Free Trading System for S&P 500 based on: US Gross Private Domestic Investment
Series ID: GPDIIndicator: US Gross Private Domestic InvestmentBeginning date: 1950-01-30Last Updated: 2017-02-10The GAIN realized using this trading system, investing an amount from a maximum long position of $ 100,000 to a short (negative) position of $ -100,000 , are the following:
|Trading period||Total gain||(Annual gain)|
|For all the years|| +312,956 $||( +4,669 $ ) |
|For the last 5 years|| +31,015 $||( +6,203 $ ) |
|For the last 10 years|| +25,907 $||( +2,591 $ ) |
|For the last 20 years|| +73,101 $||( +3,655 $ ) |
The trading position today is LONG
with a percentage of invested amount of: +84.71%
that in this simulation is +84,705 $ out of $ 100,000, with a
change in the invested amount from the day before of: 0%
Thus the trading signal is: BUY AND HOLD
A lot of economic indicators are published at 8:30 AM, before the normal trading hours, that starts at 9:30. To simulate the results of the trading system in the past years we suppose the worst case scenario considering information and generating trading signals only at the end of the trading time, at 15:00.
This automatic system can be improved in the next future, using indicator data in intraday trading, to maximize the gain.
In this simulation the gain is calculated using a constant bound of the invested amount, from a short position of $ -100,000 to a long position of $ 100,000. This restriction is designed in order to compare results obtained in different time intervals.
In fact, investors usually take the full amount available to them. So if after a few years their amount is doubled from $ 100,000 to $ 200,000, a gain of 1% will double from $ 1,000 to $ 2,000. In our trading system instead, an increase of 1% will always correspond to a gain of no more than $ 1,000 because it will be invested no more then $ 100,000. Soon it will be available also the more realistic simulation that uses the full amount available.
In the space below are visible two or tree monthly diagrams considering a trading period from 20 years ago untill now. The second and the third simulate the results basing the trading signals on the economic indicator GPDI and/or its derivative. The fisrt chart shows the main trading system that is a weighted sum of the other two.
For every graph there are represented:
On the left side of every diagram there is the axis of the S&P500 index value, while on the right there is the scale of the gain realized throught the trading system. The diagrams come daily dawned.
All data are showed reflecting the information when it was available, also postponed at 15:00, the closing time of the normal trading hours.
- the S&P500 index, with open, max, min and close values recorded in the market for each month (green and dark red bars);
- the long or short position to trade the index throught a positive (light green area) or negative (red area) amount;
- the course of the gain achived (blue line with light blue area);
- a line of reference with 6% annual yield (green line), useful to compare charts with different axis scale.
