SK hynix (NasdaqGS:SKHY) stock moved after reports of new tariff talks between South Korea and the U.S. on chip investment and market access. The news drew attention to the company’s AI-focused memory manufacturing plans.
Over the past month SK hynix has seen a 1 month share price return of 17.2%, building on a 7 day share price return of 9.9% and leaving the stock with a more modest year to date share price return of 5.4%. Recent gains have come as investors react to AI data center demand, the long term NVIDIA supply agreement, and the latest tariff talks, which together appear to be shifting expectations around both growth potential and future capital requirements.

SK hynix now sits between a bullish AI memory story and concerns about rising capital needs and tariff exposure. Given the recent surge in the stock, which side does the current valuation lean toward next?
Price-to-Earnings of 7.4x: Is It Justified for SK hynix?
On a simple snapshot, SK hynix trades on a P/E of 7.4x, while the stock last closed at $177. Compared with both its peers and the broader US semiconductor group, that multiple points to a market valuation that is far lower than many other chip stocks on current earnings.
The P/E multiple compares the current share price to earnings per share. For a company like SK hynix, which is tied to memory chips used in servers, mobile, PCs, and AI data centers, this measure effectively shows how much investors are paying today for each dollar of current profit. A lower P/E can sometimes reflect concerns about how durable current earnings may be, but it can also signal that the market is not assigning the same earnings value as it does for other chip companies.
Here, SK hynix is flagged as good value based on its P/E of 7.4x compared with both the peer average of 54.2x and the US semiconductor industry average of 47.2x. That is a very wide gap. For investors watching the AI chip build out and the company’s earnings profile, this big discount raises the question of whether the market is underpricing current and forecast profit, or instead building in a large margin of safety for future cycles.
The valuation gap is not just against peers; it is also large when compared to the SWS DCF model, which estimates a future cash flow value of $596.05 per share versus the current $177 share price. The SWS DCF model projects future cash flows for SK hynix, then discounts them back to today, using forecast growth in revenue and earnings as inputs. In the context of SK hynix, which has reported very strong recent earnings growth and is forecast to grow revenue and earnings faster than the wider US market, that fair value estimate implies the current price bakes in a very different outlook than the model.
Investors who want to understand how that cash flow based value is derived can go deeper into the SWS DCF framework through the Look into how the SWS DCF model arrives at its fair value.
Result: Price-to-Earnings of 7.4x (UNDERVALUED)
However, SK hynix still faces risks related to capital-intensive AI capacity buildouts and the possibility that tariff talks reshape access to key markets and customers.
