What "sell the news" actually means

Here is the cleanest example in modern markets of an idea most people never quite absorb.

In July 2022, Ethereum’s developers set a date for an upgrade that had slipped for years. The change was public, dated and understood. Over the next eight weeks the price doubled.

On 15 September the upgrade completed. It worked perfectly, on the promised day, doing exactly what had been promised.

The price fell. Six days later it was down 22%.

Nothing went wrong

That is the part worth sitting with. There was no failure, no delay, no bug. The event happened as advertised and the price went down anyway.

The mechanism

A price is not a score for how good the news is. It is the level at which the next buyer and the next seller agree. When something is announced, dated and discussed for two months, everyone who was going to buy it because of that reason has already bought.

On the day, there is nobody left.

So the question that matters is never is this good news. It is:

Is this better than what people already expect?

Good news that was expected moves nothing. Mildly disappointing news against enormous expectations can take a quarter off a company’s value in a day — which is exactly what happened to Meta in February 2022, on results that still ran to billions in profit.

Where this bites beginners

The instinct is to buy things you have heard are good. By the time you have heard, so has everyone else, and the price has moved to reflect it. Being late to a correct idea is one of the most reliable ways to lose money while being right about the world.

Knowing the mechanism does not make you immune. Practising it might.
