Here is a chart that simply cannot be ignored.
Click on the chart and prepare to be dazzled with a tool that quite frankly I wish I had 20 years ago.
The site is www.markethistory.com and I have to tell you, it is quite amazing.
Imagine a place where you can type in any stock symbol you want and it will search for the highest correlation of stock prices over the last 65 days. It is quite incredible and such a time saver it is unreal.
The best part about all of this is that the correlation feature is but a fraction of the power the site holds. I won't go into details as it would take me quite a while, but I will tell you that they offer a one month trial subscription at no charge.
I encourage you to check it out as I am sure you will agree as I did as to how you ever got along without it.
