I came back from Home Depot, climbed the ladder, started cleaning the gutters (it’s 82 degrees now-for the Yankees), and sprained my back. So here I sit in a weird position glad I am not on I-4 stuck in traffic bound for the Daytona 500.
Anyway, there is a website which could assist you daytraders and/or short term traders. Here is the link.

Just type in your symbol and you can see which stocks and ETFs have a high positive or negative correlation. It probably means nothing to the daytrading gunslingers who like to trade the mo mo flavors of the day (or minute), but I like to trade with an edge and in a little more conservative manner. I like to watch one or two stocks that make up a good part of an ETF and then trade the ETF. For example if you type ABX one can see a 90% positive correlation with the ETF GDX. Type C and you can see an 85% positive correlation with XLF. Type INTC and there is an almost 80% positive correlation with SMH. By trading the appropriate ETF one can trade with a larger amount, with less risk, and not stroke out with every tick of a mo mo stock.
Hope this is of interest to somebody. Enjoy the Sunday afternoon. I am going to wait and see how Phil Mickelson blows this one.
