Why it matters

The newest fact is the specific open-market sale size, price, and post-transaction holdings; it may slightly affect sentiment but does not change company fundamentals in the text.

02

Market read

Traders may monitor DSP for sentiment drift from insider selling, but there is no guidance, earnings, or deal catalyst here.

What to watch
