使用這個策略一段時間後,看到期權被行使只是時間問題。只要我們在行使前透過重複的溢價降低成本,就不會有太多遺憾,對吧?
當然,在期權完全行使前,還有補救措施。這是我接下來要討論的內容—延長鎖定。
2. 延長鎖定-滾動
滾動涉及購回到期合約並銷售下一期的新合約,有效地延長合約的期限以避免行使。如果幸運站在你這邊,合約將回到虧損區域,不會發生行使。
此外,只要選擇權不過度賺錢,每次滾動仍會獲得一些時間價值,這是一個額外的驚喜。因此,選擇權賣方的錯誤容忍度實際上相當高。當然,如果選擇權明顯賺錢,就不會留下時間價值,進一步滾動將毫無意義。在這種情況下,是時候止損並繼續前進。
這個策略基本上是將風險轉移到未來,儘管它無法消除股價急劇下跌的風險。為了最大程度的保險,除了買入單腿看跌期權之外,還有下一個我將討論的策略—the collar strategy.
3. Locking in Time – The Collar Strategy
That's right—locking in time, locking in position, and calmly weathering the passage of time, regardless of whether the stock price rises or falls. Specifically, it involves using the premiums received from previous covered calls to buy out-of-the-money put options, protecting the underlying stock.
This operation is an extremely conservative bullish strategy, with very low construction costs. Its main purpose is to capture a small portion of the stock's rise while avoiding significant losses in the event of a major downturn.
I really like this strategy, although I don't use it much. Mainly because, before being repeatedly beaten down by the Hong Kong stock market, I was inexplicably confident about the stock price trend. The thought of buying put options right after receiving a little interest still pains me. However, with
$騰訊控股 (00700.HK)$ dropping below 300 recently, now it's not just a pain in the heart but also in the pocket. If you really want to protect your position, this is a strategy worth mastering.
The road to investment is long and lonely, but patience and diligence will eventually be rewarded by the market.
