Mixing Exposure • 253

When you bought the protection, the index was trading at 1,375, so
|
||||
you bought one-year puts about 5 percent OTM at $1,300. If the market
|
||||
had fallen heavily or even moderately during the first five months of the
|
||||
contract, your puts would have served you very well. However, now the
|
||||
puts are not 5 percent OTM anymore but 23 percent OTM, and it would
|
||||
take another Lehman shock for the market to make it down to your put
|
||||
strike.
|
||||
Keeping in mind that buying longer-tenor options gives you a better
|
||||
annualized cost than shorter-tenor options, you should be leery of entering
|
||||
into a hedging strategy such as the one pictured here:

Buying short-tenor puts helps in terms of providing nearer to
|
||||
ATM protection, but the cost is higher, and it gets irritating to keep
|
||||
buying expensive options and never benefiting from them (funny—
|
||||
no one ever says this about home insurance). Although there are no
|
||||
perfect solutions to this quandary, I believe the following approach
|
||||
has merit:
