Should I high and buy low for Tesla at this point of time?

As i couldn't find a convincing reason why the price has suddenly risen so much in the recent weeks except the fact that Tesla has entered the S&P 500.

Is there a good chance that the stocks price will fall back a reasonable amount once the hype is gone when S&P 500 inclusion happened?

I am thinking of waiting until next thurs/fri or sell my shares once it hit $750-$780.

And hope the market crash the following week.
Am I too naive to think that way?
