Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Oneok (OKE) upgraded to Buy from Neutral at UBS with analyst Shneur Gershuni saying the merger with Oneok Partners (OKS) will create an attractive 6% yield growing at around 10%. 2. ASML (ASML) upgraded to Buy from Neutral at Citi with analyst Amit Harchandani saying the valuation, with the stock under-performing semi peers year-to-date, has "turned supportive again." 3. Restaurant Brands (QSR) upgraded to Outperform from Perform at Oppenheimer with analyst Brian Bittner saying the company's "accretive" cap-structure opportunities aren't appreciated while the recent Popeye's acquisition provides a tool to accelerate unit growth. 4. HCP (HCP) upgraded two notches, to Outperform from Underperform, at Raymond James. Analyst Jonathan Hughes is more constructive on HCP's attractive asset mix following an extensive transformation over the past year and said it now has the highest exposure among the Big Three Healthcare REITs to medical office buildings and life science assets and the lowest exposure to the more volatile senior housing operating sector. 5. Cheesecake Factory (CAKE) upgraded to Buy from Hold at Maxim with analyst Stephen Anderson arguing that shares as oversold after yesterday's nearly 10% pullback following the company's downward revision of its comp guidance for the current quarter.
