解释:
I understand you should buy call option to increase convexity. But by buying call options on long-maturity govt bond, which is the call option to 30 year bond, probably can't give you higher return. It's because the expected 30 year bond yield will be stable in 1 year, therefore the 30 year bond call option price will not increase. Am I right?
