Setia Vishwas (CFO) sold 33,382 shares of MapLight Therapeutics, Inc. on Jan 27, 2026, a filing that scored 94 (Strong).

Cluster activity
A cluster buy is present: 8 insiders (Malenka Robert C., Setia Vishwas, Lillie James Woodruff, Kreitzer Anatol) traded MPLT the same direction within a 7-day window. Shared conviction is a stronger structural signal than a lone trade.

Open-market buys make up 7% of the 163 scoreable MPLT transactions on record between Jan 27, 2026 and Oct 15, 2026. Comparing a filing with the company's own buy/sell mix is how you tell a routine disposal from an unusual accumulation.
