Today's 3 Worst Stocks in the S&P 500

Although we don't believe in timing the market or panicking over daily movements, we do like to keep an eye on market changes -- just in case they're material to our investing thesis.

The stock market bounced back from a lackluster performance yesterday, seizing on strong U.S. manufacturing numbers to justify its gains. Only last month, Wall Street found itself stricken with anxiety from China's surprisingly weak manufacturing output -- how quickly things can change in a matter of weeks! The S&P 500 Index added 11 points, or 0.6%, to end at 1,839. All it needs is another 0.6% gain to reach all-time highs.

Cliffs Natural Resources , on the other hand, isn't in much danger of eclipsing record levels. Shares shed 2.4%, the most in the entire S&P 500, as Morgan Stanley added insult to injury by not only reiterating an underweight rating on the stock, but lowering its price target from $12 to $10 a share. For perspective, Cliffs Natural Resources would have to fall more than 50% to reach those levels. Even though the coal and iron ore miner swung to a profit in its most recent quarter, pessimism is easy to come by, and the company is currently fighting back against an activist investor intent upon changing the structure of the entire company. 

Even though the materials sector gained more than any other in the stock market today, Cabot Oil & Gas managed to join Cliffs at the bottom of the S&P Thursday, losing 2%. It's hard to understand the psychology behind a move like this, which came before Cabot's scheduled quarterly earnings release after hours today. Betting on whether earnings will overachieve or underachieve in any given quarter is like betting on black or red in roulette: unadvisable. Your best bet is to keep your money in your pocket -- Cabot Oil & Gas added more than 2% in after hours trading on Thursday after exceeding earnings and revenue expectations. 

The ADT Corporation continued its recent downtrend on Thursday, losing 1.9% in trading. Shares of the security company are off about 22% in the last month alone, losses mainly driven by ADT's weak quarterly report at the end of January. The business was only able to increase revenues by 3.7%, and earnings actually fell from the same quarter a year prior. The good news is that ADT pays a decent, sustainable 2.6% annual dividend, something you might expect from a profitable, low-growth company. However, ADT's balance sheets could use some work, as its debt-to-equity ratio sits around 1.4, and its current liabilities exceed its current assets.
