SK hynix (NasdaqGS:SKHY) approved a roughly US$38b program to build new high bandwidth memory focused fabs in South Korea, a large expansion that brings long term capital commitments into sharper focus for current and potential shareholders.

Despite the expansion plans and supportive policy moves around South Korea's semiconductor sector in recent weeks, SK hynix's 30 day share price return is down 19.48%, and the year to date share price return matches that weaker tone. This signals fading momentum as investors reassess execution risk around large scale memory investments.

SK hynix now trades well below both intrinsic value estimates and the average analyst price target after the recent slide. Is the market rightly cautious about the new US$38b build out, or is the discount too harsh?

Price-to-Earnings of 6.4x: Is it justified?

On simple numbers, SK hynix looks inexpensive. The stock last closed at $135.29, while the company is described as trading at a P/E of 6.4x compared with a peer average of 59.8x and a US Semiconductor industry average of 49.5x.

The P/E ratio compares what investors pay today for each dollar of earnings. For SK hynix, a 6.4x P/E suggests the market is attaching a much lower earnings multiple than it is for similar semiconductor companies. Earnings and revenue are both reported as growing strongly.

That gap to peers is wide. If the industry trades around 50x earnings and SK hynix sits at 6.4x, the market is clearly applying a heavy discount to the stock relative to sector norms.

Result: Price-to-Earnings of 6.4x (UNDERVALUED)

However, investors still face risks around execution on the US$38b expansion, and the recent share price decline of 19.48% over 30 days could signal fragile sentiment.

Another view on SK hynix valuation

The P/E comparison paints SK hynix as inexpensive, yet the SWS DCF model presents an even stronger view. It puts fair value at $526.44 per share versus a current price of $135.29, which suggests the stock trades at a steep discount.
