a*******e 发帖数: 3897 | 1 本蝌蚪去年开始试验买leaps call,运气不错,虽然经过大跌,up to date还是有翻倍
的浮盈,现在觉得季报将近,由于疫情影响展望可能会不好,想卖掉锁利,等股价跌了
再捞回来。现在设想了一个strategy,卖出现在的option,再用成本+收益买strike更
高也就是价格更低的option,同时expiration date也延长到2年后。请教版上大牛,这
种做法可以扩大收益吗?
比如说,原来买了50手strike 30的call,现在卖掉,再买strike 40的call,由于价格
差,可能可以买到60手,那么如果股票能保持继续增长的话,增持option是否会增加收
益?还是说,如果在同一个股票上操作的话,不另外增加投资,不管怎么折腾,收益还
是一样的?经过观察,我发现option的delta是会随着股价的增长而增加的,我买入时
候是0.8左右,现在长到了0.95,所以就想再买入0.8 delta的期权看能不能继续增长。
本蝌蚪脑子笨,也没经验,想不明白,请大牛们不吝指教! | a*******e 发帖数: 3897 | | E***r 发帖数: 1037 | 3 Rolling up your call strike with the same number of contracts takes some
profit and reduces your delta exposure. But if you size up your contracts
at the higher strike, you may conduct "pyramiding"; when you pyramid to the
same total delta, if the underlying price continues to trend up, your
position will usually get more delta exposure than what your original
position would get.
Risk-free pyramiding may be achieved if your new position costs less than
the realized profits of your roll-up. It is easier to achieve with short-
term options than leaps. If such risk-free pyramiding cannot be achieved
with the options of your choice, a rule of thumb is to not let your new
position expose to more risk than your original position.

您说的delta exposure没看明白,查了一下,是不是指由于期权的delta升高,它的
time value就降低了,为了避免丧失time value,应该roll up到更高的strike以降低
delta exposure?
