Here's what i think happened with AMD, for the last 5 years or so every single one of their earnings reports has yielded in a drop on the ER reveal regardless of what the actual earnings report says about the company.

Knowing this a high frequency algorithmic trader or some nerdy quant fuck would plug that information into whatever trading formulas he has for playing earnings reports and trades would execute at or near the market close.


nearly 4.5 million shares were moved in the final 5 minutes of trading on October 20th which was likely huge amounts of high frequency traders loading up on shorts.

The first minute into after hours at 15:01, another 1.12 million shares got moved.

A stray trade sent the price up from $7 to $7.20 which likely caused the high frequency algorithms to misbehave and either start dumping their shares or loading up on shorts. Due to the nature of high frequency trading, the market effectively froze up for a couple seconds causing the price to fall rapidly as High frequency trading algorithms were desperately looking to dump their shares while nobody was on the receiving end to buy them in after hours. With no human traders to buy shares the HFTAs hunted for limit buys way down the price structure both appeasing their desire to get a good price for their short sales and trying to minimize losses by selling as fast as they can. Once a couple limit buys get triggered a ridiculous number of stop losses get triggered driving the price down even more in the minute after the flash crash.

The HFTAs also might have blocked channels of liquidity for a couple of seconds by flooding finance channels with what is essentially a denial of service attack stopping any fast acting buy orders or anything else that could provide liquidity to the stock making shorts money

Liquidity was completely dried up for a few second while the HFT algorithms caused a flash crash in the stock similar to the 2010 crash and the flash crash in GBP a couple weeks ago.
