The pre-market selling pressure is interesting.

First, the downward move isn't as strong as last night's surge.

Second, the main character $Alphabet(GOOGL.US) is seeing a slight increase.

So, my conclusion is:

Wall Street has already "heard" about GOOGL's earnings information and started market making to guide retail investors to bearish sentiment on the earnings before the 'sell the news' event, so they can enter at lower prices. After the market closed, once GOOGL's earnings were released, institutions began releasing a flood of positive news, capital flooded in, and tech stocks soared. $Roundhill Memory ETF(DRAM.US)$SK Hynix(SKHY.US)$Micron Tech(MU.US)$Sandisk(SNDK.US)
