Why You Should Probably Stop Checking Your Portfolio
The plain answer
Section titled “The plain answer”Checking your portfolio every day makes ordinary volatility feel like an emergency. The account did not need you. The habit did.
A calendar reminder each quarter, plus a check after a real life change, is enough for most long-term plans.
How it actually works
Section titled “How it actually works”Markets produce a new number constantly. Most of those numbers cancel out over years. Your brain does not average them. It weights the last red day.
More checking also creates more chances to tinker: a new fund, a “temporary” cash position, a sale you will reverse next week. Each trade can add tax and fees.
Automation (payroll contributions, dividend reinvestment if you want it) does the useful work without a login.
What this means for you
Section titled “What this means for you”Delete the brokerage app from the home screen, or log out after you confirm contributions are running. Put one review on the calendar. During that review, compare the mix to your IPS and rebalance if the rules say so.
If you cannot stop checking, that is information. Your allocation may be too aggressive for sleep, or you are using the account as entertainment. Both are fixable without day-to-day trading.
Common mistakes
Section titled “Common mistakes”Checking more often after a drop, which is when the worst trades happen.
