Selling
Thesis-based selling, durable sell triggers, timing bias, and navigating sunk cost fallacy.
Thesis-Based Selling
Exit only when the business has fundamentally changed, not on temporary headwinds, and hold the decision to a very high standard of evidence.
Durable Sell Triggers
The deliberately short list of genuine reasons to sell a position, and the much longer list of things that are not sell triggers.
Timing Bias
How the tendency to sell at the point of maximum pain systematically destroys returns, and how to build rules that counteract it.
Sunk Cost Fallacy
The risk of holding a failing position because selling feels like admitting defeat, and how long-term investing can mask this bias.
