Market Canary In the Coal Mine Throws Up Red Flag

Another market canary in the coal mine has throw up a red flag today. That said, the Dow is once again trading at fresh record highs, just as is the S&P 500. This market looks more like a bubble with every day that passes. I suggest keeping tight stops!
Here is the headline today on Marketwatch:

"A stock-market index of small caps is at its weakest versus the S&P 500 since the financial crisis, suggesting the market has a liquidity problem."
