Longtime investor Ron Barron believes investors are being given a once-in-a-lifetime buying opportunity after stocks plunged into a bear market on fears of a recession. “I hope you can convince one or many people to tell your viewers that this is a huge once-in-a-generation buying opportunity,” Barron said in an email sent to CNBC’s Becky Kwik and Joe Kern. “A huge opportunity after the June 2022 crash (also June 2020)!” The S&P 500 plunged into a bear market earlier this week as recession fears deepened in conjunction with the most aggressive Fed rate hike since 1994. The stock index is now nearly 24% off its all-time high in January. All of its 11 sectors are at least 15% lower than their recent highs. The CEO of Baron Capital said that the stock market has progressed only modestly over the past two decades even though the economic expansion has been impressive thanks to innovative technology. Barron wrote, “I was talking to my sons last night. They’ve been in our business for about twenty years. Since graduating from college with a two-year break to get an MBA.” “Since then the wars…the internet bubble burst…the financial panic of 08-09..the covid pandemic…commodity inflation…and the modest progress in the stock market.a little more than doubled.22 years. It was physical and accelerating spurred by technology and biology!” Barron, whose funds owned more than 4.6 million shares in Tesla early last year, said he told his sons that the opportunity now is as big as it was when he started his company 40 years ago, and that growth stocks are poised to enjoy huge gains . “I told them they now had the same opportunity that I had when I founded Barron Capital on March 16, 1982 and that the Dow was 880! After 16 years of no progress in market averages,” Barron said. “This is especially the case now because we now have investments in incredible growth companies like Tesla, SpaceX and many, many, many other companies.” Baron Capital managed approximately $49 billion in assets as of March 31.
