Is It Too Late To Consider SK hynix After Its 218% AI Driven Surge?

Simply Wall St
  • If you are wondering whether SK hynix is still good value after its massive run up, you are not alone and this article will walk through what the current price is really baking in.
  • The stock has cooled a little in the last month, slipping about 6.0%, but that comes after a stunning 217.8% gain year to date and roughly 229.0% over the last year, which completely changes how we need to think about upside and risk.
  • Recent momentum has been driven by the global rush into AI related memory demand, with investors betting that SK hynix will remain a key supplier of high bandwidth memory chips used in leading edge data centers. In addition, optimism around a multi year upcycle in DRAM and NAND pricing has pushed sentiment from cautious to outright bullish, helping to justify, at least in the market's eyes, the rapid rerating in the share price.
  • Even after that rally, our valuation framework gives SK hynix a 5/6 valuation score, suggesting it still screens as undervalued on most checks. Next, we will unpack what different valuation approaches say about the stock, before finishing with a more nuanced way to think about its true worth.

SK hynix delivered 229.0% returns over the last year. See how this stacks up to the rest of the Semiconductor industry.

Approach 1: SK hynix Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model estimates what a business is worth by projecting the cash it can generate in the future and then discounting those cash flows back to today in today’s ₩ terms.

For SK hynix, the latest twelve month free cash flow is around ₩20.9 Trillion. Analyst forecasts and subsequent extrapolations used in the 2 Stage Free Cash Flow to Equity model point to free cash flow rising to roughly ₩94.2 Trillion by 2035, with the steepest growth expected over the next few years as AI driven memory demand lifts earnings.

When all projected cash flows are discounted back, the model arrives at an intrinsic value of about ₩1,182,969 per share. That implies the shares trade at roughly a 54.0% discount to this estimate. This suggests the market is still cautious about how durable this cash flow upswing will be.

On balance, the DCF view is that investors are getting SK hynix growth at a material markdown relative to its modeled long term cash generating power.

Approach 2: SK hynix Price vs Earnings

For profitable companies like SK hynix, the price to earnings, or PE, multiple is a useful shorthand for how much investors are willing to pay today for each unit of current earnings. A higher PE usually reflects stronger growth expectations or lower perceived risk, while a lower PE can signal slower growth, more uncertainty, or a market that is still skeptical about how sustainable profits will be.

SK hynix currently trades on a PE of about 10.52x, which is well below both the global Semiconductor industry average of around 16.52x and the peer average of roughly 33.10x. Simply Wall St also calculates a proprietary Fair Ratio of 30.03x for SK hynix, which is the PE that might be expected given its earnings growth outlook, profit margins, size, industry positioning and risk profile.

This Fair Ratio offers a more tailored benchmark than simple peer or industry comparisons, because it explicitly adjusts for how fast SK hynix is growing and how risky its earnings stream appears. With the current PE of 10.52x sitting far below the 30.03x Fair Ratio, the multiple based view points to SK hynix being materially undervalued.
