There is a way to get decent returns. Not 200% over 1 year, but good enough.
Here's an easy trick: Lets say you decide to buy funds. You can then calculate the percentage change in value over a particular time frame:
Shown here are 27 funds with their percentage chages over the past 1 month.
You now form a strategy of buying into the fund with the highest growth rate. This data is reviewed and change of funds performed after a certain time interval, eg. every 1 month.
Lets see how this holds up. We can download historical data for all the 27 funds going back 2 years:
Next we normalize each according to their average value:
We now use this strategy on the data. We use an algorithm to evaluate the percentage change in value and act accordingly:
We are now tracking the top performing fund at each particular time in the data series.
