Options trading uses Greeks to quantify risk. Delta = price sensitivity. Gamma = delta change. Vega = volatility sensitivity. Theta = time decay. Strategies: covered calls (income), spreads (directional), straddles (volatility). Learning curve: 4-6 weeks for basics, 8+ weeks for mastery. Professional traders earn $150k-500k+ (salary + trading profits). Requires discipline, risk management, and quantitative mindset. 90% of retail traders lose money; 10% succeed.

什麼是 Options Strategies Greeks

Options trading uses mathematical models (Greeks) to quantify risk and opportunity. Greeks: Delta (price sensitivity), Gamma (delta change), Vega (volatility sensitivity), Theta (time decay), Rho (interest rate sensitivity). Strategies: covered calls (sell upside for income), spreads (vertical, iron condor, calendar), straddles (bet on volatility), collars (downside protection). Professional traders use Greeks to size positions, hedge risk, and optimize returns.

❓ 常見問題

What does 'delta' mean and why does it matter?
Delta = how much option price changes if stock moves $1. Delta 0.5 = option moves $0.50 if stock moves $1. Use delta to hedge: own 100 shares (delta 100), sell call (delta -30) = net delta 70 (partial hedge).
Why do options lose value over time?
Theta (time decay). As expiration approaches, option loses extrinsic value. Theta accelerates near expiration. Sellers benefit (earn theta). Buyers lose. Understanding theta = key to strategy.
What's the difference between covered calls and naked calls?
Covered call = own stock, sell call. Max loss = stock price. Naked call = no stock, sell call. Max loss = unlimited. Covered = safe, naked = risky (margin accounts only, usually forbidden).
How do I know if an option is overpriced?
Use implied volatility (IV). If IV > historical volatility, option expensive (sell). If IV < HV, option cheap (buy). IV tells you what market expects.
Can I make money if stock doesn't move?
Yes, if you're short volatility (sell options). If stock stays flat, options lose value (theta decay). You profit. Opposite: if you're long volatility (buy options) and stock doesn't move, you lose.
