Apple's (AAPL - Get Report) quarterly earnings report failed to inspire Wall Street traders last week, yet investors should remain energetic about the tech giant's stock, said Philip Martin, portfolio manager for Martin Investments at Covestor.

"Throughout their product lines, they have done a tremendous job of generating great profit margins and will continue to do so. With the ecosystem they are building, they are making a simple solution for the modern consumer," said Martin. "That's very powerful and going forward will continue."

Apple reported net income of $3.28 per share in its fiscal first quarter last Tuesday, surpassing Wall Street's consensus estimate of $3.24 per share. The iPhone maker posted revenue of $75.87 billion in the period, falling short of Street forecasts of $76.41 billion. Apple shares are down 8.5% so far in 2016.

Accenture (ACN - Get Report) is up over 15% in very choppy trading over the past 12 months. Martin expects a smoother ride higher in the coming year for the management consulting company.

"The world is becoming more technical, and the company's CEO said he sees tremendous upside in the digital consulting business," said Martin. "We are seeing all corporate areas becoming technical, so this will certainly benefit Accenture."

MasterCard (MA - Get Report) shares are down 11% so far in 2016 after rising 13% in 2015. Martin said it's a matter of profit-taking; the company's fundamentals remain strong.

"They make money on transaction processing, their network is built. And whether there is a fashion fad of Lululemon (LULU - Get Report) or Crocs, it does not matter because MasterCard is making money," said Martin.

Finally, he is a fan of Stryker (SYK - Get Report) , up 6.6% this year. Martin said the knee- and hip-replacement purveyor made a smart move in acquiring Sage Products for $2.8 billion last week.

"They added a good product line in terms of preventative treatment in hospitals as well as a potential tax write-off with that deal," said Martin.
