Assessing Semiconductor Manufacturing International after recent share price weakness

Semiconductor Manufacturing International (SEHK:981) has come under pressure recently, with the share price showing a 3.5% decline over the past day and a 16.7% drop over the past month. For investors, this invites a fresh look at how the current valuation aligns with the company’s scale and earnings profile.

See our latest analysis for Semiconductor Manufacturing International.

At the current share price of HK$51.0, the recent 16.7% 30 day share price decline and 32.1% year to date share price drop contrast with a 13.2% 1 year total shareholder return and 127.2% 3 year total shareholder return. This suggests momentum has cooled after a strong multi year run.

If this pullback has you rethinking where growth in chips and related hardware could come from next, it may be worth scanning other AI infrastructure names using the Simply Wall St screener for 36 AI infrastructure stocks

So with revenue of CN¥67,323.2m, net income of CN¥5,040.7m and a HK$514.9b market cap now paired with sharp recent share price weakness, are you looking at an undervalued chip foundry or a market that is already pricing in future growth?

Most Popular Narrative: 34.4% Undervalued

With Semiconductor Manufacturing International last closing at HK$51.0 against a narrative fair value of HK$77.69, the most followed view sees meaningful upside and leans on detailed growth, margin and valuation assumptions to justify it.

SMIC's aggressive expansion of wafer capacity, particularly in 8-inch and 12-inch nodes, positions the company to capture rising demand from domestic downstream markets such as automotive and analog, supported by strong volume growth and high utilization rates; this supports long-term revenue growth and stabilization of gross margins.

Read the complete narrative.

Curious what kind of revenue build, margin lift and earnings multiple are baked into that HK$77.69 figure? The narrative leans on faster earnings growth than the wider Hong Kong market, richer profitability assumptions and a premium P/E several years out, all tied together using an 11.85% discount rate and specific share count expectations.

Result: Fair Value of HK$77.69 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, these assumptions could unravel if pricing pressure persists despite volume growth, or if SMIC's heavy reliance on Chinese demand leads to more volatile revenue and earnings.

Another way to look at valuation

The narrative model points to undervaluation, but the simple earnings multiple tells a different story. At a P/E of 71.1x, Semiconductor Manufacturing International trades at a much richer level than the Asian semiconductor group on 39.6x and its own fair ratio of 33.8x. That gap suggests the market is already baking in a lot of optimism. How comfortable are you with that kind of valuation risk?
