An illustration of the interface. StockGuard only ever shows readings a data provider actually published.
The difference
price alerts tell you what happened. StockGuard tells you what changed.
StockGuard
Thesis alert
Gross margin fell below your 70% threshold.
This affects one of your thesis rules.
You wrote the threshold. StockGuard only had to tell you the line was crossed.
How it works
three steps, then it runs without you.
01Build
Choose a stock and define what matters.
Revenue growth, margins, guidance, insider activity — the conditions you are actually relying on.
02Watch
StockGuard monitors those conditions.
Filings and provider data are checked on a schedule. Every reading records its source and the moment it was taken.
03Know
Get alerted when your thesis changes.
Only when a rule you wrote crosses the line you drew. Everything else is filed under What Changed.
Thesis rules
watch the reason, not just the price.
A rule is one condition you are relying on, with the line you would want to know about. Write six of them and you have written down your thesis.

Some things no provider publishes as a clean, checkable field — guidance language and management changes among them. StockGuard keeps those as manual rules you update yourself rather than pretending to watch them.
Thesis check
every quarter, against your own rules.
Instead of reading every earnings report manually, StockGuard checks the numbers against the rules you already chose.
The result is filed against the thesis, so a year later you can see which quarter the story actually changed — not just which quarter the price did.

Thesis history
remember why you bought it.
StockGuard keeps a permanent record of every change to a thesis — what you wrote, when it was checked, and what moved.
Two years on, the question is rarely “how has it done”. It is “did the reason still hold” — and that is a question only a record can answer.

Start here
start with one company.
Pick a stock you already own and write down why. It takes about three minutes, and from then on the reason is being watched rather than remembered.
No trading. No brokerage connection. No portfolio to import.
