Kroger’s biggest known investor is Warren Buffet, with his hedge fund Berkshire Hathaway buying shares in the supermarket chain’s operations just last year. Considering the immense weight Buffet carries in the stock trading world, a number of others followed suit, including Tobam, which is a Paris-based hedge fund that’s worth $7.2 billion. Tobam first bought shares back in 2016, but added another 166,581 shares, giving them a total of 1.5 million shares that is now worth over $50 million and giving them a 3.3% equity portfolio.
