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.

Each American depositary share ("ADS") represents two (2) Class A ordinary shares, with a par value of US$0.0001 per share, of Niu Technologies (the "Company"). Represent 90,000 Class A ordinary shares of the Company received in the form of ADSs upon vesting of the 90,000 restricted share units granted to the reporting person on March 15, 2022. See footnote 5. Each RSU represents the contingent right to receive one (1) Class A ordinary shares of the Company upon vesting. The reporting person sold 22,113 ADSs solely to satisfy tax obligations incurred upon vesting. The 90,000 RSUs were granted to the reporting person pursuant to the Company's 2018 Share Incentive Plan (the "2018 Plan") on March 15, 2022, and vested on March 15, 2026.

Raspberry interpretation
Informational — no alert

Reason: tax_withholding. The filing footnotes identify tax withholding.
