Amazon results are really good, but many investor speculated about Amazon, was buying heavily on the day of result announcements. That may make a fall of 3% or 4% down, but not a real fall. If the results were bad, it would have fallen 10% or 12%.
Another indication, look at Finviz (Picture attached) indicates Multiple Tops. Normally, when such things happen, it is bound to fall. Last one year, I have seen one rare exception for this double top or multiple top pattern.
This was shown even on Results day morning. Amzn may go down and up, but long term the stock is going to go up. Same thing happened with FB and GOOGL.
Since Amazon results are good, I bought them now. It is unlikely to touch $710. I bought GOOGL and FB too after their fall.
