For the price to rebound, we would need there to be people willing to both buy and sell the stock at the old price. To the extent that the supply of buyers was reduced (since their desire to buy was satisfied) by a major shareholder’s cat dumping their stock, we would need to find some new buyers.
But there are people coming in/out of the market all the time—not everyone who was ever going to have an interest in Facebook stock was waiting with a bid order on the books for the cat to sell into.
Let’s say for sake of argument that the “true and actual” value of a share of Facebook stock (based on some platonic ideal analysis of the time-discounted sum of all its future dividends) is $235. Even if the cat manages to sell enough stock to temporarily punt the price down to $200, it will still be true that the sum of future dividends is $235.
There will then be a quick profit to be made by anyone noticing the discrepancy who’s willing to offer to buy at $205, who will in turn be outbid by those offering $210, or $230, or $232, or $233.50… and that’ll bring the price back into line with where it “ought” to be. There doesn’t need to be a large quantity of shares traded at those prices, because spot price is just based on the most recent trade. And if there aren’t any (non-cat) sellers willing to sell below $235 then anyone wanting to buy Facebook stock at all will need to meet their terms.
In the textbook-ideal case this would all happen almost immediately. In practice probably it would take a bit longer for the market to figure out the big sale was an irrational actor; meanwhile some people with an urgent desire to sell will have started offering at $230 or $225, so there will be a bit of churn before things settle.
Why is selling an investment at the market’s highest value point in history irrational? Because it might be at an even higher value point in history later, and by selling you practically ensure that it’ll take longer to reach the next peak?
I don’t think the price being at an all time high was a necessary, intended, or … even explicitly included part of the story I was telling. I picked the price numbers purely for purposes of illustration, by looking up the current price and rounding it—the specific number wasn’t intended to be significant.
The sale is irrational because it’s performed by a cat, who (presumably) has no useful information or analysis about the value of the company and its stock.
If the sale were being undertaken by someone intentionally, on the basis that they think Facebook isn’t worth as much as the current price implies, that would imply the existence of information that the market price should respond to.

oh oh oh oh I get it, I was reading the current story onto the story you were actually telling
thank you!
