ClearSign Technologies Corp

No net buying or selling imbalance over the last 3 months

No net buyers or sellers account for the net balance. There is no cluster of three distinct buyers within 30 days. We found no CEO/CFO purchases over 12 months.

How to read this signal

Only open-market P purchases and S sales count toward the signal. Vesting, options, taxes and gifts remain in the source data but do not trigger alerts. Rule 10b5-1 trades are shown as informational.

The value is in what we do not call a signal.

The SEC XML stores every transaction. Raspberry keeps that evidence, reads the footnotes and separates voluntary open-market activity from vesting, option exercises, gifts, tax withholding, stock purchase and dividend reinvestment plans and pre-programmed 10b5-1 trades.

As compensation for services as a non-employee director during the quarter ended September 30, 2026, the reporting person was granted non-statutory stock options to purchase 3,766 shares of common stock under the ClearSign Technologies Corporation Amended and Restated 2021 Equity Incentive Plan pursuant to the issuer's non-employee director compensation policy. These non-statutory stock options were immediately vested and exercisable on the grant date.
