Smart Money Convergence

DIOD 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.

No specific financial figures are shown in this filing itself, and it notes these non-GAAP measures are supplementary, not replacements for GAAP, and may not be comparable across companies.
