Director Rapaport-Dagim buys 40,000 shares of SMWB at $3.22; holdings jump 169.6% to 63.6K shares

Director Rapaport-Dagim Tamar purchased 40,000 shares at $3.22 on 2026-05-18, substantially increasing her stake from 23.6K to 63.6K shares (a 169.6% increase in holdings). The transaction occurred at a price that sits -65.5% from the 52-week high of $10.75, and the stock has recovered 45.5% over the past 90 days and 41.1% over the past 30 days. This is a discrete, material accumulation by a director at a depressed absolute price level, though timing relative to recent momentum cannot be characterized without explicit scheduling information. The transaction value of $128.9K and the 63.6K post-transaction share position are now visible to the market and may attract scrutiny regarding the director's confidence in the firm's trajectory.
