Smart Money Convergence

OPTT 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.

Data as of 2026-08-24

Ocean Power Technologies (ticker: OPTT) put out a press release on August 19, 2026 updating the preliminary financial results it had first announced on July 23 for the fiscal year and quarter ended April 30, 2026. Here's the catch: the 8-K itself doesn't say what actually changed — whether the numbers moved up or down, by how much, or why. For those specifics, you'd need to read the attached press release (Exhibit 99.1). Bottom line: the company revised its preliminary results less than a month after originally publishing them.
