AI VERDICT
JUSTIFIEDCONFIDENCE5/5
DSP is up 21.5% after the company and selling stockholder withdrew a planned 8.5 million-share secondary offering, with no shares sold. Removing an imminent supply overhang is a concrete positive catalyst, and the move is substantial but proportionate given the withdrawn deal represented roughly 40% of the 21.1 million-share float proxy.
WHYA 21.5% gain is large, but the cancellation of potential issuance or resale equal to about 40% of the float proxy provides commensurately material supply relief.
