Warren Buffett once said: Buying one-sided expiry warrants is no different from gambling.

Here, Citi did not specify "a certain indicator," but it's not hard to analyze the main force behind this all-in bet (I think it's mostly individual investors). Including South Korea (leveraged ETFs), it feels like a casino. Although I'm also on board and hope it continues, the risk impact cannot be ignored. Leveraged financing should definitely be avoided.
