ByteDance Employee Nets 30 Million Yuan from Stocks: Post-Mortem
A ByteDance employee recounted on Odaily how he profited 30 million yuan (approx. $4.2 million) from stock trading and subsequently resigned. His investment framework: be attentive to daily anomalies — for example, when a frequently bought item inexplicably rises in price, ask why. Identify the publicly listed company behind the price change. Then cross-check the company's 13F filings (mandatory quarterly reports filed by institutional investment managers with the SEC) to see if professional money managers also hold the stock. This simple pipeline — anomaly → company → institutional verification — can uncover asymmetric opportunities. He emphasized that the journey began with a seemingly trivial observation about two hard drives from Pinduoduo, which led to a deeper understanding of supply chains and listed suppliers. The methodology applies broadly to any consumer-facing sector where price changes reflect underlying shifts in corporate earnings.
