For NVDA and TSLA and to a lesser extend the other five magnificient seven stocks,  there is only one way to profit from trading - buy on the dips and sell off when it turns up again. I bought at 106 sold off at 108; buy at 104 sell at 106; buy 103 sold at 106 buy at 103 and sold at 106 and last night bought at 105 and sold all at 108. At the present it is best to scalp off for profits though one could buy at the lows and hold for the longer term but nothing beats taking immediate profits in this turbulent market. As long as the markets are in high volatility, it is best to buy when it drops and sell when it turns upwards. I had profited much using this strategy for NVDA and TSLA. Good luck if you adopt this strategy.
