Smart Money Convergence

CALC 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.

CalciMedica published an 8-K on August 11, 2026, saying it had issued a press release with its financial results for the quarter ended June 30, 2026. The filing itself only confirms the press release exists; it doesn't include the actual numbers or a discussion of performance. It also notes the release is furnished, not filed, so it won't count as an SEC-filed document for liability purposes.
