There's a lot of speculation NVDA is overextended and, well I can see their point.
But maybe through the last years we have had waves 1 and 2 of Elliot. Which would mean we're in wave 3 and in wave 3 "Overextended" does not really exist. A super consistent trend is what is the norm.
Wave 3's are incredibly easy trends to follow but a lot of the time in wave 3 people spend more time trying to call the top than follow the trend.
If we're in the Elliot waves, NVDA has a lot more pain to bring to those who want to bet against it.
