ViacomCBS, Discovery shares decline after recent records By Sinéad Carew Reuters (Reuters) - Shares in ViacomCBS and Discovery Inc tumbled on Wednesday, pausing a rally that has seen the stocks soar this year on increased appetite for value names, newly launched streaming services and an unwinding of bearish investor bets. ViacomCBS Class B shares last traded down 4.4% at $92.02 after hitting a record of $101.97 on March 15. Discovery shares last traded down 3.6% at $73.09 after hitting a high of $76.61 on Tuesday. ViacomCBS and Discovery have gained 146% and 142% year-to-date, respectively, as investors piled into undervalued names on expectations of a broader reopening of the U.S. economy while also eyeing direct-to-consumer streaming services that could help the more traditional media companies compete against newer rivals.
