Short-term options trades have become increasingly popular in recent months. These types of trades can be used for both speculation and hedging. For instance, a strategist apparently decided that the day of the FOMC meeting was a good time to buy a bearish put spread on iShares US Real Estate ETF (IYR). This two-week block trade could be a hedge or bet that mortgage rates are going up in the couple weeks after the June FOMC decision has been announced.
