Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Parker-Hannifin (PH) downgraded to Market Perform from Outperform at Wells Fargo with analyst Andrew Casey saying future potential appears to be increasingly complicated by ongoing end market growth deceleration in the U.S. 2. Allstate (ALL) downgraded to Underperform from Neutral at Credit Suisse with analyst Michael Zaremski calling it the insurer most levered to homeowners' insurance at a time when record levels of precipitation in the U.S. raises the probability of worse than expected "non-catastrophe" claims volumes in the homeowners' line of business. 3. Alcoa (AA) downgraded to Hold from Buy at Deutsche Bank with analyst Chris Terry saying he previously thought Alcoa's legacy liabilities from pension and debt would reduce, the aluminum chain pricing will improve, and that its free cash flow would increase. However, he no longer sees this playing out in the near term. 4. Werner (WERN) downgraded to Underperform from Neutral at Credit Suisse with analyst Allison Landry saying that with a weakening demand backdrop, contract TL rates that are turning negative, and anecdotal evidence that suggests capacity remains relatively loose, she sees fairly meaningful risk to the second half of 2019 and 2020 EPS for the asset based truckers. 5. Hamilton Lane (HLNE) downgraded to Underperform from Market Perform at Keefe Bruyette with analyst Robert Lee citing valuation. This list is just a portion of The Fly's full analyst coverage.
