy investing." The name doesn't matter. The idea does: you design a system that works even when your emotions don't.
What it is NOT
Set and forget does not mean "never look again for 30 years."
Critics say set and forget investing doesn't work any more because people live longer and markets change. They have a point about the "never look" version. Life changes. Your mix needs to change as you get older. Fees creep up. Beneficiaries need updating.
That's exactly why the checkup exists. A better name might be "set and check once a year." You don't ignore your money. You just stop staring at it.
| Set and forget investor | Hands-on investor | |
How often they act | Once a year, on a set date | Whenever the news is scary or exciting |
What they own | A few cheap, broad index funds | Hot stocks, tips, sector bets, "the next big thing" |
How money goes in | Automatically, every month | When they "feel" the time is right |
What a crash means | A normal event the plan already expects | An emergency that demands action |
Time spent | About 15 minutes a year | Hours a week |
Why Watching the Market Makes You Poorer
This sounds backwards. Surely paying close attention to your money is the responsible thing to do?
In most of life, yes. In investing, the evidence says no.
The experiment that proved more information can cost you money
In 1997, four of the most famous names in behavioral economics (Richard Thaler, Amos Tversky, Daniel Kahneman and Alan Schwartz) ran an experiment published in the Quarterly Journal of Economics.
They let people invest in a mix of a risky fund and a safe fund, and gave some of them feedback on their results often, and others only rarely.
The result? The investors who got the most frequent feedback took the least risk and earned the least money.
Think about that. The people with the most information did the worst.
The reason has a name: myopic loss aversion. "Loss aversion" means a loss hurts us more than an equal gain pleases us. "Myopic" means short-sighted. Put them together and you get a person who checks too often, sees too many little losses, feels too much pain, and gets scared out of the very investments that grow wealth over time.
Behavioral economist Shlomo Benartzi of UCLA explained it simply: the more often you check the stock market, the more likely you are to see that it has gone down. In the short run, the market falls often. Over decades, it has risen. When you look every day, you live in the scary short term. When you look once a year, you live in the hopeful long term.
The hidden "behavior tax" on ordinary investors
Every year, the research firm Morningstar measures something called the investor return gap. It compares what funds earned with what the people who owned those funds actually earned, after all their buying and selling.
In its 2026 report, covering the 10 years to December 2025 and about 23,000 US funds and ETFs, Morningstar found:
The average fund earned 9.9% a year.
The average dollar invested in those funds earned only 8.7% a year.
That's a gap of about 1.2 percentage points a year, roughly 12% of the total return, or about $3.8 trillion over the decade.
Morningstar is careful to say the gap isn't only caused by bad timing; even sensible habits like adding money every month can create a small gap. But look at which investors had the smallest gaps:
People in US stock index funds lost just 0.1 points a year. People in allocation funds, the "all-in-one" type that includes target-date funds, lost 0.7 points. People in actively managed funds lost 1.6 points.
In other words: the more "set and forget" the investment, the more of its return people actually kept.
What 1.2 points a year really costs you
"1.2%" sounds small. It isn't. Here's what it does to $100,000 left alone for 20 years:
At the fund's 9.9% a year, $100,000 grows to about $660,600. At the average investor's 8.7%, it grows to about $530,400.
That's roughly $130,000 lost, not to a market crash, not to a bad company, but to buying and selling at the wrong times. Over 25 years, the same gap grows to more than $250,000.
That's the price of watching. (If you'd like to see this gap year by year, I break it down in the hidden gap that left ordinary investors behind the market.)
The Market Pays You for Sitting Still: The "Best Days" Problem
Here's the trap that catches almost every investor who tries to "get out before it gets worse."
The market's best days and worst days arrive together, often in the same scary weeks.
J.P. Morgan Asset Management studied what happened to $10,000 invested in the S&P 500 from January 2005 to the end of 2024:
Stayed invested the whole time: $71,750, about 10.4% a year.
