SK Hynix (KOSE:A000660) Stock Still Looks Cheap After A Huge Run

Simply Wall St·09/11/2026 22:29:19
Listen to the news

SK hynix has delivered extremely strong returns over the past few years, yet the broader valuation checks still suggest the stock screens as relatively inexpensive rather than stretched. For anyone looking at the recent gains and wondering what is already priced in, the numbers point to a company whose share price has risen significantly while traditional value metrics still appear supportive.

  • Over the past 5 years, SK hynix has returned about 16.9x, which places recent gains in the context of an extended and very powerful run.
  • Expectations around demand for SK hynix memory products can support earnings power, while any downturn in pricing or capacity utilisation may pressure profitability and weigh on the valuation.
  • The broader checks lean toward inexpensive, with SK hynix screening as undervalued on most measures and earning a high value score of 5 that indicates a discount relative to key fundamentals.

The issue now is whether SK hynix shares still offer a reasonable margin of safety after such strong returns or whether the current price already reflects most of the upside that the fundamentals can support.

Is SK hynix Still Cheap on Earnings?

The P/E ratio suits SK hynix because earnings are a key driver of how investors usually think about memory producers. On this measure, the stock trades on about 8.2x earnings, which is roughly half the semiconductor industry average of 15.6x and far below a peer group closer to 42.9x. For a reader comparing options within the chip space, that is a wide gap in how the market is pricing each unit of current profit.

The fair P/E ratio estimated for SK hynix is about 42.5x. That is much higher than the current 8.2x. This implies the shares change hands at a steep discount to what this model suggests could be reasonable given factors such as sector, size and risk profile. This does not tell you how the share price will move next, but it does show that on earnings alone, the valuation still leans conservative.

On a straight P/E comparison, SK hynix appears undervalued relative to both its tailored fair multiple and typical semiconductor peers.

The Bottom Line

On the current market-multiple view, SK hynix still screens as undervalued, even after a very sharp share price move that would usually compress the margin of safety. The wide gap between its P/E and typical semiconductor benchmarks leaves room for either a catch up in the valuation or a reset in expectations if memory conditions soften. The crux now is whether earnings power in AI linked memory products holds up well enough for that discount to close, or whether geopolitical and industry cycle risks prove that the lower multiple is warranted.
