How often should you check your portfolio

TL;DR — Checking every day feels responsible. It is not. Daily checking leads to daily decisions, and daily decisions lead to worse outcomes. Monthly is enough for a quick sanity check. Quarterly is enough for actual rebalancing. The exception is big macro events, where checking makes sense. Otherwise, close the app.

There is a counterintuitive truth about portfolio management: the less you look, within reason, the better your results tend to be.

This is not about being lazy. It is about understanding what actually moves in the market versus what is just noise.

Day-to-day, markets move constantly for reasons that have nothing to do with the underlying thesis of your investments. A comment from a central banker. A slightly disappointing jobs number. A geopolitical rumor. Your energy ETF drops 2 percent. Your gold position drops 1.5 percent. None of this means your thesis is broken. It is noise. But if you are checking every day, you will feel like you need to respond. You will make decisions based on noise. Those decisions will cost you money over time.

Here is a practical cadence.

Monthly (about 10 minutes). Look at allocation only. Is any position more than 5 percent above or below its target weight? If no, close the app. If yes, note it for the quarterly review. Check that your protection layer is roughly intact. Done.

Quarterly (about one hour). This is the real review. Go through each position: has the macro regime changed? Is any position significantly above or below target? Does any new capital need to be deployed? Is any thesis broken? Make all your rebalancing decisions here. Outside of this review, the default answer to "should I do something?" is almost always no.

When big macro events happen. There is a category of events that legitimately warrants checking outside the schedule: a central bank making an unexpected major policy reversal, a country going into a currency crisis, a geopolitical event large enough to change the macro regime of a country you hold. These are rare. Not every headline qualifies. A month of bad PMI data does not. A country defaulting on its debt does. Use your judgment, but keep the bar high.

The most important discipline is separating "the price moved" from "something actually changed." Prices move every single day. Something in the underlying macro regime actually changing happens a few times per year at most.

Example — During the COVID crash of March 2020, investors who checked their portfolios every day made an average of more than 10 significant portfolio decisions in six weeks. Most of those decisions were panic-driven and locked in losses. Investors who stuck to a quarterly review held through the bottom and fully participated in the recovery that followed. Same portfolio. Radically different outcomes. The difference was how often they looked.

Monthly glance. Quarterly review. Everything else is noise.
