Entropic (ENTR +2.8%
) gains after receiving an upgrade to Buy
from D.A. Davidson. The firm believes Entropic's set-top box chips will be often used in digital-to-analog adapters to be deployed by Time Warner Cable (TWC
) as it migrates to an all-digital network. DA also believes TWC may be able to finish its all-digital migration ahead of its 5-year target.
