Ok I will (talk to the hand that is)
I did some backtesting of the "Chrystal Ball" ( only the afternoon call)
How I did it :
The website where the Chrystal Ball is released has historical CTI releases back to November 2005. In the release, there is:
- the signal (WEAK,FLAT,STRONG)
- the change from yesterdays close at the time of writing, in the DOW, NASDAQ and S&P 500
Since I dont have intraday data, I used the change from yesterdays close to approximate a buying/selling point (Do nothing if FLAT). Then exited the position at the close. (Before July 24, 2006 only the DOW was quoted)
*I know that this doesnt show the true profitability of the indicator because there are specifications on how to use it. Unfortunately, I can not test that without intraday data. However, this approach will give a basic indicator on the profitability and whether you should be listening.
I decided to only to test it on the NASDAQ and the DOW.
On the NASDAQ, starting Monday, July 24, 2006. There were 84 profitable calls and 81 unprofitable (50.9% success rate). The net return was 10.5% annually.
On the Dow, starting Thursday, December 08, 2005. There were 158 profitable calls and 112 unprofitable (58.5% success rate). The net return was 12.8% annually.
On the Dow, starting Monday, July 24, 2006 (to compare it to the NASDAQ). There were 96 profitable calls and 69 unprofitable (58.1% success rate). The net return was 13.4% annually.
As you can see the basic approach taken does as well as the market (plus alot of commisions).
Make your choice wisely.
Remeber that options change everything
