Sixty-dollar-a-barrel oil. It's different this time.And investing as if this was just another temporary hike in the price of a barrel of oil isn't going to cut it over the next decade. In this column, I'm going to give you my take on how $60 oil has changed the game for investors. And 10 stock picks for winning this new game. It's not so obvious in the short run that the game has changed. In the short run, that $60 figure is just a price. But -- at least in the short run -- it's a price that moves the financial markets and the economy. When daily oil prices break below $60, stocks rally. And when crude moves strongly above $60 a barrel, stocks retreat. Check out the action on March 2 to see what I mean: A jump in the April crude-oil futures contract in New York to $63.36 that day helped the Dow Jones Industrial Average to a 28-point stumble. Investors and traders are familiar with this kind of pattern and the factors -- such as seasonal fluctuations in inventory and market reaction to news -- that produce these moves. In the short run, although the price swings may be more extreme, $60-a-barrel oil is business as usual. In the long run, though, $60 oil is shorthand for a set of changes in the global economy, ranging from "peak oil" to the rising cost of finding and producing oil.
