Shares of Disney (DIS) - Get Walt Disney Company Report were ticking higher during afternoon trading on Tuesday, after Goldman Sachs became the latest firm to upgrade the stock.

Goldman upgraded Disney to a "buy" from "neutral," saying the 2018 box office may be the best in the company's history. Furthermore, it sees ESPN concerns subsiding, and Disney as a beneficiary of tax reform.

"I still like it, and people continue to recognize the value that is created here by the unbelievable catalog," co-founder of Najarian Family Office and Najarian Advisors Jon Najarian said on CNBC's "Halftime Report" Tuesday afternoon.

Najarian questions just how many blockbusters Disney will roll out implying that there is no shortage. "Whether he's right about ESPN slowing in its loss in subscribers. We'll see next quarter," he added.

"I like the stock, but don't you feel like we already knew the movie slate already? Every kid sitting in a comic book shop right now knows that these are films that are coming out," Ritholtz Wealth Management CEO Josh Brown said.

Brown stated that is was a "weird" rationale to go "uber-bullish" on the stock at this stage, because of the stock's already impressive run. Shares of Disney have climbed nearly 4% since the start of the year.
