An option strategy:
-Buy one put option contract with 90 days or more until expiration
-Sell one put option contract (at the same strike price) with 45 days or less until expiration
-In 45 days, sell another 45-day put option contract at the same strike price
-Hold the long position until expiration if it appears that market will be profitable. Otherwise, sell it.

Profits can be realized since the price decay of the 45-day contract declines at a faster rate than the long option. The difference in premium decays allows investors to make money on the spread. The inherent risk in this strategy arises if prices rise in the short term and then increase thereafter.
