今天我已經有深切的認識自己在結算日太貪了，在臨床上已經做了一些調整，讓周三參與結算的Put在40口以內，並且有能力在gamma風險太大時，直接轉倉，減少衝擊。

謝謝「管理員」的善意提醒。

Of course, at some point the piper will have to be paid, as the flip side of this short-gamma hedging that lifted stocks is what also helped to exacerbate moves in the opposite direction, as the drop in shares that started last Friday and accelerated over the next three days as the Nasdaq experienced its first correction since March, prompted market makers to undo hedges at an increasing speed, spurring more losses. The unwinding the all this gamma will be a "turbulent process," according to UBS.

想一直利用調整優化投資組合，最後也可能過度調整，一天的c+t要小於4000元，一個月8萬元的成本，扣掉成本後，還能賺8萬，就可以接受。毛利率五成。
