It may seem contradictory, since joining an important market index is a very good thing, requiring funds to adjust their holdings. In Tesla’s case, I see at least USD 8 billion would have to be invested through them. I tend to doubt this will automatically lead to a massive increase in valuation. Index funds may already have positions based on a variety of investment vehicles, such as options that can be turned into shares without any relevant influence on the price. Perhaps out of pure contrariness, the stock could turn sour when things are looking their best because analysts, investors and the media see only rising prices, completely ignoring the risks.
FuelCell Energy’s quarterly results weren’t the reason for the year-end price surge from around USD 2 to over USD 11. At times, more than 200 million trades were concluded in one day, which exceeds the total shares outstanding. I believe we’re witnessing the impact of high-frequency or day trades or swarm-like investor activity via, e.g., Robinhood. Right before the rally, Heights Capital Management reported the purchase of 19 million FuelCell shares, giving the private equity firm a 6.7 percent stake in the fuel cell business.
