William Blair: analyst accuracy FAQ
Does Bullish Whales track William Blair analysts?
Yes. Bullish Whales tracks 58 equity research analysts at William Blair, 38 of whom have a scoreable 12-month history. None have yet reached our minimum number of scored calls to carry a published rank, so this page lists the firm's analysts and their coverage rather than a ranking.
How does Bullish Whales score analyst accuracy?
Bullish Whales scores every rating on real prices. We enter at the closing price on or after the call date, with no look-ahead, then measure the 12-month return above the stock's sector ETF and check whether the price target was reached. An analyst needs a minimum number of fully-elapsed calls before we publish a rank, so a few lucky picks cannot reach the top.

Every score, Win %, PT Hit % and rank is an estimate Bullish Whales calculates from its own data and may not be 100% accurate or complete. Returns are measured in excess of each rated stock's own sector over the 12 months after each call. Past performance does not guarantee future results, and nothing here is a recommendation to buy or sell any security.
