Why AerInvest
Three things every investor needs to know.
Know what it's worth
A fair-value estimate blended from a DCF model, relative multiples against sector peers, and an AI quality score — with the bear, base and bull case shown, not hidden behind one number.
Know what can go wrong
Real-time SEC filing summaries, balance-sheet pressure signals and portfolio risk exposure — the parts of the picture a stock chart alone will never show you.
Know when the thesis changes
Write down why you own something. AerInvest watches the fundamentals and tells you when they diverge from that reasoning — not just when the price moves.
Try it — no account needed
Search a stock. See the thesis.

Research engine
Research that goes beyond the chart.
