Collar

A collar can be established by holding a share, along with purchasing a protective put and writing a covered call, where both options at out-of-money..

For Example - ONGC

Underlying stock = Rs. 809

Buy Mar Rs. 800 Put @ Rs.16

Write Mar Rs. 880 Call @ Rs.7.25

Total price for this strategy = 809 + 16 + 7.25 = Rs. 832.25

Maximum Profit: Limited

Call strike - Initial spot price - Put Premium = 880 - 809 - 16 = Rs. 55

Maximum Loss: Limited

Initial spot price - Put strike + Call Premium = 809 - 800 + 7.25 = Rs. 16.25

So an arbitrage opportunity to the tune of Rs. 55 (max) is available if the price target of Rs. 880 or beyond is achieved. On the flip side, we have losses, which are capped at a maximum of Rs 16.25 for price Rs. 800 and below.
