Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Delta Air Lines (DAL) downgraded to Neutral from Buy at BofA/Merrill with analyst Andrew Didora saying his Flight Indicator data analysis suggests a "deceleration in domestic PRASM" in the first half of the year, coupled with other slowing demand indicators that include "weak ISM survey, declining CEO Confidence, airline pricing growth off highs, currency headwind, and government shutdown." 2. Illinois Tool Works (ITW) downgraded to Neutral from Buy at Citi with analyst Andrew Kaplowtiz saying the company's "overexposure" to "slowing" Europe is a risk. 3. Chevron (CVX) downgraded to Hold from Buy at HSBC with analyst Gordon Gray saying the scale of U.S. supply, and its responsiveness to any significant hike in price, will likely limit the price upside for crude. 4. Arconic (ARNC) downgraded to Neutral from Overweight at JPMorgan with analyst Michael Gambardella citing valuation. 5. XPO Logistics (XPO) downgraded to Sector Weight from Overweight at KeyBanc with analyst Todd Fowler citing his view that the big and bulky final mile market is increasingly competitive, along with ongoing uncertainty around European end markets.
