HCL Profits have almost doubled in the last 12 months ... Options premium will gain by more than 100% if HCL opens gap up above 610 like in the last 3 quarters.
Risk Potential: Options premiums could dip up-to 50% if stock falls. Exit if stock falls after results announcement (Probability is less and hence risk is also less)
