NVIDIA Corporation (NASDAQ:NVDA) shareholders have witnessed a decrease in hedge fund sentiment during third quarter. Some hedge fund managers might have sensed the looming demand declines and bolted out. Nevertheless, NVDA was still the 67th most popular stock among hedge funds at the end of September (check out the list of 30 most popular stocks among hedge funds now). Today, NVIDIA shares plunged more than 19%. This is a stock that was trading at $12 six years ago and its fans were arguing that Nvidia should replace Netflix, Inc. (NFLX) in the FAANG group. Here is how FT explains the sharp decline: "Cryptocurrency miner demand for Nvidia chips raised revenue last year. But the decision to stock up on the cards was a bad one. As prices for cryptocurrencies such as bitcoin fell, so did demand. Nvidia’s core gaming unit, which sold the cards used for crypto-mining, still makes up the bulk of revenue. The drop in demand means total revenue for the third quarter looks disappointing at $3.8bn. The 21 per cent increase on last year is puny against the usual 50 per cent plus quarterly growth that has powered the stock price. More worrying is a 7 per cent year-on-year fall in revenue forecast for the next quarter. If correct it will mark the company’s first revenue decline in more than five years. Nvidia thinks its “crypto hangover” will be temporary — and it will. New gaming chips released recently will find a bigger audience next year. It is still investing heavily in R&D too — which should mean new revenue streams to come. Operating expenses are up nearly 30 per cent on last year. A sell-off since October along with the rest of the tech sector, plus the after hours share price fall means Nvidia’s stock is trading at about 20 times expected earnings. That is still more than Intel, the world’s biggest semiconductor company, which trades at 11 times forecast earnings. The long-term potential for growth is unchanged. Nvidia has more exciting opportunities than its peers." To the average investor there are a lot of indicators stock traders can use to grade their stock investments.

Let's now take a look at hedge fund activity in other stocks similar to NVIDIA Corporation (NASDAQ:NVDA). We will take a look at TOTAL S.A. (ADR) (NYSE:TOT), Netflix, Inc. (NASDAQ:NFLX), Comcast Corporation (NASDAQ:CMCSA), and PepsiCo, Inc. (NYSE:PEP). This group of stocks' market values are similar to NVDA's market value.

That figure was $4088 million in NVDA's case. Comcast Corporation (NASDAQ:CMCSA) is the most popular stock in this table. On the other hand TOTAL S.A. (ADR) (NYSE:TOT) is the least popular one with only 13 bullish hedge fund positions. NVIDIA Corporation (NASDAQ:NVDA) is not the least popular stock in this group but hedge fund interest is still below average. This is a slightly negative signal and we'd rather spend our time researching stocks that hedge funds are piling on. In this regard CMCSA might be a better candidate to consider a long position than Nvidia. We also don't want to catch a falling knife at this point. Disclosure: None.
