Stock always dip on earnings. It's the way hedge funds and day traders like to scam the market. They scare small investors into selling and then they buy back at a lower price.
Marketwatch for the last 10 minutes has been posting deliberate fake news that the stock has dropped between 1.5 to 2 percent even though it's less than 1 percent. That's how you scam the public. Scare them one day, hype the next day, scare the next, repeat.
See screenshot.
As for 'estimates'. That's another scam the investment institutions play on you. They get the original estimate from the company. Then add some more on top to make you buy more shares and pump up the price. Then when the earnings can't match the estimates that the institutions fabricated, the stock drops and the fat boys win again.
Rinse and repeat because people are so dumb after decades of this scam gullible people still scratching their heads.
But if you are going long long long on monopolist tech stocks you can't really lose, especially if they buy up all the competition.
