Unless NVDA closes clearly above 810 today a major correction seems very likely. Yesterday, a 33 bars (49 days) upwards trend line had been broken and prices returned into the inside of the long term channel. Although RSI cooled down a little, the stock still remains overbought. In my opinion, what we see here is the beginning of a secondary trend against the primary uptrend.
Possible price targets / turnaround points are at the previous trend lines: ~680 ~650 ~620
