Summary by Directory 1. On - site Option Strategies - Single - leg trading, which involves directly buying or selling call or put options, is the cornerstone of complex trading. Buying call options is suitable for bullish markets with limited cost and unlimited theoretical returns, while buying put options is for bearish markets. Selling options aims to earn stable cash flow but bears the risk of exercise. The covered call strategy, which combines with the underlying asset, is a relatively stable return - enhancement strategy [10]. - When investors have more refined views on the market, they can use combination strategies. Directional combinations like bull spreads are suitable for moderately bullish markets, and bear spreads for moderately bearish markets. Butterfly spreads are used for markets with narrow - range fluctuations. Volatility strategies such as straddle combinations are for markets with significant but uncertain - direction fluctuations. Calendar spreads use the time - value difference between different - maturity contracts and are suitable for stable or moderately volatile markets [11][13] 2. Off - site Option Strategies - Off - site options are customized agreements between financial institutions and customers to meet special risk - management needs. The "Snowball" product is well - known. Investors can get high coupons in a moderately rising or volatile market but face principal - loss risks in a sharp - falling market. The Dynamic Coupon Note (DCN) is a more flexible "Snowball - like" product. It optimizes cash flow and meets regulatory requirements but still has risks, such as one - time principal loss at maturity and dependence on the futures discount environment [15][16]
