Smart Money Convergence

STIM 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.

Neuronetics, Inc. (ticker: STIM) issued a press release on August 11, 2026, reporting its financial results for the three and six months ended June 30, 2026, and attached that release as an exhibit to this 8-K. The filing says the information is being furnished, not filed, so it carries different legal weight from a formal SEC filing, and the company isn't committing to update it. The provided excerpt only covers Item 2.02, though the filing also lists other items.
