Insider selling dominated the screen this week, with the biggest disclosed volumes concentrated in tech and energy names.
CrowdStrike led the sell-side activity over the past month. The cybersecurity giant's stock is down 44% year-to-date, yet insiders have been sellers rather than buyers. With a $268B market cap and short interest sitting at just 2.6% of free float, the selling reads as distribution into a stock that has struggled badly in 2026.
Diamondback Energy showed the largest insider sale volumes among energy names. The Permian pure-play has gained 32% year-to-date. Insiders selling into strength is a weaker signal than distressed selling, but the scale of disclosed exits is notable heading into Q3 earnings.
Lennar stands out on the buy side. The homebuilder has shed 27% this year. Short interest sits at 11.8% of free float, one of the higher readings among large-cap housebuilders. Insider buying into that kind of drawdown carries more weight. The US CPI-U all-items index hit a record September high of 336.94 in 2026, per ORTEX Alt Data, keeping mortgage rate pressure elevated, context that makes any discretionary purchase by Lennar management more pointed.
