Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Fortinet (FTNT) upgraded to Overweight from Equal Weight at Morgan Stanley with analyst Melissa Gorham saying she is more constructive on Fortinet heading into fiscal 2017 given the stable demand environment, free cash flow generation, easier comps, and more durable renewals. 2. Advance Auto Parts (AAP) upgraded to Strong Buy from Outperform at Raymond James and to Positive from Neutral at Susquehanna following the company's quarterly report. 3. Chevron (CVX) upgraded to Buy from Outperform at CLSA while the firm also upgraded EOG Resources (EOG) to Outperform from Underperform. 4. Harley-Davidson (HOG) upgraded to Sector Perform from Underperform at RBC Capital with analyst Joseph Spak saying that risks to the company's growth have dissipated, partly due to the potential of President-elect Trump's policies to spark increased consumer spending. 5. Cheesecake Factory (CAKE) upgraded to Buy from Hold at Argus with analyst John Staszak saying investors should be attracted to Cheesecake by its dividend hikes, share repurchases, and ability to open new stores while generating consistent comparable sales growth.
