|---|---|---|
| answer | A stock's full read in one call: the standing investment case, valuation off its filed financials, and the latest quarter. Use when the user asks: is X a buy; is X cheap; what are X's earnings; how was X's quarter; did X beat. response_mode=plain for beginners. Not for: several companies → compare. Args: entity; response_mode. | Read-only |
| compare | Two or more companies side by side: each one's valuation, investment case, and what supports or challenges it, so the comparison rests on the cases, not just ratios. Use when the user asks: X vs Y; which is the better buy; is X or Y more defensive. response_mode=plain for beginners. Not for: one company → answer. Args: entities (2-5). | Read-only |
