Two types of Options: Call Option: Gives the holder right to buy an assets at
certain price within the specific period of time.

Protective (Buy a Stock & Buy a Put)
Advantages:
Potential gains or losses are created from the net effect of a long position in both the put and the stock. This establishes a floor, allowing unlimited profits while limiting the potential loss.
Should the stock price decline below the strike price before expiration of the option, the investor would exercise the put option & sell his or her stock at the strike price
Should the stock price increase above the strike price, the option would not be exercised & the investor could sell the stock at the higher price & recognize a profit if the stock price is above the overall cost of the position
* This is like purchasing insurance for your stock

Strangle (Buy Put & Call, Same Expiration Dates, Different Strike Prices; K2 > K1)
When is this appropriate?
The investor is betting that there will be a large price move, but is uncertain whether it will be an increase or decrease.
The stock price has to move farther in a strangle than in a straddle for the investor to make a profit
Disadvantage
The downside risk if the stock price ends up at a central value is less with a strangle
Advantage
The farther strike prices are apart, the less the downside risk and the farther the stock price has to move for a profit to be realized
