Ernest S. Rady, Executive Chairman, Director, and 10%+ owner of American Assets Trust, Inc. (AAT), continued an extended run of open-market stock purchases on September 2, 2026, buying 96,636 shares at $22.50 apiece for a total of $2,174,310.00. The shares were acquired indirectly, through a trust or entity structure, and bring Rady’s indirectly held stake to 2,413,658 shares.
This latest purchase is not an isolated event. It marks the seventh open-market buy from Rady in a ten-day window spanning August 24 through September 2, 2026, with the combined value of that stretch now totaling $7,815,447. The size and cadence of the buying, spread across multiple trading days rather than a single lump transaction, is why our system flags this filing as a cluster buy, our internal classification for repeated insider purchases concentrated in a short period.
A Pattern That Keeps Growing
We first covered this activity when Rady’s August purchases reached $4.39 million, and the buying accelerated from there. Readers can review the earlier stage of this spree in our prior report, AAT: Rady Buys $1.14M More, August Spree Hits $4.39M, which tracked the run-up before it crossed the $7.8 million mark. Each subsequent filing has added to the same underlying position rather than representing a new or unrelated trade.
What stands out here is not just the dollar total but the consistency: seven separate transactions, each disclosed on its own Form 4, all pointing in the same direction. Rady’s role as Executive Chairman and a significant beneficial owner means these purchases are being made by someone with direct visibility into the company’s operations and strategy, which is part of why clustered insider buying tends to draw attention from market watchers.
Academic research on insider trading disclosures has found that clustered buying, multiple insiders or repeated purchases by the same insider within a short window, has historically correlated with periods of subsequent outperformance in the underlying stock, on average and across large samples of filings. That is a statistical observation about disclosure patterns generally, not a statement about what will happen with American Assets Trust shares specifically, and it should not be read as a forecast or a suggestion to take any action.
As of this filing, Rady’s indirect holdings in AAT stand at 2,413,658 shares. Whether additional purchases follow in the coming days remains to be seen, but the pattern established over the past two weeks, seven buys totaling nearly $7.8 million, is now firmly on the record.