Missed just the 10 best days: $32,871, about 6.1% a year.
Missed the 60 best days: $4,712, a loss of about 3.7% a year, over a 20-year stretch in which simply staying put turned $10,000 into more than $70,000.
And here's the killer detail: seven of the 10 best days happened within two weeks of one of the 10 worst days.
So the person who sells after a terrible day, "just until things calm down," very often misses the huge rebound days that come right after. They lock in the loss and miss the recovery.
A set and forget investor doesn't have this problem. They're never out of the market, so they never miss the best days. Their system makes them sit still in exactly the moments their gut screams "run."
If you've ever sold near a bottom, please don't beat yourself up. It's one of the most human things in the world, and I explain why smart people do it in why hard-working people sell at the very bottom. The fix isn't more willpower. The fix is a system.
Proof From the Top: What Warren Buffett Told His Wife's Trustee
Warren Buffett is probably the most famous stock picker who ever lived. So what does he want done with the money he leaves his own wife?
In his 2013 letter to Berkshire Hathaway shareholders, he spelled it out. His advice to the trustee: put 10% in short-term government bonds and 90% in a very low-cost S&P 500 index fund. He even suggested Vanguard's.
No stock picking. No market timing. No clever trades. Just two boring funds, left alone.
He believed this simple policy would beat most investors, including pension funds and institutions, who pay high-fee managers.
Notice the 10% in short-term government bonds. That's not there to earn big returns. It's a buffer, so that in a crash, there's safe money to live on and nobody is forced to sell stocks at the bottom. We'll copy that idea in a moment.
The $1 million bet that proved it
Buffett didn't just talk. Starting on January 1, 2008, he bet $1 million that a simple S&P 500 index fund would beat a group of hedge funds hand-picked by professionals over 10 years.
By the end of 2016, with one year to go, the index fund had compounded at 7.1% a year. The five funds-of-hedge-funds averaged just 2.2% a year. The other side conceded, and Buffett's winnings went to Girls Inc. of Omaha.
The boring fund that nobody touched beat the experts who were paid millions to be clever. (I tell the full story in Warren Buffett's famous $1 million bet.)
And it's not a one-off. S&P Dow Jones Indices found that 79% of actively managed large-cap US funds trailed the S&P 500 in 2025 alone.
Proof From the Bottom: The Janitor Who Just Kept Holding
Ronald Read pumped gas for about 25 years and then worked as a part-time janitor for another 17, in and around Brattleboro, Vermont. He lived quietly and frugally. Nobody knew he had money.
When he died in 2014 at age 92, his estate was worth almost $8 million. He left about $4.8 million to the local hospital and $1.2 million to the town library.
How? According to The Wall Street Journal, he owned at least 95 stocks when he died, many of which he had held for years, even decades. His first recorded purchase was in 1959. The Journal credited his "remarkable frugality and patience."
Now, Read picked individual stocks, and I'm not suggesting you do. Most people who try lose to the index. But the lesson of his life is pure set and forget: he bought solid businesses, he kept buying, and he held on for decades. His holding years ran straight through the 1970s slump, the 1987 crash, the dot-com bust and 2008. Time did the rest.
The famous "dead investors" story (and the truth about it)
You may have heard that Fidelity once studied its customers and found its best-performing accounts belonged to people who were dead or had forgotten they had an account.
It's a great story. Unfortunately, when Morningstar's John Rekenthaler checked with his contact at Fidelity, they had never heard of it. Nobody has ever produced the original. It appears to be investing folklore.
But Rekenthaler made a fair point anyway: the "study" rings true whether it exists or not. A forgotten account can't panic, can't chase tips and can't sell at the bottom. You don't have to die to invest like a dead person. You just have to build a system that doesn't need you.
The 4-Part Set and Forget System
Here's the whole system. You'll set it up once, in an afternoon. After that, it runs without you.
Part 1: Pick a simple, all-weather core
What you "set" matters more than anything. You can only safely forget something that's built to be forgotten. A single hot stock, a crypto coin or a high-fee fund your bank sold you is not.
