Citi analyst Suneet Kamath keeps a Neutral rating on Athene Holding in a research note titled "If ATH Can't Outperform in the Current Environment, Can it Ever?" The stock should be outperforming in the current environment given its "continued capital optionality," upside potential from the Voya Financial (VOYA) deal and a "benign" credit environment, Kamath tells investors in a research note. The analyst adds: "The fact that it is not raises the question: can it ever?" Kamath estimates Athene's tax rate advantage has gone from 20-21 points to 5-6 points. He also believes the company's offshore strategy might soon be replicated "by yet another company," creating more competition in the market and among investors. Kamath sees more attractive opportunities elsewhere in the Insurance space.
