Table of contents
For Taiwan investors, U.S. stocks differ from Taiwan stocks in much more than trading time. Exchanges, settlement, extended hours, filings, currency exposure, and broker access all work differently.
What are NYSE and Nasdaq?
They are two major U.S. stock markets. Investors usually identify securities by ticker symbols rather than translated company names.
Regular U.S. trading hours
NYSE and Nasdaq regular sessions run 9:30 a.m.–4:00 p.m. Eastern Time, which shifts by one hour in Taiwan depending on daylight saving.
Extended hours are different
Pre-market and after-hours trading can have lower liquidity, wider spreads, and broker-specific order restrictions.
Most applicable U.S. securities now settle T+1
Standard settlement is one business day after trade date, unlike Taiwan's common T+2 cycle.
No universal ±10% daily limit
U.S. markets rely on price bands, stock-specific halts, and market-wide circuit breakers instead.
SEC EDGAR is a primary research source
Use 10-K for annual information, 10-Q for quarterly updates, and 8-K for material current events.
Currency affects TWD returns
A USD gain is not automatically the same as the return after converting back to TWD.
Broker capabilities vary
Single-share or fractional orders, extended hours, recurring investing, fees, FX, and tax documents differ by broker.
Common beginner mistakes
Equating low share price with cheap valuation, chasing hot tickers, ignoring FX and taxes, using aggressive orders in thin extended hours, and relying only on headlines.
A practical research flow
Confirm the company and ticker, review SEC filings, industry, financials, valuation, and risks, then decide whether the stock fits your portfolio rather than starting from popularity.
