The hottest and coldest stocks in the market

There's an old saying among traders: "The trend is your friend."

And for a large group of stocks within the index, the trend has been either decidedly positive or negative. Those performance trends stayed mostly intact this month, as stocks exhibited a fair amount of volatility on the heels of an October that saw the best monthly gains in three years.

Some of the best performing stocks in the S&P 500 so far in November are the same ones that have been leading the way higher all year. As of Monday, more than half of the constituents of the index posted positive returns on a month-to-date basis, which might be expected given the S&P's relatively flat overall performance.
