Value investor Duan Yongping commented on Micron Technology (MU) options trading, comparing selling put options to running a casino. 'Those who buy short-term options are mostly gambling, while sellers are likely just insurance companies, or you could say sellers are just opening a casino,' Duan said.

He stressed that running a casino relies on controlling odds through rules, and selling puts depends on understanding the business—essentially a grasp of probabilities or winning chances. Duan advised investors not to expect to win every trade but never to touch things they don't understand.

His remarks align with his long-standing value investing philosophy, emphasizing deep understanding of underlying asset fundamentals rather than speculation.

Micron Technology, a global leader in memory chips, has seen significant price volatility recently, drawing increased attention to its high-beta characteristics among investors.
