解释:

C is correct.

The goal of volatility trading strategy is to buy cheap volatility and sell expensive volatility and to net out the time decay associated with options portfolios.

net out就是hedge的意思? 对冲time decay导致的option价值下降的这个影响,具体对冲方法有没有要求掌握?没有印象了。

嗨,努力学习的PZer你好:


同学你好,net out就是对冲掉,或者消除掉. 对于volatility trading,我们需要掌握的是,volatility trading如何去做,四种path分别是什么。

嗨,爱思考的PZer你好:


同学你好,

Hedge Fund A’s volatility trading strategy can be implemented by following multiple paths. One path is through simple exchange-traded options. The maturity of such options typically extends to no more than two years. In terms of expiry, the longer-dated options will have more absolute exposure to volatility levels than shorter-dated options, but the shorter-dated options will exhibit more delta sensitivity to price changes.

A second, similar path is to implement the volatility trading strategy using OTC options. In this case, the tenor and strike prices of the options can be customized. The tenor of expiry dates can then be extended beyond what is available with exchange-traded options.

A third path is to use VIX futures or options on VIX futures as a way to more explicitly express a pure volatility view without the need for constant delta hedging of an equity put or call for isolating the volatility exposure.

A fourth path for implementing a volatility trading strategy would be to purchase an OTC volatility swap or a variance swap from a creditworthy counterparty. A volatility swap is a forward contract on future realized price volatility. Similarly, a variance swap is a forward contract on future realized price variance, where variance is the square of volatility. Both volatility and variance swaps provide “pure” exposure to volatility alone, unlike standardized options in which the volatility exposure depends on the price of the underlying asset and must be isolated and extracted via delta hedging.

The goof volatility trang strategy is to buy chevolatility ansell expensive volatility anto net out the time cassociatewith options portfolios. the goof volatility trang strategy根据原版书的原话是A和B(见下图讲义截图),和C没有关系,这个策略主要目的套利波动率这个衍生品的,而不是股票市场的。简单的大概说下就是volatility trang strategy是赚取sprea价差)——类似的the unrlying assets的两个期权,一个因为预期波动率将变高,是不是就会变贵对吧,一个因为预期波动率将变小,是不是会变便宜啊对吧。那就做多预期波动率变高的,做空波动率变小的,赚取之间的sprea同时去除不想要的因素(time cay)。 每天都鼓励你们的伯恩小哥哥 具体来说什么是net off cay
