Uber COO Buys $5.3M; Insiders Pile In

Uber Technologies' President and COO Andrew MacDonald filed on September 8, disclosing he purchased 70,000 shares worth $5.3 million on September 4. The open-market buys — not tied to a 10b5-1 plan — represent a strong discretionary signal of confidence in UBER, which carries a market cap of roughly $146 billion.

Two directors at psychedelic medicine firm HELP (Cybin Inc.) also filed on the same date. Eric So and Paul Glavine each bought $1.2 million worth of shares on September 3–4. The coordinated buying by two board members adds weight to the signal. Cybin's short interest stands at 5.1% of free float.

Elsewhere, Korean gaming giant Netmarble accumulated shares of COWAY — the South Korean home appliance firm — across four separate trades between September 3 and 8, totalling roughly $7.7 million. Cluster buying by a major shareholder over multiple sessions often reflects deliberate accumulation ahead of a catalyst.

On the sell side, JPMorgan disclosed significant reductions in several Hong Kong-listed Chinese stocks on September 2, including a $85 million cut in Kingdee International Software and a $71 million trim in Sunny Optical. These are institutional position adjustments, not corporate insider sales — the signal is weaker.

The standout trade remains the Uber COO's discretionary purchase. It came at a price of roughly $75 per share, and with no 10b5-1 plan attached, it is among the cleaner C-suite buy signals filed this week.
