The mistake I used to make in crashes was thinking like a calm investor while the market was full of desperate sellers. That is what March 2020 taught me.

Prices were falling every day. Good companies were getting cheaper. Index funds were getting cheaper. Stocks that looked attractive on Monday looked even cheaper by Wednesday, and still the market kept falling.

That is the trap. Your spreadsheet says the price is attractive. Your mind says the business is strong. Your long-term logic says this should be an opportunity. But the seller on the other side may not be thinking about value at all. He may be meeting a margin call. He may be a fund forced to raise cash. He may be a retiree watching years of savings disappear. He may be someone who simply cannot take another red day.

That seller is not asking, “What is this business worth?” He is asking, “How do I get out?” And when enough people are asking that question at the same time, price can fall far below logic and still keep falling.

That is why cheap does not stop panic. A stock can be cheap at $100, cheaper at $80, a bargain at $60, and still trade at $40 before the selling is finished. That does not mean valuation is useless. It means valuation is not timing. In calm markets, valuation matters. In panic, liquidity matters first.

The bottom does not arrive when price looks cheap. It arrives when sellers are exhausted.

That is why I stopped trying to argue with panic. I do not ask only, “Is this cheap?” I ask, “Is panic still in control?” If price is still making new lows, panic is still in control. If every bounce gets sold, panic is still in control. If volatility is expanding, panic is still in control. If even strong names cannot hold support, panic is still in control. Only when the selling starts to weaken does logic begin to matter again.

That is the lesson. You cannot fight panic with logic. You wait until panic runs out of sellers.

In a panic, valuation is rarely support. Valuation is an argument. Panic is pressure. Sometimes that pressure comes from margin calls, sometimes from funds needing cash, sometimes from investors who simply cannot take the pain anymore. Those sellers are not trying to calculate fair value. They are trying to survive the moment. That is why price can fall far below a reasonable estimate of value and still keep falling.

This is the difference between being right and being early. You can be right that a stock is cheap and still lose money because the market has not finished panicking. You can be right that the business is strong and still watch the price fall another twenty percent. You can be right on value and wrong on timing.

In a crash, the first job is not to prove that you are rational. The first job is to survive until rational pricing returns. Price is the final vote, and during panic that vote is often cast by fear, forced selling, and the need for cash.

So do not fight panic with logic. Wait for panic to weaken. Then let logic matter again.

A panic is when investors sell because they want cash, not because they calmly recalculated the value of a business. A margin call happens when someone bought stocks with borrowed money and the broker forces them to sell after prices fall too far. That selling can happen at any price; the seller may not care whether the stock is cheap. Valuation means estimating what a business is worth.

In normal markets, valuation can help. In a panic, valuation may not stop the fall because forced sellers and fearful sellers are setting the price. A weekly chart shows one price bar per week.

It helps filter out daily chaos and shows whether selling pressure is starting to calm. The lesson is simple: cheap does not mean safe if panic is still in control.
