Drybulk shippers have been slammed over the last few days courtesy of a plunge in capesize spot rates. However, according to the sharp eyes at Dahlman Rose, the volume of new spot fixtures has been exceedingly low of late. And taking a slightly longer perspective, spot rates are up more than 100% since last year.

A few things to keep in mind:

• Not all shippers are created equal: Dryships NASDAQ:DRYS) plays in almost strictly in the spot market and therefore it stands to reason that it should swing hard with spot rates. After closing the purchase of Quintana Marine, Excel Maritime (NYSE:EXM) now has a decent balance of long term and short term fixtures contracts. And then you have an outfit like Paragon Shipping (NASDAQ:PRGN) with most of its fleet leased out on long term - fixed price contracts.
  
  
• Despite the vast differences in the business models of these three companies, the market has not been very discerning in how it has treated its stocks, which suggests that there may be some arbitrage opportunity, should one wish to play it that way.
  
  
• Despite growing economic risks in China, it's tough to envision a collapse of infrastructure build-outs, or a sudden change in food needs in the BRIC countries and around the world in general. As long as these two activities hold up, it's tough to see a collpase in the shipping business;
  
  
• I can't stress enough that my long side interest in EXM and PRGN is heavily influenced by some sizable, and so far not so succesful, shorts in broad commodity ETF's.
  
  
• And lastly, the volatility in the shippers offers some very attractive options selling opportunities.

If you were paying close attention to this column last week, you would have sidestepped some of the pain and misery investors in many of the stocks discussed have suffered lately. Of late, we have seen the general direction of the markets turn positive, even in the face of news to the contrary.

Perhaps it is because investors have an appetite for stocks, since there seems to be few investment alternatives. Real estate is off limits and the yield on bonds and other fixed-income investments is pathetically low.

The theme for the week ahead is SMOOTH SAILING. In this week's column, we delve into some stocks that will be announcing earnings, and that may benefit from the changing tide of investor sentiment. To be sure, there will be several areas of choppiness as we continue to be bombarded by the stormy realities of a turbulent economy.

The chart for Campbell Soup (NYSE: CPB) looks M'm M'm good. Sporting a smooth line with nary a ripple over the past 12 months, management has done a great job at keeping both company earnings and share price up, even in the face of significant food inflation. While shares have been condensing during the past few months, recently they have been rising with a series of higher highs and higher lows. Be on the outlook for earnings of 44 cents per share on revenue expectations of $1.89 billion. Now that I think of it. That's a lot of soup wrapped in tin-plated steel -- one of many materials that has seen its price almost double in the past six months.
