Game Theory Scenarios

Bullish— Smart Money Convergence

LRCX Institutional Accumulation Dictates Bullish Sentiment

Signal Basis

13F filings for Q1 2026 reveal institutional net accumulation of $35.3B, with 1,250 buyers vs. 1,188 sellers and 365 new buys against 113 exits. Insider activity is limited to a single $11.7M sale by CEO Archer, marginal relative to the institutional flow.

Confirmation

Continued institutional accumulation in the next 13F cycle or the emergence of insider buying would confirm the bullish stance.

Invalidation Risk

A sustained insider-selling campaign or a reversal to institutional distribution would invalidate the bull case.
