Retail investors are showing enthusiasm for SK Hynix's American Depositary Receipt (ADR) listing on Nasdaq, driven by the potential for high-leverage options trading. According to Serenity, known as the "White-haired Stock God," the excitement is less about direct stock investment and more about the opportunities for speculative call option trading that the listing provides. This sentiment highlights a growing trend among retail investors to seek high-risk, high-reward trading strategies in the options market.
