ChainCatcher 消息，知名投资者段永平在雪球发文并配图披露其美光科技（MU）相关持仓。他表示，买短期期权的人大概率是在赌，卖的人很可能只是保险公司或开了家赌场，关键在于靠规矩控制赔率；卖 Put 靠的是对生意的理解（即概率或赢面）。他强调不要想每一把都赢，但不懂的东西一定不要碰。
图片显示其近期交易记录包括：多次持有的美光 8 月到期 870 美元 Put 期权到期作废；8 月 11 日卖出 100 张 8 月 26 日到期 870 美元 Call 期权，成交价 37.55 美元，获得约 37.55 万美元权利金；8 月 10 日因 Put 被行权，获配买入 1 万股美光股票，成本价 870 美元，总金额 870 万美元。
