Why weekly
Most portfolio tools are built to be checked constantly: a live ticker, a push notification, a red or green number that updates while you watch it. That's not an accident. Engagement is the business model for most of them. It's also, for most people, a bad way to relate to money you're not planning to touch for years.
Checking a long-term portfolio every hour doesn't make you better informed. It mostly just shows you noise. A stock moving 2% intraday and a stock moving 2% over a real week mean very different things, but a live dashboard presents them identically: as a number, right now, demanding a reaction. Drift is built on the opposite premise, that the useful signal in a portfolio shows up on a weekly timescale, and that a calmer cadence produces a clearer picture, not a worse one.
What weekly actually buys you
A week is long enough for a real move to separate itself from ordinary noise, and short enough that nothing important goes unnoticed for long. It's also just enough distance to describe what happened in plain language instead of reacting to it in real time, which is the whole reason Drift writes a narrative instead of just showing you a chart.
Depth instead of frequency
Once you stop optimizing for how often someone checks, you can spend that attention differently: on depth instead of frequency. That's why Drift computes an actual correlation matrix instead of a pie chart (a portfolio can look diversified by ticker count and still move like two or three stocks), and why every portfolio gets a specific, named archetype. Not a generic score, but an actual description of the pattern your holdings currently form, and why. Real-time tools don't have room for this kind of thing; a number that has to update every second doesn't have space to explain itself.
A promise, not a disclaimer
Drift will never tell you what to buy, sell, or hold. Not as a legal hedge buried in a footer, but as an actual design constraint on what the product is for. Every digest describes what's already true about your portfolio: what happened, what it means, how concentrated or diversified it actually is. What you do with that is entirely yours. A tool that's trying to keep you calm has no business also trying to tell you what to do next.
If daily check-ins genuinely work better for how you think about money, that's available too. It's an explicit choice you make, not the default you have to opt out of.
