Investors interested in Medical - Biomedical and Genetics stocks are likely familiar with Vertex Pharmaceuticals (VRTX - Free Report) and Prothena (PRTA - Free Report) . But which of these two stocks presents investors with the better value opportunity right now? Let's take a closer look.

We have found that the best way to discover great value opportunities is to pair a strong Zacks Rank with a great grade in the Value category of our Style Scores system. The Zacks Rank is a proven strategy that targets companies with positive earnings estimate revision trends, while our Style Scores work to grade companies based on specific traits.

Currently, Vertex Pharmaceuticals has a Zacks Rank of #2 (Buy), while Prothena has a Zacks Rank of #3 (Hold). This system places an emphasis on companies that have seen positive earnings estimate revisions, so investors should feel comfortable knowing that VRTX is likely seeing its earnings outlook improve to a greater extent. But this is just one factor that value investors are interested in.

Value investors are also interested in a number of tried-and-true valuation metrics that help show when a company is undervalued at its current share price levels.

The Value category of the Style Scores system identifies undervalued companies by looking at a number of key metrics. These include the long-favored P/E ratio, P/S ratio, earnings yield, cash flow per share, and a variety of other fundamentals that help us determine a company's fair value.

VRTX currently has a forward P/E ratio of 14.52, while PRTA has a forward P/E of 48.40. We also note that VRTX has a PEG ratio of 1.48. This popular figure is similar to the widely-used P/E ratio, but the PEG ratio also considers a company's expected EPS growth rate. PRTA currently has a PEG ratio of 20.77.

Another notable valuation metric for VRTX is its P/B ratio of 5.07. The P/B ratio is used to compare a stock's market value with its book value, which is defined as total assets minus total liabilities. For comparison, PRTA has a P/B of 10.64.

These are just a few of the metrics contributing to VRTX's Value grade of B and PRTA's Value grade of D.
