Our 1-day network model moved to a CASH position for trading on Friday. The ANO is still positive but not high enough for a long signal. All three swing trade models remain in CASH.

Forecast Models:    There are four neural network models and three swing trade models. The models are optimized to maximize the total return over the last two months. All models are experimental and are presented here for information purposes only. Their accuracy, which varies considerably over time, is usually greater than 72 percent based on a 90 day average. Additional details about the neural network model is provided here.

All four neural network models forecast the SP500 and differ only in their forward slope length in days. Three of the four are long-term models and the fourth is a 1-day model. The interpretation of the long-term forecasts needs some discussion. The three long-term models ANO values and ANO trend strength arrows are shown in the Summary above. These forecasts are a prediction of the direction of the forward slope and therefore there will be a delay in the expected change in index prices. The delay is about one-half of the forecast horizon days away. This means that if the 10-day model goes negative today, we would expect the market to turn down in about 5 days. Click here for details on long-term slopes.

There are three swing trade models. One for the SP500, one for the DJIA, and another for the NASDAQ 100. The results of the forecast analysis of these three are shown above. Currently, these models will only be either long or in cash. This will change in the future. The swing trade model is quite different from the neural network model used to make the four SP500 network forecasts. The swing trade model is based on a decision table paradigm whereas the network model is based on a neural network architecture. A genetic programming algorithm is used to create a neural network. An evolutionary programming algorithm is used to create a decision table. The network model is a numerical calculation while the decision table is more logical than numerical. The swing trade model trades less frequently than a network model and its signal may lag the market by a day or two. The network model will anticipate the daily change in the market direction. The network model will do better in a volatile market while the swing trade model will do better in a trending market.

Computing the Neural Network Forecasts:    We use an advanced neural network model and a genetic programming learning algorithm to create the neural networks used to forecast the direction of the SP500. The output of a neural network is a numerical value that ranges from minus one (-1.0) to plus one (+1.0), with -1.0 being a very strong indication of a negative slope over the forecast days and +1.0 being a very strong indication of a positive slope over the forecast days. For the 1-day model, the trading position we show in the Summary above is determined by computing an average network output value (ANO) from the individual networks and applying this average value to the setpoints which are also shown above. When this ANO rises above the long setpoint, a long position is given. When the ANO falls below the short setpoint, a short position is given. A cash position is indicated when the ANO lies between these two points. For the three long-term models, the ANO values are computed and shown in the Summary but position setpoints are not defined. A five percent trailing stop is given to reduce risk when either a long or short position is indicated.

The forecasts are updated after the session close and is usually posted here before 3:00 PM MT. Because of the timing of the update, trades may be made in the extended sessions or at open of the next trading day. Please read our disclaimer below.

Model Results: Trading results for the 1-day network model covering the last 165 trading days are shown in the two charts below. The vertical grid lines in these charts are 10 trading days apart.


The different color regions in the first chart correspond to the three possible trading positions. The second chart shows the trading positions as determined by the forecast model.



Performance Data:  Performance of the forecast model is shown in the table below. The results are given for three time periods. The first column of data shows results since the beginning of this year (Y-T-D). The second column of data shows results for the last 165 trading days, and the third column shows results for the last 45 trading days or about the last two months. The drawdown is the maximum drop in any position's value during the total days shown. The table below and the charts above may include results of previous model versions. All results shown are blind predictions. Page Top
