Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Walmart (WMT) upgraded to Conviction Buy from Neutral at Goldman Sachs with analyst Matthew Fassler saying selling consumables to middle-income consumers in small markets remains a compelling strategic position. 2. Hertz (HTZ) upgraded to Outperform from Neutral at Macquarie with analyst Hamzah Mazari saying he is more bullish on 2018 rental car pricing given fleet cutting by Enterprise, the positive impact on corporate travel from tax reform, and the potential US infrastructure bill creating excess demand. For Hertz specifically. 3. Alarm.com (ALRM) upgraded to Buy from Hold at Jefferies analyst John DiFucci saying Alarm.com is at the forefront of the trend towards connected homes and devices. 4. PPL Corp. (PPL) upgraded to Buy from Hold at Deutsche Bank with analyst Jonathan Arnold saying the current valuation is "too cheap to ignore," and U.K. energy regulator Ofgem failing to implement a mid-period review of RIIO-ED1 offers "decent prospects for a near-term re-rating catalyst." 5. Fluor (FLR) upgraded to Outperform from Neutral at Credit Suisse with analyst Jamie Cook saying investors will gravitate back to Engineering & Construction stocks as fundamentals for the group are improving.

Deutsche Bank analyst Chris Woronka lowered the firm's price target on Hertz (HTZ) to $6 from $10 and keeps a Hold rating on the shares. The Q1 car rental results are likely to confirm what all relevant data points have been pointing to since January: it will be a weak quarter across the board, the analyst tells investors in a research. However, the firm believes strongly that Q1 will prove to be the trough of the post-COVID correction cycle. It has a "clear preference" for owning Avis (CAR) over Hertz, saying the latter's recent CEO change introduces near-term risks associated with potential strategic pivots.
