ByteDance stock trading legend makes 30 million and quits: Bought a hard drive on Pinduoduo, discovered a 6x stock Leto Bao, the protagonist of ByteDance's $30 million stock trading success story, shared how he stumbled upon a 6x stock while buying a Seagate high-capacity hard drive on Pinduoduo. He noticed the same model kept increasing in price over a week—only going up, never down. Instead of stopping at the thought, "It's getting more expensive," he dug deeper into the signal: AI data centers were massively purchasing nearline HDDs → supply was squeezed, impacting retail prices → checked financial reports to confirm fundamentals → used 13F filings to verify institutional holding trends, which showed consistent growth over several quarters. He ultimately went heavy on STX, achieving a 6x return in just over a year. He summarized his logic into four steps: → Spot unusual patterns in daily life → Track price trends to confirm momentum → Identify beneficiaries in the supply chain → Use 13F filings to validate institutional sentiment.
