Leo Koguan

The Elon Musk “fanboy” claims to be the biggest Tesla investor and option trader in the world. Koguan says he had even more shares in early 2020 but nearly lost them all amid early-pandemic market chaos. Instead he sold the rest of his holdings, including shares of Baidu and Nvidia, to buy longterm Tesla call options. “I believe in green energy,” he tells Forbes. An Indonesian native with degrees from Columbia and New York Law School, Koguan is also founder and chairman of $12.3 billion (sales) IT provider SHI International, which his ex-wife Thai Lee (No. 252) runs as CEO.
