Johnny Wu of xETFs talks about the firm's Korea AI Semiconductor ETF (KSMH) and ways it is used to offer international exposure to the AI memory trade. As Johnny says, the firm chose South Korea because of its positioning "in the center" of the industry. He talks about how Samsung's and SK Hynix's (SKHY) meteoric rise inspired the firm to find companies they believes have potential to turn $10 billion market caps into $1 trillion.
