On Checking Your Portfolio
Why checking less often leads to better decisions.
On Checking Your Portfolio
Key Takeaways
- Portfolio checking triggers dopamine like a slot machine. The uncertainty of gains or losses activates your brain’s reward system, making it addictive
- Checking daily exposes you to “loss days” 25% of the time versus just 12% for quarterly checkers, doubling emotional pain for zero strategic benefit
- Missing the 10 best market days over 20 years cuts returns roughly in half, and those days almost always happen during crashes when compulsive checkers panic sell
The Dopamine Loop
The best investors check their portfolios rarely. The most anxious ones check constantly. There’s an inverse relationship worth understanding.
Every time you open that app, you’re essentially pulling a slot machine lever. The market moves randomly. You don’t know if your balance will be up or down. That uncertainty triggers a dopamine release. Your nervous system doesn’t care that you’re checking a spreadsheet. It cares that something unpredictable is happening, and unpredictability is thrilling to your ancient brain.
The problem: that dopamine spike is strongest when you’re losing money. Your brain treats losses as urgent. So checking becomes most addictive during the exact times you should check least.
The Math That Matters
With roughly 250 trading days a year and a 10% expected annual return, you’re actually more likely to see a small loss on any given day than a small gain.
Someone who checks quarterly sees the same overall returns but only encounters loss days about 12% of the time. Someone checking daily sees them about 25%. That’s double the emotional pain for no strategic benefit whatsoever.
Here’s what really matters: missing just the 10 best market days over 20 years cuts your returns roughly in half. Those best days almost always happen during crashes, when your portfolio is underwater and you’re feeling the pain. What do portfolio checkers do during crashes? They watch their balance plummet, they panic, and right when recovery is about to happen, they sell. They exit at exactly the worst moment.
This happened in March 2020. People who checked constantly got out of the market. Then they watched the most dramatic recovery in years happen without them. Their caution cost them more than any crash ever could.
Breaking the Habit
The nuclear option: delete the app. This feels radical, but it works. Your phone is designed for frictionless access. When you delete the app, checking requires logging in on your computer. That added friction is enough for your conscious brain to intervene before the automatic habit takes over. Most people who do this simply stop checking. It’s not willpower. It’s friction breaking the compulsive loop.
If you can’t go that far, try scheduling. Put it on your calendar, first Friday of the month, maybe. Make checking scheduled and intentional. Your brain stops searching for the reward because you know exactly when it’s coming. The compulsion drops significantly.
Habits don’t disappear; they transform. When you stop checking, there’s a void. Fill it with something else: pushups, water, meditation, step outside, text a friend. It doesn’t matter what. It just needs to give you a quick reward that isn’t checking your portfolio.
When Checking Is the Symptom, Not the Problem
If you truly cannot stop checking, that might not be a checking problem. It might be a portfolio problem.
Your tolerance for volatility might not match what you’re invested in. If a 10% market correction keeps you up at night and checking obsessively, you’re probably overexposed. Adjust to something you can actually sleep with. A 40/60 stock-and-bond portfolio rarely moves enough to trigger that dopamine loop. When you rebalance to match your actual tolerance, the problem often solves itself.
Goal-Based Tracking
Some investors take a more sophisticated approach. They don’t set alerts for price movements. They set alerts for actual goals. Only notify yourself if you fall significantly behind on retirement or college savings. Remove the checking compulsion because there’s nothing to obsessively monitor. You’ll get alerts for things that truly matter.
The Core Insight
Discipline alone won’t work. The right tools and the right friction will. Pick one approach and commit to it for a month. Most people find they simply stop wanting to check once the loop is broken.
Your checking habit isn’t a character flaw. It’s your brain’s reward system colliding with technology designed to trigger dopamine. You can work with that. You don’t need heroic willpower. You need the right structure.
When you check less, you panic less. When you panic less, you make better decisions. You don’t exit at bottoms or chase at tops. You stay on course. That discipline, compounded over decades, is how wealth actually builds.
Gallio is built with this philosophy in mind: web-only, deliberately, so there’s friction between you and your portfolio. That friction isn’t a limitation. It’s the entire point.
