We can see how the Google (Alphabet) chart has broken down
A 50% Fib retracement could take it down to $2000 and thats a further 22% fall from here. After having fallen 13% from its peak, its share price is still 52% higher than at the start of 2021, which shows how overextended it is.
Now I invite you to set to All View to see its LT chart, draw the uptrend line and you can see that the price is about $1420 where it could touch the line which happens to be its major support in Sept20. And you will see why a 45-50% price retracement from here is not all far fetched.
Which means that if this is the beginning of a more protracted crash, this is possibly just the beginning.
This time around, we may not see a 20% crash in a single day (although we saw that in Netflix) , but could be death by a thousand cuts. Expect a rebound in early part of next week which most likely would be sold down again thereafter.
