Buying Call options

3-month European call with a strike price of $20 that is priced at $1.00

Currently, the price of the underlying stock is $25.50

= $25.50-($20+$1.00)

= $4.5

For each set of trades you will make, please describe the trades you do and how much money you will make.

3-month European call with a strike price of $20 that is priced at $1.00

Currently, the price of the underlying stock is $25.50

= Stock Price - Strike Price

= $25.50-($20+$1.00)

= $4.5

3-month European put with a strike price of $20 that is priced at $4.00

Currently, the price of the underlying stock is $25.50

= Strike Price - Stock price

= $20- $25.50

= 0

The PUT option is worthless

3-month call with a strike price of $25 that is priced at $8.50

Currently, the price of the underlying stock is $25.50

= Stock - (Strike Price + Premium )

= $25.50 - ($25+ $8.50)

= -$8.0

3-month put with a strike price of $25 that is priced at $7.00

Currently, the price of the underlying stock is $25.50

= Strike - Stock

= $25 - $25.50

= 0

(Option is worthless)

If we factor in interest rate let's say 4% for the profit-making options

3-month European call with a strike price of $20 that is priced at $1.00

Currently, the price of the underlying stock is $25.50

= Stock Price - Strike Price /(1+4%*3/12)

= $25.50-($20+$1.00)

= $25.50- ($19.80+$1.00)

= $4.70

By factoring in the interest rate and the present value of the strike price, we will make more profit.

Previous profit i.e.$4.50 < $4.70.

1) Arbitrage Trades is $4.5.
