Program Info

Global Sigma Plus (GSP) is the program GSG currently offers. GSP mainly trades US equity index futures and options. The program typically will sell options on S&P 500 futures and sometimes will also hedge them with US equity index futures. GSP is not a pure volatility-selling program. It is a directional prediction program combined with a volatility measure. The program will typically trade option within 6 weeks to expiration. The program may also buy back options before expiration in order to reduce risk or wait for better opportunities. GSP continuously monitors the risk/reward ratio on both potential and established positions.

There are three approaches GSP will use when market acts differently than expected.

1. The program may simply close out the positions and remain in cash. Most of the time, we find that simply admitting the models were incorrect and cutting losses quick is the optimal solution. This scenario typically happens when expirations are still quite away and the position hits a draw down limit specified by the program.

2. The program may hedge the position with index futures. This typically will happen when the program still believes the option will expire worthless or the program believes the options premium is too high and hedging is more profitable.

3. Third, it may roll over the position or hedge it with another option. This will depend on relative value of different options with different expiration or strikes prices.