You want three things: broad diversification (hundreds or thousands of companies), low fees (ideally well under 0.25% a year) and simplicity (one to three funds).
Here are the three most common set and forget setups:
Setup | What you own | Best for | Upkeep |
One-fund (target-date or all-in-one fund) | A single fund holding stocks and bonds, which slowly gets safer as you age | People who want zero decisions | Almost none: the fund rebalances itself |
Buffett-style (90/10 or your own split) | An S&P 500 index fund plus short-term government bonds or cash | People happy to own mostly US large companies | Rebalance once a year |
Two- or three-fund | A global stock index fund plus a bond fund (some add a home-country fund) | People who want worldwide diversification | Rebalance once a year |
The one-fund option is the most "forgettable" of all. Vanguard's latest How America Saves report found that people who held a single target-date fund were four to five times less likely to trade than other retirement savers. In 2025, only 1% of them changed their investments at all.
How much in stocks versus bonds? A common rule of thumb is: the shorter your time horizon and the more a crash would frighten you, the more bonds and cash you want. The right mix is the one you can actually hold through a 40% fall without selling.
Want help choosing? Read the lazy 3-fund portfolio, how many index funds you really need, and, if you live outside the US, how to pick one fund for life.
Part 2: Put the money on autopilot
This is where most "set and forget" plans quietly fail. People set up a monthly transfer into their brokerage account... and the money just sits there as cash, because they never told it to buy anything.
Automate the whole chain:
Payday transfer. Have money move from your bank to your investment account automatically, the day after you get paid. If it never sits in your checking account, you won't miss it.
Automatic buying. Turn on "auto-invest" or a recurring purchase so the cash is invested into your chosen funds straight away. In a workplace plan such as a 401(k), your contributions are already invested for you.
Dividend reinvestment. Switch on automatic reinvestment, or choose "accumulating" funds that reinvest for you.
Automatic increases. If your plan offers "auto-escalation," let it raise your contribution by 1% a year. You'll barely feel it.
Investing the same amount every month also means you automatically buy more shares when prices are low and fewer when they're high. (If you're restarting after a big loss, lump sum or monthly walks you through that choice.)
To see what steady monthly investing can grow into, look at what $500 a month in an S&P 500 index fund becomes after 10, 20 and 30 years.
Part 3: Build your "panic buffer"
This is the part most guides leave out, and it's the part that saves people.
Most investors don't sell in a crash because they're foolish. They sell because they need the money (a job loss, a medical bill, a new roof) and the only money they have is in falling stocks.
So keep two things outside the stock market:
An emergency fund of several months of living costs in a high-interest savings account. If you're retired or close to it, many planners suggest more.
Any money you'll need within about five years (a down payment on a house, a child's college costs, your first years of retirement spending) in cash, short-term government bonds or similar safe holdings. Not in stocks.
That's the job of Buffett's 10% in short-term bonds. When the crash comes, and it will, you'll have safe money to live on. You'll never be forced to sell at the bottom. That single fact makes "forget" possible.
Part 4: Lock the door on yourself
Now protect the system from its biggest threat: you, on a bad day.
Delete the trading app from your phone, or at least move it off your home screen. You can still log in from a computer once a year.
Turn off price alerts and market news notifications. Benartzi's advice to investors was simple: curate your digital world so you aren't flooded with feedback you don't need.
Write a one-page "rules letter" to your future self. Example:
“I invest [amount] every month into [fund or funds], with [X]% in stocks and [Y]% in bonds and cash. I only make changes on my checkup day each year, or if my life changes. I do not sell because of the news.”
Pick your checkup date now and put it in your calendar as a repeating yearly event. Your birthday or the first week of January works well.
The 15-Minute Annual Checkup
Once a year, on your chosen date, you sit down with a cup of coffee and do this. That's the whole job.
