In blue, you can see the returns of the previous version of the model. These returns were negative in 2011. It is more critical, because it means that the earlier version of the model was good for trend following, but not that good in a choppy market such as last year. Hence, the new version, in which we introduced a sell-in-strength rule, is showing good results in the two types of markets.
However, you are right: we will not have again the same sort of results as in 2008-2009.
However, I am pretty confident that the model is now robust enough to sustain any type of market.
There are two other aspects that are important (to my eyes) about this model:
1. At each stage, we can measure in real time the distance to the next signal and issue an e-mail alert (at least we are/will be testing these features.) This means "user's freedom". We (you) will be able to walk around with an iphone, get alerts on line in real-time and act if necessary. The heavy work is done by the model and the computers. We'd issue about two alerts per months/per model, which are easy to handle.
2. I was able to extract from the model the parameters that are sector dependent: Stop level, overbought and oversold levels, ATR level, porosity. These parameters are depending only on the volatility of a specific sector. This means that it should be possible to test the same model on different sectors without the need to redevelop the whole logic: only sector specific parameters would be adapted. This means that we will be able to easily run models on different ETFs.
In conclusion, what we will be offering here is
- number crunching capabilities that few hedge funds can get
- back tested/safe trading models
- the freedom NOT to have to stay close to the computer.
In a broad sense, this is our goal.
