Iron Condor
An iron condor is a four-leg options strategy consisting of a short OTM call spread and a short OTM put spread on the same underlying and expiry. It generates maximum profit when the underlying remains within a defined range and is widely used in NSE's weekly Nifty and Bank Nifty options.
The iron condor is constructed by simultaneously writing an OTM call, writing an OTM put, and purchasing a further OTM call and put for protection. The net credit received upfront is the maximum potential profit, achieved when the underlying expires between the two written strikes. The maximum loss is the width of the wider spread minus the net credit received.
On NSE, Bank Nifty weekly iron condors were among the most discussed multi-leg strategies, given the weekly expiry cycle and the typically high levels of implied volatility in Bank Nifty options. A participant might write a 500-point-wide iron condor on Bank Nifty, collecting ₹100–₹200 net credit, aiming for the index to remain within the range during the week. The defined risk (limited by the long options) made the strategy more manageable for retail participants compared to short straddles or strangles.
The wings of the iron condor — the long options purchased for protection — serve a dual purpose: they limit the maximum loss and also reduce the margin required by the exchange under SPAN methodology, since the position is treated as a spread rather than naked short options. This margin efficiency made iron condors more capital-efficient than equivalent naked short strangles.
IV crush benefits iron condors significantly. When IV falls after an event, the premiums of all four legs decline, and the short legs (which dominate the position) benefit more, accelerating profits. Conversely, a spike in IV hurts iron condors by inflating the short legs. This makes IV timing an important consideration when initiating iron condors relative to scheduled events.
A misconception is that the capped loss of an iron condor makes it a low-risk strategy. While the maximum loss is defined and limited, the loss-to-gain ratio is typically unfavourable — often 3:1 or higher. The strategy's statistical advantage historically came from the frequency of winning trades exceeding losing trades, but a sequence of large moves could result in cumulative losses that eroded or exceeded accumulated net credits from multiple successful trades.