No. 1: Is the money still going in? (3 minutes)
Open your account. Check that every monthly transfer happened and was actually invested, not left as cash. If you got a raise this year, consider nudging your monthly amount up.
No. 2: Check your mix. (3 minutes)
Look at what percentage is in stocks and what percentage is in bonds and cash. Compare it to the target in your rules letter.
No. 3: Rebalance, but only if you're more than 5 points off. (4 minutes)
If your mix has drifted more than 5 percentage points from target, move it back. If it's within 5 points, do nothing.
Why 5 points and why once a year? Vanguard tested this. It found that for most diversified stock and bond portfolios, checking once or twice a year and rebalancing only at about 5% thresholds strikes a reasonable balance between controlling risk and keeping costs down. In its earlier study of 1926 to 2009, rebalancing every month meant 1,008 trades; checking once a year with a 10% threshold needed just 15.
Here's a worked example. Your target is 60% stocks and 40% bonds on a $200,000 portfolio. After a strong year for stocks, you have:
| Target | Now | Action | |
Stocks | 60% = $120,000 | 68% = $136,000 | Sell $16,000 of stocks |
Bonds | 40% = $80,000 | 32% = $64,000 | Buy $16,000 of bonds |
You're 8 points off, so you rebalance. Tip: if you're adding money every month, you can often fix the drift without selling anything, simply by pointing new contributions at whatever is underweight for a few months. That can also avoid taxes in a taxable account.
If you hold a target-date or all-in-one fund, the fund does this step for you. Skip it.
No. 4: Check your fees. (2 minutes)
Look up the yearly fee (the "expense ratio") on each fund and any account or adviser fees. A fee that looks tiny can quietly eat a huge slice of your retirement. Here's how a "tiny" 1% fee can steal a quarter of your retirement.
No. 5: Has your life changed? Update the plan. (3 minutes)
Married, divorced, a new grandchild, retiring within five years, a big expense coming? Update your mix, your cash buffer and your beneficiaries. If retirement is coming close, it's time to read up on a safe withdrawal plan such as the 4% rule.
Then close the app for 12 months.
Do the math on the time you get back. Checking your portfolio for just 5 minutes a day adds up to about 30 hours a year, or more than 600 hours over 20 years. The set and forget investor spends about 5 hours in those same 20 years, and probably earns more.
What to Do When the Market Crashes
It will happen. Probably several times while you own your funds. The S&P 500 has had corrections and crashes again and again, and set and forget investors sit through every one of them.
When the headlines turn red, follow this:
Notice how almost every path ends in "do nothing." That's not laziness. That's the plan working.
If a crash does tempt you, remember three things:
Your panic buffer is doing its job. You don't need to sell anything to pay your bills.
The best days hide right next to the worst ones. Selling now is how people miss them.
History is on your side, though nothing is guaranteed. See whether the S&P 500 has ever lost money over 20 years.

7 Mistakes That Turn "Set and Forget" Into "Set and Regret"
Mistake No. 1: Setting the wrong thing. Putting your money into a handful of stocks, a sector fund or an expensive bank-sold fund, then "forgetting" it. Forgetting only works on something broad, cheap and built to last.
Mistake No. 2: Choosing a mix you can't sleep with. If 100% stocks would make you sell in a 40% crash, it's the wrong mix, however good it looks on paper.
Mistake No. 3: Never rebalancing. Over many years, a portfolio left completely alone drifts towards more and more stocks, which means more risk just when you may need less.
Mistake No. 4: Ignoring fees. A 1% fee is not small. Over decades it can take a huge share of your money.
Mistake No. 5: Leaving cash uninvested. Your transfer is automatic, but nothing is buying. Years later you discover a pile of cash earning almost nothing.
Mistake No. 6: Forgetting your life, not just your portfolio. Old beneficiaries, a retirement date that's now close, or new family members all need a plan update. If you live outside the US and own US-listed funds, also check the US estate tax trap that can hit non-residents.
