Nifty gamma exposure (NiGEX), which measures liquidity and volatility, fell slightly on April 28th with a closing value of 20L, after being at 23L on April 27th. Not much to infer from this drop. While this indicates a positive gamma environment, it's important to note that NiGEX should not be the sole factor in making investment decisions. Theta, the cost of owning gamma, benefits option owners in this scenario, as well as rewards delta, with call owners seeing a positive effect when asset prices rise. This also reduces directional risk and variance.
A decrease in NiGEX, despite Nifty closing with 0.8% gains on April 28th. VIX closed at 10.95. Additionally, NiGEX has exhibited volatile behavior over the past 200 days, with an average value of 291K and a median value of 1144K. The value range has been wide, ranging from a low of -116L to a high of 50L.
