Bernstein analyst Todd Juenger downgraded Time Warner (TWX) to Market Perform saying the U.S. television industry is entering a period of "prolonged structural decline." With viewers moving away from ad-supported platforms to non-ad-supported, media companies with the least exposure to U.S. advertising represent the most favorable investments, Juenger tells investors in a 48-page research note on the Media sector. He cut his price target for Time Warner to $90 from $101 and calls the downgrade a " very close call" with his new price target representing 15% upside from current levels. The analyst also downgraded shares of Disney (DIS) to Market Perform.
