Rosenbaum Michael George, chief executive officer of Guidewire Software (GWRE), has filed 83 Form 4 transactions across two companies, with every open-market trade a sale. His total sell value is $36.8 million, and he has recorded no open-market purchases, no acquisitions, and no recent buys. The pattern is one-directional: 22 sales in the most recent stretch, all in GWRE, with no purchases in any period covered by the filings. The recent trades show a steady weekly cadence. From June 16, 2026 through November 2, 2026, George sold GWRE shares in 22 transactions, with values ranging from $126,804 on June 22 to $10.4 million on September 17. The September 17 sale is the largest single transaction, and it follows an option exercise on September 15 with a reported value of zero, which is mechanical. A grant on September 11 also carried a zero value, meaning it was compensation, not a purchase. The weekly sales otherwise cluster between roughly $150,000 and $245,000, with the June 16 sale at $692,271 as an outlier. The filings also include a zero-value option exercise in DOCU on September 3, but no accompanying sale in that ticker appears in the recent data. George's activity is entirely sell-side in GWRE, with the only non-sale events being compensation grants and option exercises that do not change his cash position. The absence of any P-coded purchase in his entire filing history means his disclosed insider behavior is consistently bearish in direction, though the size of each sale is modest relative to the September 17 block.
