A key aspect of this question is taking a look at valuation metrics in order to determine if the company has run ahead of itself.On this front, we can look at the Zacks Style Scores, as they provide investors with an additional way to sort 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. Investors should consider the style scores a valuable tool that can help you to pick the most appropriate Zacks Rank stocks based on their individual investment style.Athene Holding has a Value Score of B. The stock's Growth and Momentum Scores are C and D, respectively, giving the company a VGM Score of B.In terms of its value breakdown, the stock currently trades at 5.3X current fiscal year EPS estimates. On a trailing cash flow basis, the stock currently trades at 7.6X versus its peer group's average of 7.6X. 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, Athene Holding 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 Athene Holding fits the bill. Thus, it seems as though Athene Holding shares could have potential in the weeks and months to come.
