10 Best Biotech Stocks To Buy Right Now

With the�SPDR S&P Biotech Index�up 32% over the trailing-12-month period, it's evident that investment dollars are willingly flowing into the biotech sector. Keeping that in mind, let's have a look at some of the rulings, studies, and companies that made waves in the sector last week.

Just as we've seen in previous weeks, it was relatively quiet in the beginning, but wow, did things pick up in a big way on Friday. In fact, Friday is the basis for this week's three most important biotech stories.

On the bright side, GlaxoSmithKline (NYSE: GSK  ) and Theravance (NASDAQ: THRX  ) received a much-expected drug approval for once-daily inhaled COPD maintenance treatment Breo Ellipta from the Food and Drug Administration. Having proved non-inferior to the placebo in trials, and delivering a favorable safety profile while reducing flare-ups and helping relieve air flow obstruction, Breo Ellipta has a good shot at being a blockbuster drug within the next couple of years. Breo Ellipta is expected to be available to patients next quarter. In addition, as I've alluded to on numerous occasions, it could be the impetus that encourages Glaxo to gobble up Theravance's Royalty Management -- one of two proposed entities that Theravance plans to split into. This is certainly a big win for both companies.

Advisors' Opinion:

• [By Melly Alazraki]

  Vertex Pharmaceuticals (VRTX)topped the list with a 38.4% return as of Wednesday's close of $48.48. This $9.8 billion market capnon-profitablecompany is all promise. It is itspipelinethat's drawing investors, especially thehepatitis C treatment telaprevirandpotential cystic fibrosis drug VX-770.
  
  Both diseases present large market opportunities: Liver disease caused by the hepatitis C virusaffects 3.2 million individualsin the U.S. and as many as 100 million people worldwide. Cystic fibrosis is an inherited genetic disease that affects about 30,000 people in the U.S. and has few treatment options.
  
  Analysts ! have favored the stock, with aconsensus buy recommendation. However, just on Thursday, Vertex announcedtwomore telaprevir studyresultsthat did not impress investors and the stock declined 2% to $47.50. Also, Vertex is not without competitors and is in a race with Merck (MRK) and its experime ntal Hep C drug boceprevir to be the first to reach the market.
  
  The stock's 52-week high of $52.13 was set on March 7, up from a low of $31.25 set on July 1, 2011.

  Vertex Pharma's (VRTX ) cystic fibrosis drug Kalydeco will be approved. More importantly, studies testing Kalydeco combined with other Vertex's cystic fibrosis drugs will show strong benefit in a larger swath of patients. Vertex becomes a cystic fibrosis company. Hepatitis C? What's that?
  
  Correct. Kalydeco was approved in January -- in my opinion, the most important drug approval in 2012. The Kalydeco-VX-809 combination study was successful, even though the Street is still debating the magnitude of the regimen's benefit to cystic fibrosis patients

Advisors' Opinion:

• [By Dug]

  Cubist Pharmaceuticals(CBST) is a major player in anti-infectives, which prevent and treat diseases, specifically those caused by drug-resistant pathogens. For example, Cubist's major product, Cubicin, is used to treat complicated skin and skin structure infections as well as bacterimia.

  The company has two anti-biotics that are in stage two of FDA approval. Since 2008, Cubist has grown sales and earnings per share 29% and 24% annually, on average. Its stock delivered annualized gains of 8.9% over that period. Recent deterioration of growth has led to a sell-off in Cubist, disconcerting investors.

  Its stock is down 4% over the past three months. Fourth-quarter adjusted earnings decreased 28% year-over-year, but did beat the consensus estimate by 38%. The top-line, down 3%, missed consensus by 1.1%. The operating margin strengthened during the quarter, from 28% to 29%, indicating pricing strength. Jefferies is optimistic about the outcome of a patent litigation lawsuit, which has a trial date in April, and considers the small-cap undervalued, at just 13-times forward earnings, a 39% peer discount. But, it considers reliance on Cubicin a concentrated risk.

  Bullish Scenario: Jefferies expects Varian to rise 39% to $31.

  Bearish Scenario: ThinkEquity foresees a drop of 10% to $20.

Advisors' Opinion:

• [By Melly Alazraki]

  Regeneron Pharmaceuticals (REGN)also had an impressive quarter, soaring 36.1% to $44.68 as of Wednesday's close, after setting an intra-day 52-week high of $45.11. This $3.88 billion market cap biopharmaceutical company has been on a tear with a yearly return of 67% as it continued to develop cancer, eye-condition and gout treatments.
  
  In fact, Regeneron, which sells onlyone product-- Arcalyst (rilonacept), for the treatment of a rare, inherited, inflammatory condition -- last monthsubmitted an applicationto the Food and Drug Administration for its VEGF Trap-Eye for the treatment of the eye disorder that is the leading cause of blindness in patients older than 65 in the U.S. and Europe. If the treatment is approved, Regeneron hopes to take market share from Roche/Novartis's (NVS) Lucentis.
  
  However, Regeneron'spipelinealsosuffered a setbackrecently. Aflibercept, its candidate drug for non-small-cell lung cancer -- a notoriously difficult-to-treat disease -- failed to increase overall survival time in a late-stage study. For now, analysts favor the stock with a consensus buy recommendation, but this setback follows others, making ongoing studies of aflibercept vital for Regeneron's future. The company co-developed aflibercept with Sanofi-Aventis (SNY).
