Bill Ackman has ditched his stake in Netflix after losing more than $430 million on his investment in less than three months. Mr Ackman’s Pershing Square Capital Management said on Wednesday it had sold its Netflix holdings after the streaming TV pioneer reported an unexpected drop in subscribers in the first quarter and projected an even steeper decline in the current one. Netflix shares tumbled 35 per cent to $226.19 at the close in New York, making it the worst performer in the S&P 500 this year. Mr Ackman became one of Netflix’s 20 largest holders this year, buying after the stock had already begun to dip over concerns about its subscriber base. Based on price before Mr Ackman disclosed his stake on January 26, his fund lost about $435m on his more than 3.1 million-share position. His holdings in the company would have been worth about $700m as of Wednesday’s close. A representative for Pershing Square declined to comment on the size of the loss. Netflix shares climbed as the coronavirus pandemic took hold and peaked in November, more than doubling from the start of 2020. With Wednesday’s plunge, the stock is now down 62 per cent this year. Buying after the stock dipped, Mr Ackman said in a letter to investors in January that “the opportunity to acquire Netflix at an attractive valuation emerged when investors reacted negatively to the recent quarter’s subscriber growth and management’s short-term guidance”. He cited the company’s favourable characteristics, including its subscription-based business model and management team. Pershing’s Netflix share purchases were funded by the unwinding of the “substantial majority” of an interest-rate hedge, which generated proceeds of $1.25 billion, Mr Ackman said at the time. In his letter to shareholders on Wednesday, Mr Ackman said his fund overall is down 2 per cent in 2022. He said he has learned from past mistakes to exit bad bets early. He said he will redeploy the money from the Netflix stake sale to other opportunities. Netflix isn’t the first big loss for the billionaire investor. Mr Ackman admitted defeat in a short position in Herbalife after a fight with Carl Icahn, and banked a $4bn loss on his misguided bet on Valeant Pharmaceuticals International. He has also had trouble finding a target for his blank-cheque company, Pershing Square Tontine Holdings, which raised $4bn in an initial public offering in July 2020 and hasn’t yet completed a merger transaction. Mr Ackman has, however, managed to improve his fortunes in recent years, including back-to-back record years for returns at his New York-based hedge fund in 2019 and 2020. Netflix, the “N” in tech’s so-called FAANG stocks that drove much of the market euphoria of the past few years, is now that group’s fallen angel. The company that invented the idea of binge-watching favourites, including <i>Squid Game</i> and <i>Bridgerton,</i> has tossed out its old playbook and is searching for new ways to boost revenue. It is considering offering an ad-supported version, while also cracking down on customers who share their passwords with friends and family, both signs the easy days of subscriber growth are behind it.
