To be clear, there are traders that employ "scalping" as a standalone strategy in the market - those that attempt to make small profits on fluctuations in market prices. However, scalping gamma is different, and is anchored around delta adjustments to an existing options portfolio. Imagine a large volatility portfolio composed of both long and short premium positions. Long premium positions generally want the underlying to move quite a bit, while short premium positions generally want the underlying to sit still.
The gamma adjustment strategy works to help reduce these risks. For example, by scalping movement out of a long premium position, the gamma scalping can help provide income that covers theta expenses related to the position. Along those lines, gamma hedging related to short premium positions can help reduce directional exposure if the underlying security moves against you.
When purchasing options, the gamma of the overall position will be positive. Consequently, as the underlying stock rises, positive gamma positions get longer delta. As the underlying stock drops, positive gamma positions get shorter delta. As the underlying stock rises, short gamma positions get shorter delta. As the underlying stock drops, short gamma positions get longer delta.
The following points help summarize how a scalping overlay works, based on the gamma of the position, the direction of the underlying, and the associated adjustment. When you are looking to get short gamma, then you would consider making the following gamma adjustments to your portfolio:.
When you are looking to get long gamma, then you would consider making the following gamma adjustments to your portfolio:. In all cases the purpose of the adjustment is to get closer to delta neutral. As it relates to gamma scalping, we are mostly interested in two Greeks - delta and gamma. The next step is to visualize how the gamma of the option affects the delta as the underlying stock moves. Like delta, gamma is expressed as a numeric value between 0 and 1.
Now imagine that the gamma of that option is 0. But what is the new delta of that option? Gamma helps answer that question. Select personalised ads.

Gamma hedging is also employed at an option's expiration to immunize the effect of rapid changes in the underlying asset's price that can occur as the time to expiry nears. Gamma hedging is often used in conjunction with delta hedging.

For example, if a trader buys call option, he will go short on stock to hedge his position. But when it comes to large portfolios which follow a delta neutral approach, occasional adjustments will be required to keep it delta neutral.
A very systematic approach to these adjustments is "gamma scalping" or "gamma hedging. There are traders who use "scalping" as a standalone strategy just to make small profits with price fluctuations. However, scalping gamma is different. It is hooked around delta adjustments in an option portfolio.
Imagine a large portfolio that consists of both long and short premium positions. Long premium positions will want the underlying to move a bit, while short premium positions will want the underlying to be stable. In other words, the risk involved with the long premium position is lack of movement, while the risk involved with the short premium position is significant movement in the wrong direction. These risk can be reduced with the help of gamma adjustment strategy.
A long premium position is the basis of true gamma scalping. Due to the positive relationship between underlying price and delta, your position delta will decrease when the underlying moves against you and increase when the underlying moves for you. The objective here is to neutralize the cost of theta on the long premium position.
Elections, earnings, economic data etc are all good reasons to think that market can give a potential move and the exact time to initiate a true gamma scalp strategy. We start by buying a straddle call and put option of same strike price , expecting market to either go up or go down. So to start off, I have a delta neutral position. When the market goes down, according to gamma scalping, my delta is now approaching a higher negative value because of the put. The negative delta of Put is going to overshadow the delta of long call.
To restore to a delta neutral position, I will add stocks to add delta and thus making delta neutral again. Similarly when the underlying rises, the call delta increases and the entire delta of my position heads to become a positive value. Thus, to restore my delta neutrality, I will now sell the stocks to get a negative delta.
It will again help me re-establish a delta neutral position. The reason behind this continuous adding and selling of stock to maintain delta neutral position is theta. We are long on straddle and theta is acting against us every single day. Imagine a trader has bought lots of Nifty CE when Nifty is trading at The premium for this call is Rs Delta of this option should be close to 0. The delta of the position is 0. In order to be delta neutral, he will sell 25 lots of Nifty.
If Nifty rises to , the delta of this call option will range approximately at 0. He has already sold 25 lots, so now he has to sell the remaining 15 lots at the price of Selling these 15 lots is gamma scalping in action.
