Several top holdings in AI investor Leopold Aschenbrenner’s portfolio have pulled back significantly since reaching October highs. SanDisk (SNDK) dropped 19%, Micron (MU) fell 14%, and SharonAI (SHAZ) declined up to 30%, while CoreWeave (CRWV), Nebius (NBIS), and Bloom Energy (BE) posted losses of 13%, 11%, and 6% respectively.
