tw-stock-analysis

Business

Use this skill when the user needs to evaluate a Taiwan stock, compare TWSE/TPEx-listed companies, assess valuation, or review earnings — even if they say 'should I buy this stock', 'analyze 台積電', 'is this stock overvalued', or 'compare these two Taiwan companies'.

Taiwan Stock Fundamental Analysis

Framework

IRON LAW: Valuation Is Relative — Compare to Peers and History

A P/E of 20 is cheap for a growth tech stock but expensive for a mature
utility. ALWAYS compare to: (1) industry peers, (2) the stock's own
historical range, and (3) the broader market (TAIEX average P/E ~14-18).
A single number in isolation is meaningless.

Analysis Steps

Phase 1: Business Understanding

What does the company do? Which industry/sector?
Who are the main competitors?
What drives revenue? (products, segments, geographies)

Phase 2: Financial Health

Revenue trend (monthly data unique to Taiwan market — check 月營收)
Profitability: EPS trend, operating margin trend
Balance sheet: D/E ratio, current ratio, cash position
Cash flow: operating CF positive? Free cash flow trend?

Phase 3: Valuation

P/E vs peers, vs own 5-year range, vs TAIEX average
P/B vs peers (especially for asset-heavy industries)
Dividend yield vs peers and vs Taiwan 10-year bond yield (~1.5%)

Phase 4: Growth & Risk

Revenue growth rate vs industry
Capex plans (MOPS announcements)
Concentration risk (customer, product, geography)
Regulatory and geopolitical risks

Taiwan Market Specifics

Feature	Detail
Monthly revenue disclosure	Listed companies report monthly revenue by the 10th — unique to Taiwan, provides more timely data than quarterly reports
Dividend culture	Taiwan investors heavily favor dividend stocks. High-yield stocks trade at a premium.
Ex-dividend price adjustment	Taiwan stocks drop by the dividend amount on ex-date. This is normal, not a loss.
Day trading tax	Securities transaction tax: 0.3% (0.15% for day trades). Factor into short-term trading costs.
Foreign investor influence	外資 (foreign institutional investors) buying/selling data is public and significantly moves stock prices. Monitor 三大法人 (three institutional investors) data.

Gotchas

EPS can be distorted by one-time items: Check if EPS includes asset sales, legal settlements, or write-offs. Use "recurring EPS" (本業 EPS) for trend analysis.
Monthly revenue ≠ profitability: A company growing revenue 30% might have declining margins. Revenue growth without margin analysis is incomplete.
Dividend yield trap: A stock yielding 8% may be cheap for a reason (declining business, unsustainable payout). Check if the payout ratio > 80% — that may not be sustainable.
Taiwan stock prices adjust for dividends: Unlike US stocks, Taiwan stock prices drop by the cash dividend amount on ex-date. A NT$100 stock paying NT$5 opens at NT$95. This is not a loss — you received NT$5 in cash.
This is educational analysis, not investment advice: All investment carries risk. Past performance does not predict future results. Consult a licensed financial advisor.
