Value investor Duan Yongping said on October 24 on Xueqiu that he has sold covered calls on Occidental Petroleum (OXY).

He wrote, "If you don't truly understand it yourself, copying others is difficult." He added that when OXY fell to around 40 earlier, he did not add to his position, which in his view showed he did not truly understand it. "Today I sold covered calls across the board; I won’t feel bad if the calls are exercised," he said.
