Quantitative Mechanics

How the Structure Works

Locks the investment within a defined profit/loss bracket for zero net premium.

A Collar is the ultimate institutional wealth preservation strategy. You own the stock, buy a Put for downside protection (floor), and sell a Call (ceiling) for the exact same premium. The trade costs ZERO rupees in net cash, completely eliminates catastrophic downside risk, and allows you to capture moderate upside.
