Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Apple (AAPL) downgraded to Market Perform from Outperform at BMO Capital with analyst Tim Long saying that while the press has recently speculated about the order cuts for iPhone X, which he says reflects his first quarter model for a "weaker mix," he is "more concerned by a secular change" for the iPhone product. AK Steel (AKS) downgraded to Underperform from Buy at BofA/Merrill with analyst Timna Tanners saying AK Steel's "disappointing" first quarter and normalized earnings guidance is due to management's "commodity neutral approach," which limits benefits from higher steel prices. 3. U.S. Bancorp (USB) downgraded to Underweight from Neutral at JPMorgan with analyst Vivek Juneja saying the benefit from tax cuts and improving consumer spending are likely to be offset by increased tech spending. 4. Wayfair (W) downgraded to Accumulate from Buy at Gordon Haskett analyst Chuck Grom saying he believes it is important to remain disciplined with the stock at an all-time high, though Grom notes the rating change should not be interpreted as a concern for near-term sales trends, which he believes appear strong. 5. MetLife (MET) downgraded to Buy from Conviction Buy at Goldman Sachs with analyst Alex Scott citing ongoing uncertainty from an expanded reserve review following the announcement it will incur a $525M-$575M charge.
