It is known that those stocks that enter the 'S&P 500' have increased in their stock price by about 20% and Tesla will definitely take a place in this. My #1 speculation on tesla will be that it will exceed its all-time high which is 500(might be pre-market) on open there will be high highs and lows but overall my #2 predictions are that it will reach its new support and resistance around 440 USD to 480 USD.
