A key aspect of this question is taking a look at valuation metrics in order to determine if the company is due for a pullback from this level.On this front, we can look at the Zacks Style Scores, as these give investors a variety of ways to comb through stocks (beyond looking at the Zacks Rank of a security). These styles are represented by grades running from A to F in the categories of Value, Growth, and Momentum, while there is a combined VGM Score as well. The idea behind the style scores is to help investors pick the most appropriate Zacks Rank stocks based on their individual investment style.Alexion has a Value Score of B. The stock's Growth and Momentum Scores are B and A, respectively, giving the company a VGM Score of A.In terms of its value breakdown, the stock currently trades at 13.4X current fiscal year EPS estimates. On a trailing cash flow basis, the stock currently trades at 8.2X versus its peer group's average of 20.7X. Additionally, the stock has a PEG ratio of 0.89. This isn't enough to put the company in the top echelon of all stocks we cover from a value perspective.Zacks RankWe also need to consider the stock's Zacks Rank, as this supersedes any trend on the style score front. Fortunately, Alexion currently has a Zacks Rank of #2 (Buy) thanks to rising earnings estimates.Since we recommend that investors select stocks carrying Zacks Rank of 1 (Strong Buy) or 2 (Buy) and Style Scores of A or B, it looks as if Alexion meets the list of requirements. Thus, it seems as though Alexion shares could still be poised for more gains ahead.How Does Alexion Stack Up to the Competition?Shares of Alexion have been moving higher, and the company still appears to be a decent choice, but what about the rest of the industry? Some of its industry peers are also impressive, including SINO PHARMACEUT (SBMFF), Moderna (MRNA), and Vertex Pharmaceuticals (VRTX), all of which currently have a Zacks Rank of at least #2 and a VGM Score of at least B, making them well-rounded choices.However, it is worth noting that the Zacks Industry Rank for this group is in the bottom half of the ranking, so it isn't all good news for Alexion. Still, the fundamentals for Alexion are promising, and it still has potential despite being at a 52-week high.
