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.

Form 4 raw → Raspberry

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.

Vests in substantially equal monthly installments over a one year period from the February 26, 2026 grant date. Each American Depositary Share ("ADS") represents five ordinary shares, nominal value GBP 0.003 per ordinary share, of the Issuer. Deferred restricted stock units ("DRSU") are granted to non-executive directors who elected to receive DRSUs in the form of ADSs in lieu of annual cash compensation. DRSUs vest in substantially equal monthly installments over the plan year following the grant date. Payment of DRSUs in ADSs will generally be made 180 days following separation of service.

Raspberry interpretation
Informational — no alert
