Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. ViacomCBS (VIAC) double downgraded to Underweight from Overweight at Barclays with analyst Kannan Venkateshwar saying that even if he assumes "significant acceleration" in growth in the coming five years for ViacomCBS's streaming service and uses Netflix's (NFLX) multiple, there isn't much upside versus present stock levels. 2. Discovery (DISCA) downgraded to Underweight from Equal Weight at Barclays with analyst Kannan Venkateshwar saying he finds the optimism around some of these streaming launches like Discovery+ to be premature. 3. Peloton (PTON) downgraded to Sell from Neutral at UBS with analyst Eric Sheridan saying the stock is "emblematic of a market that values growth over any semblance of valuation that can be justified" on a multiple year view based on fundamentals. 4. Take-Two (TTWO) downgraded to Neutral from Buy at UBS with analyst Eric Sheridan saying that while he makes no changes to his operating estimates or multiples, he downgrades the stock to reflect a "more balanced risk/reward" after a 37% run-up in the stock price over the past six months. 5. Total (TOT) downgraded to Market Perform from Outperform at Cowen with analyst Jason Gabelman downgraded saying he sees a multi-year patch of in-line performance while the stock trades at an elevated premium to peers.
