Looking at it in the long run, this is a trader known for patience: its previously completed large trades were all long positions mapped from long-hold U.S. stock trades—Micron for about 45 days, Marvell for about 29 days, and Cerebras for about 39 days—accumulating net profits of about $494,500. The same kind of patience was once a source of its profits, but on Hynix it is also digging deeper the longer it withstands…
