Buyers Step In as Sellers Dominate S&P 500 Insiders

The ORTEX first-party SEC EDGAR tables were unavailable in this environment, so transaction-level Form 4 data and Schedule 13D activist filings could not be retrieved directly. The analysis below draws on ORTEX screening data covering the past month across S&P 500 constituents.

Insider buying was most active at LEN, ORCL, and TFC over the past month. Lennar led all S&P 500 names by value bought. The homebuilder is down 27% year to date. That combination of a depressed price and fresh buying is worth watching ahead of its Q3 earnings call. Lennar also issued $600 million in new senior notes this week, rated Baa2 by Moody's.

Oracle ranked second by insider buying value over the month. The stock has fallen 26% year to date. Its analyst consensus implies 66% upside to target price, the widest gap among large-cap software names in the index.

On the selling side, FANG, CRWD, and NVDA recorded the heaviest insider disposals over the past 30 days. Diamondback Energy insiders sold despite the stock gaining 32% year to date. Mizuho kept its Outperform rating on Diamondback this week. CrowdStrike insiders also sold heavily. The stock is down 44% year to date. That makes the selling harder to read as routine profit-taking.

Simon Property Group and Elevance Health showed the strongest positive insider momentum scores among large-caps. Both names recorded net buying pressure over the one-month window. ELV is up 21% year to date and insiders continued adding to positions.
