Michael Johnson is CEO & Chairman at HERBALIFE NUTRITION LTD. (HLF). They have made 21 open-market trades across 2 companies since 2007, most recently 2026-05-28.
Unrated. We grade insiders only on stock they chose to buy on the open market. Grants, option exercises and vesting say nothing about timing, so they don't count — which is why someone can file often and still have no grade. It isn't a bad sign: unrated buys beat every graded tier below A.
5 open-market purchases totalling $2.8M since 2019, against 16 sales. Across 5 scored buys the stock is up 32.5% at ninety days, and 28.0 points ahead of the S&P over the same stretch.
