Panic Selling
Panic selling turns a temporary price move into a permanent decision.
Why it matters
Most permanent losses in diversified portfolios aren't caused by markets. They're caused by exits.
In plain language
A falling price is an event; selling into it is a decision. Panic selling is when the decision is made by your heart rate instead of your plan — usually near the bottom, because that's where the fear is loudest.
The mechanics are cruel: panic peaks when prices trough, so the urge to sell is strongest at the worst possible moment. The market then recovers without you, and the temporary loss becomes yours permanently.
The defense is built before the storm, not during it: position sizes you can survive, cash that means nothing must be sold, and a plan written by the calm version of you — because the panicked version will follow instructions she finds, not invent good ones.
In real life
Selling the apartment during the one terrible year of the neighborhood — to buyers who'd read the same headlines — then watching the street recover in three. The neighborhood was never the problem; the timing of the exit was.
In the market
In The Season, the SELL ALL button appears exactly when stress peaks. Pressing it always feels like relief; the game — like markets — invoices for that relief later.
The common mistake
Confusing 'making the feeling stop' with 'managing risk'. Real risk management happened weeks earlier, in the sizing. At the bottom, selling mostly manages the feeling.
“The feeling is information. It is not an instruction.”
Quick self-check
Your portfolio is down 20% and you desperately want to sell everything. What's the first question worth asking?

'What changed — the value of what I own, or how I feel?' If only the feeling changed, the sale isn't strategy; it's paying the market to hold your anxiety.
