New: QL Street Grades
A bank upgrades your stock and the headline writes itself — but did that firm's last six calls on this name actually work? QL Street Grades takes up to six years of Wall Street rating actions on any ticker and grades them against what the stock actually did. We grade the Street the way we grade ourselves: logged actions, realized returns, receipts.
What you get
- Upgrade & downgrade scoreboard — median 1m/3m/6m returns after upgrades and downgrades, next to the stock's own unconditional drift ("the tape"), with win rates and sample counts. The headline number is the 3-month upgrade edge: did following upgrades beat just holding the name?
- Price-target reality check — of the 12-month targets old enough to judge, how many were actually reached? Median promised upside vs median delivered return.
- Firm leaderboard — which firms' calls on this name beat the tape (minimum 3 graded calls), and which have been reliable contra-indicators.
- Honest math — forward returns start at the close of the action day (analysts publish premarket, so the day's pop is already in the entry). Calls too recent to have a full window are excluded, never padded.
For developers and AI agents
The same data ships in the public REST API — GET /api/v1/street-grades?ticker=NVDA, available on every key tier including Free (docs) — and as a street_grades tool on the QuantLogix MCP server, so Claude, Cursor, or any MCP client can answer "should I trust this upgrade?" with evidence mid-conversation (setup).
Where to start
- Open /street-grades — NVDA loads by default; try the names you hold.
- Next time an upgrade crosses the wire, check the issuing firm on the leaderboard before you act.
- Find it any time in the Free Tools hub under Signals & Screening, alongside the other ticker-history labs: Seasonality, Gap Stats, and DCA Lab.
