What is that one stock you once had high conviction in, but it never reached the fair value you had in mind?

The commenter explicitly states they will hold RDDT “till I’m in the coffin, or it reaches at least 320B (10x).” Past regret on META (sold before it reached fair value) reinforces a decision to hold RDDT regardless of short-term volatility, implying a multi-year conviction. High-conviction, extremely bullish long on RDDT with a fixed price target (10x current market cap, implying ~$320B). No fundamental analysis is provided, but the conviction is clear. No valuation support; unrealistic multiple expansion; social media competition; user growth deceleration; market cap target may never materialize.
