Exxon Mobil (XOM) upgraded to Neutral from Underperform at Credit Suisse with analyst Edward Westlake saying that after underperformance versus the S&P, the stock has option value. The analyst also raised his price target on the shares to $83 from $78. 2. RBS (RBS) upgraded to Buy from Hold at Berenberg. 3. Windstream (WIN) upgraded to Hold from Underperform at Jefferies with analyst Scott Goldman saying he sees less risk to estimates following management's 2017 guidance. The analyst upped his price target for the shares to $7.50 from $6. 4. Sarepta (SRPT) upgraded to Outperform from Market Perform at Leerink with analyst Joseph Schwartz saying the stock now reflects "reasonable expectations" for the Exondys launch. Management's new revenue guidance looks "highly conservative," Schwartz tells investors in a research note. The analyst believes share upside could come from Exondys 51 approval in Europe and/or successful development of follow-on antisense candidates. He raised his price target for Sarepta shares to $47 from $27. 5. Estee Lauder (EL) upgraded to Overweight from Neutral at Piper Jaffray with analyst Stephanie Wissink saying the growth is de-risked following the guidance reset. The analyst is "bullish" on the prospects for double digit earnings growth for investors that can look into FY18. She raised her price target for the shares to $95 from $81.
