Does it mean "buy the stocks of the banks"?
Goldman analysts said one good way to play banks may be in the options market because many investors are “overlooking the potential for a rate hike to be a positive catalyst for these stocks.” They recommend buying both 6-month and 12-month calls on financials. Buying calls is a way to gain exposure to a stock without owning it out right and it gives the investor the right to buy a security at a set price and time.
