FA: Tesla has been parabolic the past few weeks and has formed several new highs; the release of the earnings is bound to create volatility both ways.
Option traders are using a straddle strategy where they are predicting a move of $200 in either direction with the use of the SAP volatility INDEX (VIX) which we can see sometimes does correlate with the volatility of Tesla.
Bulls expect the S&P 500 inclusion for Tesla to be confirmed as they have reported profits which may lead to high volatility.
TA:
News could already be factored into the current price and thus can expect a retracement at market open.
If Tesla breaks above the resistance for the previous high, then we can expect it to form new ATH if not then we can expect it to retrace and perhaps fill the lower gaps although unlikely.
