Recent Form-4 filings via Nasdaq. Open-market buys are the signal worth watching. Grants and automatic (10b5-1) sells are routine. “% of position” is the share of that insider’s own holding the trade moved. Not investment advice.

Dilution watch

Unavailable

We could not reach SEC EDGAR, so the dilution check did not run for $ABOS. This is not a clean result: there may be an offering, a registration or a shelf on file that we were unable to read. Check it yourself on SEC EDGAR before trading it.
