胡老師，請問risk management applications of option strategy的一個問題

management, option, initial, investor

one investor writes a 20 dollar/S call on stock trading at 23 dollar/S for premium of 4 dollar,
the breakeven price should be?

notes 上面說的是對於covered calls, breakeven price = initial price - call premium (23-4=19)
但为什么答案是premium +strike price=24

谢谢！

oh, 好像知道了。
这个题是call option 的吧！我觉得和covered calls 好难分辨。是不是如果出题，会强调是否investor owning the sock (underlying asset)

您看我能不能这样总结：
                       BreakEven Price
Call Option:       X+Premium
Put Option:         X-Premium
Covered Call:    So - Call Premium
Protected Put:    So + Put Premium

X: stirke price
So: trading price

谢谢！
