Shares of Twitter (TWTR - Get Report) finally gave investors something to cheer about Monday. The stock climbed nearly 7% to close at $17.09. 

The gains were fueled by MasterCard (MA - Get Report) , which is eyeing partnerships with Twitter and Facebook (FB - Get Report) . Facebook is an obvious partner, considering its billion-plus user base, but the payment-processing giant finds value in Twitter's unique payments services offering. 

"I think the way we would work with them is just the way we work with the other tech giants, we would figure out what we can do together, where our network could play into their space and connect up," Ann Cairns, president of international markets at MasterCard, said in an interview earlier in the day

For too long, investors have been bogged down with how poorly Twitter's user growth has been, especially compared to the golden child, Facebook. Although user growth hasn't wowed investors, revenue growth has actually been pretty impressive in the company's public years. 

Investors are hoping with CEO Jack Dorsey back at the helm, the company will find ways to boost sales and earnings - some of which could come from partnerships with companies like MasterCard - while at the same time growing users. 

Shares of Facebook closed at $112.55 Monday, down 3%. 


In a never-ending battle to fend off competition, Brocade (BRCD) announced the acquisition of Ruckus Wireless (RKUS) . The deal is for roughly $1.5 billion in cash and stock

The announcement had differing impacts on the stock prices, however. Shares of Ruckus soared 32.4% to $13.24 -- just shy of its 52-week high. Brocade closed at $9.19, down 13.6% on the day. 

Brocade has said the deal should close during its fiscal third quarter, and become accretive to the company in the first quarter of 2017. 

Some view the deal as a good, long-term move that will boost Brocade's offerings for 5G mobile services, once it is introduced. However, it could pit Brocade against some tough competition, namely Cisco Systems (CSCO - Get Report) . 

It's actually a large acquisition, considering that after the close of trading, Brocade only had a market cap of $3.7 billion. 


Apple's (AAPL - Get Report) recently launched iPhone SE starts at $399. That price point is still far too high for many customers in India. 

That's why Apple is seeking permission to import used iPhones into the nation. But it's not going to come easy. The company tried once before, last year, and was denied. While some of the public is pushing for Apple's wish to be granted, the government isn't so fast to say yes. 

First, Prime Minister Modi has encouraged local manufacturing within India with his program, Make in India. Allowing Apple to sell used phones could fly right in the face of that concept. 

Second, the competition isn't too keen on letting Apple into the market. During the holiday season, Apple saw iPhone sales soar more than 70% in India -- and that obviously doesn't include the SE unit and or used phones. So clearly, demand is there. 

If Apple does gain access to India in the form of importing used iPhones, it could be a boon for the company. U.S. sales have started to slow and the company is always on the look for its next big market. India is the second-largest country when it comes to mobile, so to say it's a big market is sort of an understatement. 

The problem with countries like China and India is the phone's cost -- 80% of the phones sold in India cost less than $150, meaning iPhones simply cost too much money for most of the population. This brings into question the company's margin potential. Used devices, at least for now, could help solve the price problem for both parties. 

Shares of Apple closed at $111.12, up 1% on Monday.
