1. Financial Options & Option Strategy
CORP FINC Session 6 - Shanghai

2. Option contracts and markets
Call Option: the right to buy a financial asset in the future at a certain price and within a certain time
Put Option: the right to sell a financial asset in the future at a certain price and within a certain time

3. Buy and Sell Both Call and Put options can be bought and sold
The seller of the option is also called the writer of the option
For every buyer of an option there is a seller
The price at which the trader can trade is the strike price (exercise price)
Some options can only be exercised/traded at expiry date (European options) but nowadays almost all options can be traded daily (American options)
More and more selling and buying is done through on line transactions

10. In-At-Out of the Money

11. Option Value=Time Value + Intrinsic Value

12. What determines option value?
Stock Price (S)
Exercise Price (Strike Price) (X)
Volatility (σ)
Time to expiration (T)
Interest rates (Rf)
Dividend Payouts (D)

13. Before you know it….
You are setting up a strategy to make money or hedge risks
In this case you buy calls and puts of the same series ; this strategy is called a Straddle…
As you can see you can combine any combination of Calls and Puts , buying or selling, strike prices and different expiry dates and built your own strategy…

14. Arbitrage and put-call parity
Say you buy a put and sell a call of the same series at the same time
This is a synthetic short forward position
On such a position you should be able to make the risk less rate
Let’s take an example:

15. The put-call parity Assume: S= Selling Price P= Price of Put Option
C= Price of Call Option
X= strike price
R= risk less rate
T= Time then X*e^-rt= NPV of realizable risk less share price (P and C converge)
S+P-C= X*e^-rt
So P= C +(X*e^-rt - S) is the relationship between the price of the Put and the price of the Call

16. Speculations spreads and volatility
Buying a call will only profit you if the share price rises above the strike price plus the premium that you paid for the call
But you can set up a BULL SPREAD: buy a call at the money and sell one out of the money call with a premium close to the one that you are paying for the bought call
In the case of ebaY:
Buy Call $37.50 October 2005 (at $ 1.95) and sell Call $ 40 October 2005 ($ 1.15) If the price falls below $37.50 this speculator looses the net premium ($1.95-$1.15=$0.80)
A share price in between $ and $40 will generate a profit on the call and a loss on the sold call but the profit on the call will be higher since the strike price is lower
Above $40 this higher profit on the Call is kept above the loss on the sold call (for instance at $42.50 the call profit is $5 the loss on the sold call is $2.50 we got $1.15 for the sold option and paid $1.95 for the bought call so:
+$5-$2.50+$1.15-$1.95= $ 1.70
This profit will be the same for every share price above $40

17. Bull and Bear Strategies
Bull Spreads (speculate that the price will rise)
Using Calls (see ebaY example)
Using Puts
Bear Spreads (speculate that the price will fall)
Using Calls

18. Bearish Strategies Long Put
Naked Call (sell uncovered call; very risky!)
Bear Call Spread
Bear Put Spread
Put Back Spread

19. Set up a Bear spread with Calls or Puts
Buy a Call with strike price X and sell a Call with a strike price LOWER than X
Buy a Put with strike price Y and sell a Put with a strike price LOWER than Y
Proof in both cases that this is a Bearish approach (you bet on a lower share price)

20. Bear spread EbaY (buy call $ 37. 50 for $ 1
Bear spread EbaY (buy call $ for $ 1.65 and sell call $ 35 at $ 2.75)
Loose premium call - $ 1.65 and profit $ 2.75 from sold option; profit $ 1.10
Loose $ 2.50 sold call at $ profit $2.75 from sold call and loose - $ 1.65 net loss $ 1.40 beyond this point the call will gain equal to what sold call looses

21. Bear spread EbaY (buy put $ 37.50 for $ 2.70 and sell put $ 35 at $ 1.20)
At $ 35 profit from bought put $ 2.50 minus premium is -$0.20 (loss) and profit $ 1.20 from sold option; profit $ 1.00
At lower prices the gains from the bought put will off set the losses from the sold put.
Loose $ 2.70 bought put and profit $1.20 from sold put ; net $ 1.50 loss

22. Put Back Spread
Put back spreads are great strategies when you are expecting big downward moves in already volatile stocks. (Google?)
The trade itself involves selling a put at a higher strike and buying a greater number of puts at a lower strike price.

