Deutsche Bank analyst Steve Powers downgraded Nu Skin Enterprises to Hold with an unchanged price target of $77. With the valuation at multi-year highs, the market is pricing in a "material acceleration" in sales and earnings trends, Powers tells investors in a research note. Further, the analyst thinks the strategic changes envisioned by new CEO Ritch Wood will be implemented more slowly than anticipated and that potential execution risks are not currently priced into the stock. He believes the Street's expectations for Nu Skin are currently too high.
