问题如下：
Based on Exhibit 1, the breakeven share price for Strategy 6 is closest to:
选项：
A.€22.50.
€28.50.
€33.50.
解释：
B is correct.
Strategy 6 is a bear spread, which is a combination of a long put option and a short put option on the same underlying, where the long put has a higher strike price than the short put. In the case of Strategy 6, the April €31.00 put option would be purchased and the April €25.00 put option would be sold. The long put premium is €3.00 and the short put premium is €0.50, for a net cost of €2.50. The breakeven share price is €28.50, calculated as XH – (pH – pL) = €31.00 – (€3.00 – €0.50) = €28.50.
怎么可以看出来一定是bear put spread? 为什么不可以是bear call spread? 我试了两个后，才发现了答案，但是这样计算有点慢。谢谢。
