One 'canary in the coalmine' for this market is oil. How can the economy be improving if the lifeblood of the how we measure it, oil, is dropping like a stone? This is one to watch.
The second chart is of Gold, more particularly - the ETF, GLD. This isn't a great sign to see gold dropping like a stone when the market is in turbulence. It means, instead of looking for other places to put any monies taken out of stocks, investors are instead simply taking money off the table. This is another one to keep an eye on.
