FORTUNE — In the words of Jason Schwarz:

“If you can keep a good stock down then you are able to load up for the ride back up. It’s like a slingshot — the harder you pull, the more propulsion you generate.”  — Apple: Seven reasons shorts love it

There was a lot of pent-up value in Apple (AAPL) on Tuesday April 24, the day it was scheduled to release its fiscal Q2 earnings.

Exactly two weeks earlier, the stock had capped a four-month bull run by hitting an all-time intraday high of $644 a share.

Over the next 10 trading days, in what one analyst called “panic profit taking,” the stock fell 13.8% to hit, shortly after 2 p.m. Tuesday, $555 a share. (See Cocking the Apple slingshot.)

With 932.37 million shares outstanding, Apple’s market capitalization had just been reduced by $83 billion. For that kind of money, you could almost buy Amazon (AMZN).

The next morning, Apple opened at $615.64. In one clock tick, the company had gained $57 billion in market value, or roughly one Goldman Sachs (GS).

That’s a lot of throwing power, even for a slingshot as big as Apple.
