Director Marta Stewart purchased 192 shares of Simon Property Group at $186.00, increasing her holdings from 16,308 to 16,500 shares.

Stewart's prior trades at SPG show mixed timing: 3 of her 5 previous buys at this ticker produced positive 90-day returns, with one acquisition in June 2025 returning +16.4% over 90 days, though her most recent SPG buy on 2025-09-30 underperformed at -6.8% over 30 days. The current valuation reflects a P/E of 25.22 with annual revenue growth of +5.4%, placing the stock -2.8% from its 52-week high of $188.29.

The modest scale of this purchase (42 shares) does not constitute a material signal of conviction relative to her existing 16,122-share position.
