Document why you believe in a stock, track the evidence over time, and know when your original thesis changes.
Company facts from SEC filings. Your reasoning stays yours — and stays on the record.
AI infrastructure spending will continue driving data center growth faster than the market expects, and the software attach rate makes that growth stickier than a hardware cycle.

Illustrative figures. In the product every number is drawn from a filing and links to its source.
You bought for one reason. Three months later the stock is down and you are certain you bought for another. The story updates itself quietly, and the lesson disappears with it.
“Margins should expand as the new product mix scales.”
“Margins compressed. Mix shifted toward lower-margin hardware.”
“I was mostly buying for the long-term AI story anyway.”
The Decision Ledger remembers for you.
Every thesis, target, catalyst, risk and invalidation rule is timestamped. You can change your mind. You cannot quietly rewrite what you used to think.
Record why the stock deserves your attention, in your own words. StockMemo will not write it for you — the argument has to be yours.
Choose the metrics, catalysts, risks and invalidation conditions the thesis depends on. Make it falsifiable while you still believe it.
See whether reported results support or weaken your case, then record what you concluded and why.
When you change a thesis, conviction, catalyst, risk, price assumption or time horizon, StockMemo writes a new version and keeps the old one exactly as you left it — with the reason you gave at the time.
Over a few years that becomes the most useful document you own: a record of how you actually think, and where that thinking tends to go wrong.
Revenue, margins, filings and reported results come from company disclosures. Every figure carries its period, its source and a link to the original document.
If a number is not available, StockMemo says so. It never fills the gap with an estimate.
The thesis, the conviction, the valuation, the interpretation and the decision are yours, and are labelled as yours everywhere they appear.
StockMemo will never tell you a stock is a buy or a sell. A triggered condition means one thing: your thesis needs another look.
Know why you bought it. Track what has to go right. Review the evidence when it arrives.
