The market's enthusiastic response to Comcast Corp's restructuring plans is driven by the prospect of a significant valuation re-rating for its media assets.

Following the company's announcement that it will spin off its NBCUniversal and Sky divisions from its broadband and mobile operations, shares have rallied sharply, with the stock jumping 23% in trading to reach a seven-week high of $27.10 on the Nasdaq.

The core investment thesis behind the surge is the potential for the newly independent media entity to trade at a premium multiple comparable to Disney.

Analysts note that Disney currently trades at approximately 10 times price-to-earnings, a multiple that could become accessible to NBCUniversal once it is unburdened by the slower-growth infrastructure business.

This separation allows investors to value the content and streaming assets on their own merits, rather than as part of a diversified conglomerate.

Comcast's decision to split the business addresses long-standing concerns about the conglomerate discount applied to its stock.
