Frequently asked
What is United Microelectronics Corp. ADR's fair value?+
Intrinsiqq's two-stage DCF estimates an intrinsic value of about TWD 615.75 per share for UMC, projecting its recent free cash flow forward with a growth rate that fades toward a long-run rate and discounting it back to today. Applying a 25% margin of safety gives a more conservative fair-value entry around TWD 461.81. At today's TWD 18.53, that puts the stock about 3,223.0% below estimated intrinsic value. The result is sensitive to the growth and discount-rate inputs, so it is best to run conservative, base and optimistic cases. You can adjust all of them yourself with the sliders on the DCF tab.
Is United Microelectronics Corp. ADR a high-quality business?+
United Microelectronics Corp. ADR scores 42 out of 100 on Intrinsiqq's quality score, a weighted blend of 8 metrics each scored 0 to 100, which makes it a mixed business on these measures. Recent fundamentals include a 20.1% operating margin and a 8.3% return on invested capital. The score weighs revenue and free-cash-flow growth, operating margins, return on invested capital, share-count change, and balance-sheet strength, all computed from company filings, not opinion. Because valuation only means something relative to quality, the full metric-by-metric breakdown is on the quality scorecard.
Is United Microelectronics Corp. ADR a good stock to buy right now?+
That depends on valuation and quality together, not either alone. UMC currently trades below its estimated intrinsic value and scores 42/100 on quality (mixed). A cheap price is only a bargain if the business is durable, and a premium can be justified by genuine quality, so the two questions, "is it cheap?" and "is it good?", only make sense side by side. Read the valuation against the quality scorecard, run the DCF on your own assumptions, and decide for yourself. This is analysis from company filings, not investment advice.
