SanDisk’s operational thinking: today, when the Korean stock market opened, it got slashed again—so Hynix estimates that it will drag SanDisk along and continue its momentum downward. At the open, open a short position with half the usual size to hedge against downside. If the price moves up after the open, close the short position. If, over the next few days, the old position can retrace back to 1300, then sell half and reverse to open a short position with the same size, leaving the other half as the base position—because it’s expected that in the near term it will trade in a range between 1150 and 1300 for a while. It’s also possible to return to 1500, but the probability is lower, and the time required would be much longer.
