If you're a person who invests in stocks, there are two sources I highly recommend: Barron's and Investor's Business Daily. They each represent completely different philosophies, but, hey, that's what makes a market. They're both great at what they do, and sometimes I wonder if reading anything else really matters. [It does, but those two are great places to start.]
Barron's Online is free to everyone this week, so I might as well take advantage. I recommend you read Michael Kahn's column this week in Barron's Online, which examines some of the recent trading in energy from a technical perspective and it's possible meaning for the overall market.
Barron's: Are Weak Commodities Good for Stocks?
The quick take: We are enduring what appears to be a short term correction in commodities. The longer term bull market trend is still intact, but should be monitored. Since commodity stocks are currently the leading stocks in the market, this is doubly important.
