The week in buying

Summit's $100M insider buy dominates quiet week

Summit Therapeutics (SMMT) drew the week's headline with a single $99.97M insider purchase tied to a material 8-K filing, dwarfing all other activity. SSMR showed the week's largest cluster with five insiders collectively buying $804K, while banking stocks BWFG and MBBC each drew clusters of five and four buyers respectively but with modest dollar totals. Overall a thin week with 49 companies tracked—most driven by small individual transactions rather than broad conviction.
