Some pretty large insider purchases were reported this week. The biggest one was at W.R. Berkley (WRB). Mitsui Sumitomo bought another $92.3 million worth of shares. They already own over 13% of the company and seem to be targeting a 15% stake by 2026. Biotech activity was high too. Aktis Oncology (AKTS) saw insiders put in nearly $79.3 million right after their IPO. Alumis (ALMS) directors bought $17 million in shares following a secondary offering, even with the stock up on recent trial results. A few others worth noting: * Micron (MU): Director bought ~$7.8 million * Hycroft Mining (HYMC): 10% owner bought ~$6.6 million * Transcontinental Realty (TCI): 10% owner bought ~$3.9 million
