Assuming near-perfect win rates are a primary signal for insider trading could lead to some serious drawbacks; we need to be careful with such strong claims. A high win rate with minimal selling might just mean someone has deep, specialized knowledge in a niche area, not that they're cheating. For example, a specialist knowing every detail about Swiss pharmaceutical approvals could consistently win bets on drug launches without any insider tips, just through public domain expertise. We always need to check for verifiable expertise before jumping to conclusions about illicit activity.