Mistake No. 7: "Just a quick look." One peek becomes a daily habit, and the daily habit brings back the fear. If you must look, look at your yearly progress, never the daily change.
Is Set and Forget Investing Right for You?
It's probably a great fit if you:
Are investing for goals five or more years away, such as retirement
Have lost money before by trading, chasing tips or panic selling
Have a job, a family, a business or a life, and don't want to spend it watching charts
Want a plan you can explain in one sentence
You may need more help (or a fee-only adviser) if you:
Need regular income from your portfolio right now and aren't sure how much you can safely take
Have a complicated tax situation, a business to sell or an inheritance to plan
Know you'll panic in a crash no matter what, even with a buffer
For most people, the answer is simple: the less exciting your investing is, the better it tends to work. As Jack Bogle, founder of Vanguard, liked to say in his own way, don't just do something, stand there. (Here are Bogle's 10 rules for investors who are tired of losing money.)
Your "Tonight" Plan: Set It Up in One Evening
You don't need to wait for the "right time." Here's what to do tonight:
Write down your target mix (for example, 70% stocks and 30% bonds and cash) and the one to three funds you'll use.
Check your emergency fund. If it's thin, build it before you invest more.
Set up the payday transfer and the automatic purchase. Make sure the money is actually invested.
Turn on dividend reinvestment and switch off price alerts.
Write your rules letter and put your yearly checkup date in your calendar.
Then go and do something you enjoy. You've just done more for your future wealth than a year of watching the market ever could.
Frequently Asked Questions
What is set and forget investing?
Set and forget investing is a hands-off strategy where you choose a few low-cost, diversified funds, automate your monthly investing and dividend reinvestment, keep a cash buffer for emergencies, and then check your portfolio only about once a year to rebalance. The aim is to stop your emotions from hurting your returns.
Does set and forget investing really work?
The evidence strongly supports it. Morningstar's 2026 Mind the Gap study found investors in simple, automatic funds lost far less to bad timing than others: just 0.1 points a year in US stock index funds versus 1.6 points in actively managed funds. Staying invested also means you never miss the market's best days.
How often should I check my investments?
For most long-term investors, once a year is enough, plus whenever your life changes in a big way. Vanguard's research found checking once or twice a year and rebalancing only when your mix is about 5 percentage points off target gives a sensible balance between controlling risk and keeping costs low.
What is the best set and forget investment?
There is no single best one, but the most hands-off choice for many people is a low-cost target-date or all-in-one fund, which holds stocks and bonds and rebalances itself. Others prefer a broad index fund, such as a global or S&P 500 fund, combined with a bond fund and rebalanced yearly.
Should I sell when the market crashes?
Usually not. J.P. Morgan found seven of the 10 best market days between 2005 and 2024 came within two weeks of one of the 10 worst. Selling in a crash often means missing the rebound. Keep money you need within five years out of stocks so you're never forced to sell.
Is set and forget investing good for retirees?
Yes, with two changes. Retirees usually need a bigger cash and bond buffer to cover several years of spending, and they need a withdrawal plan. The yearly checkup becomes the moment to refill the cash buffer from whichever part of the portfolio has grown, rather than selling stocks in a downturn.
Do I need a financial adviser for set and forget investing?
Many people set it up themselves with a target-date fund or a simple two- or three-fund portfolio. If your situation is complex (large savings, business income, tax or estate questions), a fee-only adviser who doesn't earn commissions can help you design the plan once, so you can then leave it alone.
The Most Profitable Thing You'll Ever Do Is Nothing
The market will crash again. The news will scream again. Your neighbor will brag about a stock that went up 300% (and won't mention the three that went to zero).
None of that has to touch you any more.
Build the system once. Feed it every month. Protect it with a cash buffer. Give it 15 minutes a year. Then go and live your life, and let time do what time does best.
If you've lost money in the stock market before, I want you to know something: it probably wasn't your fault. You were never shown how the game really works.
