Smart Money Convergence

ACAD does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

The excerpt here doesn't include any actual figures—like revenue or earnings—so the performance numbers themselves are not visible in this filing snippet.
