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.

- 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%)

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.
