Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Target (TGT) upgraded to Buy from Neutral at Citi with analyst Paul Lejuez saying he wants to catch the next 20% move up, which he believes will occur as the company continues to prove it is a "winner" in the current retail landscape. 2. Wayfair (W) upgraded to Buy from Hold at Stifel with analyst Scott Devitt saying the 12% decline in the stock price since the company's posted its Q2 results has created a compelling entry point. 3. Energizer (ENR) upgraded to Buy from Neutral at UBS with analyst Steven Strycula saying the stock has lost 45% of its market cap as a result of the initial integration challenges and higher leverage, but contends that at 9.5-times expected forward EBITDA, he sees the "bear case" being priced in. 4. Etsy (ETSY) upgraded to Buy from Hold at Stifel with analyst Scott Devitt saying the 20% decline in the stock price since the company's last earnings report has made its valuation more compelling. 5. Cerner (CERN) upgraded to Buy from Hold at Argus with analyst Jasper Hellweg saying the company is well positioned for growth having just completed its "self-described 'investment year'."
