JPMorgan on Wednesday started stock coverage of Altaba (AABA) , the holding company created after Yahoo's sale of its core internet business to Verizon Communications (VZ) - Get Report , with an "Overweight" rating and a $65 price target.

Altaba controls a significant interest in Yahoo! Japan and Alibaba (BABA) - Get Report , and JPMorgan analyst Doug Anmuth argues that both assets will present upside potential for the holding firm.

Anmuth expects that Altaba will close the discount gap it is currently trading at to Alibaba, and notes that a 10% increase in Alibaba's value translates into 7% increase in Altaba's net asset value.

Shares of Altaba were declining 1.2% on Wednesday morning. 

What's Hot On TheStreet

The stock market may be overvalued: Now may be the time to pay extra attention to red-hot tech stocks such as Apple (AAPL) - Get Report and Facebook (FB) - Get Report. As TheStreet first reported Tuesday afternoon, asset valuations are somewhat "rich" by standard metrics, Federal Reserve Chair Janet Yellen said in London during a conversation about economic issues with British Academy President Lord Nicholas Stern. Yellen's comments on equity valuation and bank strength closely mirrored Fed Vice Chairman Stanley Fischer's from an IMF event held earlier in the day.

The iPhone has changed how you make money: TheStreet's Scott Gamm is out with a piece that will really get you thinking. Apple's iPhone will turn 10 years old on Thursday. The device not only turned Apple into one of the world's most valuable companies, helping to boost its stock price more than 700%, it also changed the way we invest and trade stocks Gamm points out.

In fact, the original iPhone -- and the current versions -- have an internal stocks app, allowing users to check the broader market indexes and individual stock prices. Having this in your pocket was a big deal 10 years ago.

"I think it's actually made the life for a typical investor much easier," Angelo Zino, an analyst with CFRA Research, told TheStreet. "I think they've been able to tap news flows much quicker."
