Samsung Electronics shares have taken investors on a wild ride over the past year, climbing from a July 9, 2025, low of 60,200 won ($40.12) to a June 19 peak of 374,500 won — a whopping 522 percent gain.
But a closer look shows just how dizzying the swings have been. Last week alone, the stock moved down 4.86 percent, up 3.41 percent, down 5.84 percent, down 9.06 percent and up 8.22 percent over five straight trading days.
This week brought another bout of whiplash around Tuesday's preliminary second-quarter earnings release, with the shares moving up 2.75 percent, down 6.92 percent and down 6.25 percent over three consecutive sessions.
The swings are raising a bigger question for investors: Why are shares of Korea's most valuable company trading less like a national champion and more like a momentum bet?
