Basic Option Strategies: Short Call Option Strategy (Part 2)

Add to Flipboard Magazine.  


In , we explained about Long Call. In the second part of this article, we take a look at another basic option strategy which is called Short Call.

About Short Call Strategy

Short call means to sell one (or more) call option. Selling option is also known as writing an option. Short call is used when an option trader expects the price of the underlying asset to drop significantly below the strike price before the option expiration date (American-style) or at the expiration date (European-style).

The chart below shows that if the underlying asset is below the strike price at expiration date, the seller’s profit will be the premium earned from selling the the option contract. However, if the market rises then the seller will have unlimited loss.

Short call is considered a risky option strategy. Because of this, it is only suitable for experienced option traders that strongly believe the price of the underlying asset will fall or remain flat.

The calculation formula for short call strategy is as follows:

[(Market Price at Expiration – Strike Price) x (Contract Size)] + Premium Received

This chart and table illustrates the profit and loss assumptions for different market prices at the expiration date.

Short Call Option Strategy

Option Product FBM KLCI Index Option (OKLI)
Underlying Asset FBM KLCI futures (FKLI)
Current Market Price E.g. ≤ RM 1,600
Strategy Sell 1 Lot of OKLI at RM 1,600 (The Strike Price)
Call Option at RM20 (The Premium)
Premium = Premium Received x Contract Size
= RM20 x 50
= RM 1,000
Breakeven Point RM 1,620

1660 = [(RM 1,660 – RM 1,600) x 50] + RM 1,000
= RM 3,000 + RM 1,000
= RM 2,000 (Nett Loss)
1620 = [(RM 1,620 – RM 1,600) x 50] – RM 1,000
= RM 1,000 – RM 1,000
= RM 0 (No Gain or Loss)
> 1620 * If Market Price at Expiration is above RM 1,620, the seller’s losses will be unlimited.
