Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Teva (TEVA) upgraded to Buy from Neutral at BofA/Merrill with analyst Sumant Kulkarni said the last night's unfavorable Court ruling is not a surprise and the company has already lowered its financial outlook on higher generic price erosion. Now that the ruling is out of the way, the analyst views Teva risk/reward as favorable and notes shares are down 58% since July 16, 2016 when it provided a more optimistic outlook. Over time, Kulkarni expects investors will be rewarded from Teva's leading generic pipeline and underappreciated brand pipeline. 2. CBOE Holdings (CBOE) upgraded to Buy from Underperform at BofA/Merrill with analyst Michael Carrier upgrading CBOE Holdings two notches to Buy from Underperform and raising its price target to $85 from $74. The analyst sees multiple sources of upside to accelerate earnings driven by the BATS deal, increased capital deployment, rising volatility off of historic lows, and potential US tax reform. 3. Monro Muffler (MNRO) upgraded to Buy from Hold at Gabelli with analyst Carolina Jolly citing valuation, acquisition growth, and a history of execution. 4. Tupperware Brands (TUP) upgraded to Neutral from Sell at B. Riley with analyst Linda Bolton Weiser increasing her price target for the shares to $54 from $47. 5. ViaSat (VSAT) upgraded to Outperform from Market Perform at Wells Fargo with analyst Andrew Spinola saying the valuation is attractive for "strong" medium- and long-term growth from the Viasat-2 and Viasat-3 launches. The analyst expects EBITDA growth of 41% and 21% in fiscal 2019 and fiscal 2020, respectively. He raised his price target for the shares to $94-$98 from $76-$78.

Cboe Global Markets announced plans to refocus its digital asset business to leverage its core strengths in derivatives, technology and product innovation while realizing operating efficiencies for both Cboe and its clients. These changes are being made as part of Cboe's strategic review, taking into consideration the lack of regulatory clarity in the digital space. Cboe plans to transition and fully integrate its digital asset derivatives, currently offered by Cboe Digital, into its existing Global Derivatives and Clearing businesses. Additionally, the company plans to wind down operations of the Cboe Digital Spot Market, the company's spot digital asset trading platform, in Q3, subject to regulatory review. Cboe plans to transition its cash-settled bitcoin and ether futures contracts, currently available for trading on the Cboe Digital Exchange to the Cboe Futures Exchange in the first half of 2025, pending regulatory review and certain corporate approvals. This move will consolidate all Cboe U.S. futures products, including digital asset futures, onto one exchange. In addition, Cboe will maintain ownership and operation of Cboe Clear Digital, the clearing arm of Cboe Digital, and plans to align Cboe Clear Digital with Cboe Clear Europe, its European clearing house, under unified leadership. Vikesh Patel, the current President of Cboe Clear Europe, will now also oversee U.S. clearing. The company anticipates that the wind down of the Cboe Digital Spot Market operations will have an immaterial impact on Cboe's net revenue in 2024. The company estimates that expense savings will be in the range of $2M-$4M in 2024, with savings expected to be in the $11M-$15M range on a normalized annual basis.
