Group 1 - The core concept of options leverage is derived from the significant disparity between the value of the underlying asset and the premium paid for the option, allowing investors to control a larger asset value with a smaller amount of capital [1][4] - Options leverage is fundamentally different from futures leverage, as options provide a right without the obligation to execute, leading to asymmetric risk and reward profiles [2][3] - The nominal leverage ratio is calculated as the ratio of the underlying asset price to the option premium, indicating how much asset value can be controlled per unit of premium paid [5][6] Group 2 - The actual leverage ratio incorporates Delta, which measures the sensitivity of the option price to changes in the underlying asset price, providing a more accurate reflection of the potential returns [6][8] - Factors affecting options leverage include whether the option is in-the-money or out-of-the-money, the time until expiration, and market volatility expectations [9][10][11] - In-the-money options have lower nominal leverage but higher Delta, while out-of-the-money options have higher nominal leverage but lower Delta, affecting their sensitivity to price changes [9][10] Group 3 - Investors can strategically use options leverage by selecting in-the-money options for better price tracking and moderate expiration timelines to balance time decay and leverage efficiency [13][15] - The choice of strike price and expiration date reflects the investor's conviction and risk tolerance, with deeper in-the-money options being suitable for long-term bullish or bearish views [14][15] - Market expectations of volatility influence option premiums and leverage effects, with higher volatility leading to increased premiums and reduced leverage efficiency [12][11]

2026 年 01 月 29 日 期权杠杆科普：期权的杠杆从哪里 来？ ——白话期权系列之一 相关研究 证券分析师 方思齐 A0230525090002 fangsq@swsresearch.com 邓虎 A0230520070003 denghu@swsresearch.com 联系人 方思齐 A0230525090002 fangsq@swsresearch.com 名义杠杆倍数：名义杠杆倍数 = 标的资产价格 ÷ 权利金 该指标直观反映了单位权利金所能控制的标的资产市值，但未考虑期权价格与标的资产 价格变动的实际关联性。 实际杠杆倍数：实际杠杆倍数 = Delta × 名义杠杆 此处的关键在于 Delta。Delta 可理解为期权价格相对于标的资产价格变动的敏感系数。 在名义杠杆的基础上引入 Delta，能够更真实地反映期权收益相对于标的资产价格变动的 实际放大倍数，即实际杠杆。 ⚫ 期权的杠杆变化： 期权虚实程度：虚值期权的名义杠杆通常较高，但由于其行权价与标的资产当前价格存在 较大差距，Delta 值较小，因此在计算实际杠杆（Delta × 名义杠杆）时，较低的 Delta 会部分抵消高名义杠杆的效 ...
