NVDA appears to be topping for a 3rd time over the past 16 to 20 years in concert with the tops of the key markets in 2000, 2008, and 2016. Buyers at this point are hoping that buyers down the road will be willing to buy the stock at a higher price. Right now there is a slow grind up. When sentiment changes to the negative the existing holders will find it difficult to find buyers willing to take the stock as it goes down in price.
