How Exent scores analysts

Exent replays every rating with a price target over a 7‑year lookback: was the target reached, how long it took, and what the stock returned 1, 3, 6 and 12 months after the call. The star rating and rank combine success rate, average return and the number of ratings, so a few lucky calls do not make a top analyst. Statistics as of Jun 24, 2026; ranking updated Oct 20, 2026. How accurate are analyst price targets overall?
