Ernest S. Rady, Executive Chairman and Director of American Assets Trust, Inc. (NYSE: AAT), disclosed another open-market purchase of the real estate investment trust’s stock, according to a Form 4 filed with the SEC. On August 26, 2026, Rady bought 50,000 shares at $22.89 apiece, a purchase worth $1,144,500.00. Following the transaction, Rady’s indirectly held stake — through a trust or affiliated entity — stands at 8,995,846 shares.
This latest buy is not an isolated event. It is the sixth open-market purchase by Rady in a ten-day window running from August 17 to August 26, 2026. Combined, those six transactions total $4,394,604 in insider buying, all funded with Rady’s own money rather than through option exercises or other compensation-linked mechanisms. The pattern places Rady’s activity squarely in the category whoisbuyingnow.com classifies as a cluster buy — multiple purchases by the same insider concentrated in a short timeframe, a signal that tends to draw more attention from market watchers than a single transaction in isolation.
A Pattern Worth Watching
Because Rady holds roles as Executive Chairman, Director, and a 10%-plus owner of American Assets Trust, his trading carries weight beyond that of a typical rank-and-file executive. His stake gives him visibility into the company’s operations and strategy that few outside shareholders possess, and the sustained nature of this buying — six separate purchases rather than one large block trade — suggests a deliberate, ongoing decision rather than a one-time move. Academic research on insider trading has found that clustered purchases by multiple insiders, or repeated purchases by a single well-positioned insider, can statistically correlate with subsequent outperformance, though such findings describe historical patterns across large samples and are not a forecast for any individual company or filing.
This is not the first time American Assets Trust’s insider activity has drawn coverage. Earlier reporting tracked the spree as it developed; readers can find additional detail in our earlier piece, AAT: Rady’s Buys Hit $8.25M in 7-Trade August Spree, which chronicled the buying as it accumulated across the month.
As with all Form 4 disclosures, the filing reflects a transaction that has already occurred and been reported to the SEC as required by law. It offers a window into how a company’s largest insider is positioning his own holdings, but it does not constitute guidance on how any other investor should act. Whether this cluster of purchases continues, pauses, or expands further will depend on decisions yet to be disclosed in future filings.
