Status quo bias is the tendency to prefer things the way they already are. We stick with the current situation, or the default option, even when a change would serve us better, because changing feels like a decision and staying put does not. The term comes from a 1988 paper by economists William Samuelson and Richard Zeckhauser, who found that people “disproportionately stick with the status quo”.
In investing and trading, it looks like this. You hold a position long after the reason you bought it has gone. You leave a portfolio drifting instead of rebalancing it. You keep using a strategy that stopped working because reviewing it feels like admitting something.
The fix starts with one idea: doing nothing is still a decision. Below is why the bias is so strong, how it shows up in a trading account, and 3 ways to flip the default.
What did the research on status quo bias find?
Samuelson and Zeckhauser ran a series of decision experiments and then looked at real choices. In their words, data on the health plans and retirement programmes picked by university staff showed that “the status quo bias is substantial in important real decisions.” People did not re-choose each year. They kept what they had.
Defaults are even more powerful. Rolf Dobelli, in The Art of Thinking Clearly, describes an experiment by Eric Johnson and Dan Goldstein on organ donation. When people had to opt in, about 40% agreed. When donation was the default and they had to opt out, take-up rose to more than 80%. The question was the same. Only the starting point changed.
Dobelli adds the line that matters most for traders. Even when nobody sets a default for us, “we make our past the default setting, thereby prolonging and sanctifying the status quo.”
Why do we stick with the status quo?
The deepest reason is loss aversion. Daniel Kahneman, in Thinking, Fast and Slow, calls it “a powerful conservative force that favors minimal changes from the status quo in the lives of both institutions and individuals.” A change means giving something up, and the pain of what we give up looms larger than the pleasure of what we might gain.
There are 2 more forces at work. One is regret. If you change something and it goes wrong, it feels like your fault. If you leave it and it goes wrong, it feels like bad luck. The other is effort. Reviewing a position or a plan takes energy, and doing nothing takes none.
| What it feels like | What is really happening |
| “I’m just being patient.” | holding because selling would mean admitting a loss |
| “Nothing has changed.” | the reason for the trade has changed, but the position has not |
| “I’ll deal with it later.” | the default is being left to make the decision |
| “It’s always worked before.” | the past has become the default setting |
These overlap with a few close cousins: loss aversion, the endowment effect, which makes what we own feel more valuable, and regret aversion. Status quo bias is where they meet: the pull to leave everything as it is.
How does status quo bias show up in trading?
Here is the most expensive example I know, because it is mine.
In June 2026 I was up about 7.5% for the year, with a book concentrated in one theme. A hot jobs report on a Friday gapped the whole thing, and within 2 sessions the year’s gain was nearly back to flat, at about +0.5%. My trading plan had a rule to trim exactly that kind of concentration. I knew the rule. I did not fire it.
In my journal that night I called it a discipline lapse, not a strategy failure. But the lapse had a shape. Trimming was an action, so it felt like a decision. Holding felt like nothing at all. Doing nothing was the default, and the default won.
Then it got worse. About 10 days later, I built the same concentration straight back up. That is status quo bias in its purest form. Failing to change is one thing. Drifting back to the old setting once the pain fades is worse.
Imagine your own version. Say a position you bought on a clear reason is now down, and that reason no longer holds. You know you would never buy it today. Yet selling feels like a choice with consequences, while holding feels like waiting. Most traders who freeze in that moment are not being stubborn. They are being human, and the default is doing their thinking for them.

How do you overcome status quo bias?
You do not overcome it by trying harder. Willpower fails at exactly the moment you need it, because that is when the loss is fresh and the fear is loudest. What works is changing which option is the default. Here are 3 ways to flip the default.
- The blank-slate test. For each position, ask: if I had this money in cash today, would I buy this, at this price, for this reason? If the answer is no, holding is a fresh decision to buy it again, and it deserves the same scrutiny as any new trade.
- Make rules objects, not intentions. On the same day that my trim rule failed, I drank a protein shake I had made the night before without a second thought. The difference was form. The shake was a physical object in the fridge, and the rule was a sentence in a document. So the fix is to turn rules into things that act on their own, such as a standing order on the position or a calendar block that says “cut exposure”.
- Set a review date. A position, a portfolio or a strategy with no scheduled review will be reviewed only when something goes wrong. A date in the calendar makes the review the default, and doing nothing becomes the option you have to choose on purpose.
A trading plan and a trading journal are where these live. The plan holds the rules, and the journal shows you when you skipped them.
Is sticking with the status quo ever the right call?
Yes, often. Most of good trading is waiting, and a trader who changes the plan after every losing week is making the opposite mistake. Holding a position because the reason for it still stands is a decision, and a good one.
The bias is not holding. The bias is holding without deciding. The blank-slate test catches the difference: a position you would happily buy again today is one you are holding on purpose.
Personally, I think the most useful thing I ever learnt about defaults happened before I traded at all. During an accounting internship at a Big Four firm, I saw the path everyone expected me to take, felt in my gut that it was not mine, and walked away from it towards markets. Leaving a default is hard because it is a decision. Staying in one is easy because it never feels like one.
That Friday in June did not cost me because I lacked a rule. It cost me because the rule needed me to act, and doing nothing was easier. For more on the biases that sit beside this one, see conservatism bias, herd mentality in trading, the narrative fallacy, and the full trading psychology guide.
FAQ
What is status quo bias?
It is the tendency to prefer the current situation or the default option, even when a change would be better. The term comes from a 1988 paper by William Samuelson and Richard Zeckhauser.
What is an example of status quo bias in investing?
Holding a stock after the reason you bought it has gone, simply because selling feels like a decision and holding does not. Leaving a portfolio unbalanced for years is another.
What causes status quo bias?
Mainly loss aversion, the fact that losses feel bigger than equal gains. Fear of regret and the effort of reviewing a decision add to it.
How is status quo bias different from the endowment effect?
The endowment effect makes things we own feel more valuable. Status quo bias is a wider pull towards leaving any situation as it is, whether or not we own anything.
How can traders overcome status quo bias?
Change the default instead of relying on willpower. Ask whether you would buy each position today, turn rules into standing orders or calendar blocks, and schedule regular reviews.
