South Korea's stock market has been the world's hottest over the past year, with the Kospi Index surging 165% on the back of the country’s two semiconductor powerhouses, Samsung Electronics and SK Hynix. This new territory "is creating a lot of issues within Korea," Stanford sociologist Gi-Wook Shin, director of APARC's Korea Program, tells Barron's.

The magazine's story – South Korea Has a Chip Conundrum – Huge Profits and a Serious Selloff – highlights how the two companies' mind-boggling earnings and bonuses have opened something of a Pandora’s box of social and economic friction. For example, disgruntled employees at less-privileged Samsung divisions are leaving their union and trying to form a new one, Shin says.

The story notes, however, that these controversies "might look like a mild kerfuffle if the chip makers’ shares keep falling back to earth." Despite a 150% year-to-date gain, Samsung shares dropped 16% last week amid foreign investor sales and leveraged local buying.
