Instead of making large initial bets, a more effective strategy is to take small, "junior varsity" positions. Investors then aggressively ramp up their size only when the thesis begins to demonstrably play out, a method described as "high conviction, inflection investing."

The optimal exit point for a discretionary trade isn't determined by valuation metrics, but by market psychology. The signal is when investors betting against the trend are experiencing maximum financial and emotional pain, an intuitive skill that cannot be codified into a system.

Success in late-stage venture resembles trading more than traditional investing—it's about buying and selling on momentum. However, this "new public market" has a critical flaw: while liquidity exists on the way up, it vanishes on the downside, making it impossible to execute a true trading strategy when a correction occurs.
