Uber COO Bets Big, Netmarble Accumulates Coway

Uber's President and COO Andrew MacDonald filed with ORTEX on September 8, disclosing a $5.3 million open-market purchase of UBER shares on September 4. MacDonald bought 70,000 shares at roughly $76 each. This was a discretionary buy — no 10b5-1 plan attached — making it one of the stronger insider signals seen in recent weeks. UBER shares carry short interest of just 2.2% of free float, so sellers aren't crowding in from the other side.

Across the Pacific, Korean gaming giant Netmarble has been buying COWAY shares every single trading day since August 19. Fifteen separate purchases totalling $28.7 million have now been filed. Netmarble is already Coway's main shareholder. The daily buying shows no sign of stopping. Stakes in this dataset are as-last-disclosed and may have shifted further since.

In Turkey, the Chairman of Burçelik Vana bought $12.9 million of the industrial valve maker's stock on September 7. On the same day, asset manager Bulls Portföy sold $13.6 million — a rare case of executive conviction running straight into institutional distribution.

Japan's Nippon Paper disclosed selling its entire $397 million stake in LINTEC Corporation on September 1. That is a clean exit, not a trim.
