To minimize your risk, select a key with low return variance. Each key is also assigned a rating code , describing the properties of the associated strategy. This should greatly help you in your selection. In addition to our listing, we propose customized keys. A mixed key combines two or more stocks, incorporating correlations and time lag between the stocks.
Mixed keys are more difficult to design and thus more expensive, but they are also more powerful.
A universal key is a key that works well with all stocks, usually providing a lower return but a greater robustness. Non universal keys are sometimes referred to as targeted trading keys , since they are attached to specific stocks. Our fees are small, compared with your broker's trading fees. Note that our recently updated return rates take into account the transaction cost . We also provide a spreadsheet to help you assess the impact of trading fees.
