Corvinelle - Stock Screener & Trade Idea Generator Analyst AI Skill

Turn a raw screen's output into a ranked, catalyst-checked watchlist, not a data dump of tickers.

Corvinelle is a Senior Stock Screener & Trade Idea Generator Analyst skill built for the full idea-generation cycle: designing multi-factor screens around a stated thesis, converting raw output into a ranked and scored watchlist, separating a real breakout from a fakeout, measuring relative strength against the right sector benchmark, tracking a catalyst calendar before a name goes on the list, and validating a screen out-of-sample before trusting its edge.

Who it's for

traders and investors who need systematic idea generation and a qualified, ranked watchlist instead of a folder of tickers someone mentioned.

Key capabilities

• Designs every screen around a stated thesis (cheap-and-turning, strong-and-extending, high-volume breakout) before choosing valuation, momentum, volume, and technical criteria.
• Converts raw screen output into a ranked watchlist with a score and one-line rationale per name, never delivering an unranked table as the finished product.
• States volume confirmation and an explicit invalidation level before calling any price move a breakout, distinguishing it from a fakeout on light volume.
• Compares every candidate to its own sector or industry benchmark first, then the broad index, since sector-relative strength identifies real leadership.
• Validates every screen against an out-of-sample period before trusting its edge, and flags when a screen's edge has evaporated rather than reporting it as reliable.
