Top 10 Trucking Companies For 2014

May certainly ended on a confusing note for the broad-based S&P 500 (SNPINDEX: ^GSPC  ) , despite tacking on gains for the seventh consecutive month.

Like yesterday, which saw us rise on what I would have deemed somewhat poor economic news, the S&P 500 fell today on what appeared to be upbeat economic data. The Chicago PMI, which is a measure of manufacturing strength in the Midwest, surged to a reading of 58.7 in May, which is a strong reversal from the slight contraction it experienced in April. Furthermore, the final reading on the University of Michigan consumer sentiment index came in at 84.5, and signals that people are more confident in this recovery than they've been in years.

All that data went for naught, however, as the S&P 500 succumbed to the worries that it's come too far, too fast, and tumbled 23.67 points (-1.43%), to close at 1,630.74. In spite of today's downdraft, three companies bucked today's weakness and moved higher.

Diesel and natural gas engine maker Cummins (NYSE: CMI  ) turned in a strong gain of 1.7% despite no company-specific news. In this case, I'd postulate that today's move related to the bullish Chicago PMI data, which would suggest that manufacturing activity is picking up, and that the need for newer, more fuel-efficient engines to power trucking fleets will soon follow. Cummins was certainly sitting prettier when natural gas prices were in the $2/mbtu range, but even now looks like a fantastic value, with natural gas prices topping $4/mbtu, given the high prices of traditional gasoline, and the need for trucking companies to save over the long term by investing now in fuel-efficient engines.

The Company has commenced pre-clinical studies of an oral form of taliglucerase alfa. Its oral taliglucerase alfa is a plant cell expressed form of GCD that is naturally encapsulated within carrot cells genetically engineered to express the GCD enzyme. Pre-clinical studies of oral taliglucerase alfa demonstrate the stability of the enzyme in the cell and the capacity of the cell�� cellulose wall to protect the enzyme against degradation in the digestive tract in an in-vitro model of the stomach and intestines. Additionally, rats fed with lyophilized carrot cells expressing GCD have accumulated the active enzyme in the target organs; the spleen and liver. As of December 31, 2010, the Company had completed Phase III Clinical Trial.

PRX-102

The Company is developing PRX-102, its plant cell expressed modified version of the recombinant ! alpha-GAL-A protein, a therapeutic enzyme for the treatment of Fabry disease. Fabry disease is a rare, hereditary, genetic lysosomal storage disorder in humans caused by an X-lined deficiency of the alpha-GAL-A enzyme. The Company is in the animal evaluation testing phase of the development of PRX-102, which tests are based on a mouse model for Fabry disease.

As of December 31, 2010, its in-vitro experiments of PRX-105 have shown that the acetylcholinesterase enzyme in its ProCellEx protein expression system demonstrates biological activity on biochemical and cellular levels. In addition, early animal studies demonstrated that the acetylcholinesterase expressed in its ProCellEx protein expression system was able to treat animals exposed to the nerve gas agent analogues, both when injected with its acetylcholinesterase product candidate immediately before exposure or when injected after exposure. In March 2010, it initiated a preliminary phase I clinical trial of PRX-105, which the Company completed in June 2010.

pr-antiTNF

pr-antiTNF is a candidate for the treatment of certain autoimmune diseases such as rheumatoid arthritis, juvenile idiopathic arthritis, ankylosing, spondylitis, psoriatic arthritis and plaque psoriasis. The Company has designed the antiTNF as pr-antiTNF. pr-antiTNF is a plant cell-expressed recombinant fusion protein made from the soluble form of the human TNF receptor (TNFR), f! used to t! he Fc component of a human antibody domain. pr-antiTNF has an identical amino acid sequence to Enbrel and its in-vitro and preclinical animal studies have demonstrated that pr-antiTNF exhibits similar activity to Enbrel. Specifically, pr-antiTNF binds TNF thereby inhibiting it from binding to cellular surface TNF receptors and protects L929 cells from TNF-induced apoptosis in a dose-dependent manner.

The Company competes with Genzyme, Actelion, Crucell N.V., Biolex, Inc., Chlorogen, Inc., Greenovation Biotech GmbH, Symbiosys, Novartis AG/Sandoz Pharmaceuticals, BioGeneriX AG, Stada Arzneimittel AG, BioPartners GmbH and Teva.

Advisors' Opinion:

• [By Keith Speights]

  Other investors might wish that Pfizer would use some of its cash to acquire a few smaller companies. Protalix BioTherapeutics (NYSEMKT: PLX  ) has been mentioned as one possible candidate. The two companies already partner together on Gaucher disease drug Elelyso. In February, Protalix spurred rumors that Pfizer could be interested in buying the company after it announced that it had engaged Citigroup to pursue a "broad array of strategic alternatives."

• [By Maxx Chatsko]

  Industrial biotech isn't the only industry headed to Brazil. Protalix (NYSEMKT: PLX  ) entered into a technology transfer agreement with Brazil's Ministry of Health last week that will pay the company $280 million. The deal is big news for Protalix's first product, Elelyso/Uplyso, which was developed with partner Pfizer (NYSE: PFE  ) . The treatment is approved as an enzyme replacement therapy, or ERT, for adults with type 1 Gaucher disease, and it marks a huge step forward for the future of biomanufacturing. In the following video, Fool contributor Maxx Chatsko explains what this means for the product's commercialization and the adoption of Protalix's novel plant cell-based expression system for therapeutic proteins.

Advisors' Opinion:

• [By Bryan Murphy]

  When most investors hear the term "amusement park", one of two names comes to mind. The first one, of course, is DisneyWorld (or DisneyLand, depending on your locale), which of course is owned by The Walt Disney Company (NYSE:DIS), and probably set the bar for all other theme parks to come after it. Thrill-seekers of a slightly different age - ones without kids anyway - may recall fond memories of trips to Kings Island, Kings Dominion, or perhaps a visit to what some consider the best amusement park in the world, Cedar Point. They're all owned by Cedar Fair, L.P. (NYSE:FUN). And by most accounts, those leading theme park companies have provided equally compelling gains over the year for shareholders of DIS and FUN. But, there's a shift in what amusement park visitors are now seeking, and while Walt Disney Company or Cedar Fair aren't apt to be put out of business anytime soon, there's no denying that newcomer Independent Film Development Corporation (OTCMKTS:IFLM) - aka IndyFilmCorp - is better positioned to satisfy consumers' new definition of a thrilling theme park. Likewise, shares of IFLM may be poised to offer equally thrilling returns.

  That dynamic means that companies that can benefit from construction strength and cut costs will outperform others. For that reason, Murphy keeps Nucor (NUE) and�Steel Dynamics (STLD) at Buy. He wasn’t so kind to Reliance Steel (RS), US Steel (X) and AK Steel (AKS), which were all cut, though for different reasons.

  Reliance Steel & Aluminum (NYSE: RS  ) : up 100%
  The steel industry has been struggling lately, so it's especially remarkable to see Reliance Steel having made not one but two dividend increases in the past year. With increases from $0.15 per share last May to $0.25 in August and then to $0.30 in March, Reliance is bucking the negative trends in steel. What's especially noteworthy is that the company raised its payout even after announcing more than a $750 million deal to buy Metals USA in February -- a move that might have led other companies to rein in its payouts.
