Top Momentum & Conviction
Stop cross-referencing SEC filings by hand. AlphaSMO already did it.
Instantly see stocks where 13F institutions and corporate insiders are buying at the same time — historically the strongest conviction signal hiding in SEC filings.
Every fund gets an AI-narrated snowflake profile — concentration, momentum, sector conviction, and sizing style — so you know how a manager actually invests, not just what they hold.
Track quarter-over-quarter capital rotation across every GICS sector, and follow individual funds' buy/sell changes the moment new 13F filings post.
Real feedback from traders, researchers, and developers building on AlphaSMO.
I used to open a dozen SEC pages every quarter just to cross-check 13F filings. With AlphaSMO's Smart Money Convergence, I see executive Form 4 buys and institutional accumulation overlap in one panel — it's cut my prep time by more than half.
A lot of stock-ownership sites update too slowly, and some just patch together estimates or news screenshots. AlphaSMO links straight back to the original SEC EDGAR Form 144 and Form 4 filings — for anyone doing serious research, that data purity matters a lot.
Pulling AlphaSMO's data through LobeHub and the MCP Registry is seamless. I didn't have to build my own scraper to parse SEC EDGAR's XML/HTML filings — my AI agent can just read the latest smart-money flows directly.
Flagship Signal
When a company's own executives are buying alongside dozens of 13F funds in the same quarter, that's not noise — AlphaSMO surfaces this convergence automatically, ranked by conviction score, unique insider count, and net institutional flow.