23. Example:
Using Intel (Nasdaq: INTC), we can create a put back spread using in-the-money options. With INTC Trading at $27.75 on July 12th 2005 , you might buy two of the October 2005, puts at $1.05 and sell one October put at $2.45
In this example, you would receive $35 for putting on the trade. If the stock jumped above 30, you would profit $35. However, the real money would be made if the stock made a big move to the downside.
The downside breakeven for this trade would be $25 At this price, the puts would be worth $2.50 while the 30 puts would be worth $5.
Below $25 the profit potential increases dramatically.
At $ 22.50: 2 bought puts will generate profit $1,000 and the sold put a loss of $ 750 and we will still have the $35 difference between the premiums: Total profit $ 285 !

BuyAMGN OCT 45 $2.55 ($255)
Cost of Trade$5,321
No matter how far the stock drops, as long as there is a protective put, the combined position will be worth $4,245.

31. Naked Put
Imagine that you want to buy International Business Machines (NYSE: IBM) but think it is due for a slight correction from its current price, $ By selling the $80 puts at $5.10, you collect $510 ($5.10 x 100 shares) per contract. If the stock drops to $75 and the puts are assigned to you, you will pay $80 for the stock. However, your net cost is really $74.90 per share ($80 strike - $5.10 premium)

32. Neutral Strategies
Reversals
Conversions
Collars
Straddles

33. Reversals
the reversal involves buying something in one market and simultaneously selling it in another to capitalize on whatever small discrepancy exists.
Traders do reversals when options are relatively underpriced.
In the absence of any price discrepancies, the following will be true:
Call price - put price =
stock price - strike price= $4
by selling a stock at $104, buying the call $100 for 7.50 (the offer) and selling the put $100 for 3.60 (the bid), the trader will lock in a .1 point profit.

34. Conversions The opposite of reversals
In the absence of any price discrepancies, the following will be true:
Call price - put price =
stock price - strike price=$4
Again:
Thus, by buying the stock for $104, selling the call $100 for 7.60 (the bid) and buying the put $100 for 3.50 (the offer), the trader will lock in an .1 point profit.

36. Straddles
Have you ever had the feeling that a stock was about to make a big move, but you weren't sure which way?
Let's imagine a stock is trading around $80 per share. To prepare for a big move in either direction, you would buy both the 80 calls and the 80 puts. If the stock drops to $50 by expiration, the puts will be worth $30 and the calls will be worth $0. If the stock gaps up to $110, the calls will be worth $30 and the puts will be worth $0.

Long strangles are comparable to long straddles in that they profit from market movement in either direction. From a cash outlay standpoint, strangles are less risky than straddles because they are usually initiated with less expensive, near-the-money rather than at-the-money options.
Long Strangle (the stock is at $ 65)
Buy1 60 $ $225
Buy1 70 $2.50 $250

38. Butterflies
The long butterfly spread is a three-leg strategy that is appropriate for a neutral forecast - when you expect the underlying stock price (or index level) to change very little over the life of the options. A butterfly can be implemented using either call or put options.
Long Butterfly - DJX = $75.28
Buy
1 DJX 72 $6.10 x 100

(wing)
Sell
2 DJX 75 $4.10 x 100

39. Butterflies (continued)

40. Put Ratio Spread
To create a put ratio spread, you would buy puts at a higher strike and sell a greater number of puts at a lower strike. Ideally, this trade will be initiated for a minimal debit or, if possible, a small credit.

41. The condor takes the body of the butterfly-two options at the middle strike-and splits it between two middle strikes rather than just one. In this sense, the condor is basically a butterfly stretched over four strike prices instead of three.
