NVDA has been trending down since before their earnings call. Even though the drop might not be significant, I am using trend lines and Fibonacci levels to determine a minimal drop. The most likely drop that conforms with the trends and Fib retracement levels is at least to 160.82. If it goes beneath this level and below the trendline, A more significant drop would be in the making. It is possible the stock could drop further to 147.07. Anything beyond this should be (but probably won't) a major red flag for traders.
