Which stocks have the potential to be the next iRobot (NASDAQ:IRBT)?

First, let's explain what we're asking. Shares of home-robot-maker iRobot have surged over the last year, rising about 135%, thanks to terrific global demand for its latest Roomba 900-series vacuums and Braava floor-mopping models.

The question we put to some of our Foolish specialists is this: Which stocks have the potential to double (and then some) over the near term, like iRobot did? Below, they explain why they think Weibo (NASDAQ:WB), Epizyme (NASDAQ:EPZM), and a dark horse -- Ford Motor Company (NYSE:F) -- might fit the bill.

New leadership for an undervalued industrial icon

John Rosevear (Ford Motor Company): A century-old automaker is not the kind of company you'd expect to find on this kind of list. But humor me for a moment: Right now, Ford is arguably quite undervalued. It's trading at about 6.6 times its expected 2017 earnings, well below its historical multiple (in good times) of about 10 -- despite strong profits and a solid earnings-growth plan.

As I write this, Ford's stock price is right around $11. An iRobot-like rise would put it around $26. Is that plausible?

I think it's possible, because Ford is in a unique situation. Last fall, Ford rolled out a plan to transform itself into a company that not only makes vehicles, but also profits from a series of new technology-enabled mobility businesses.

It's a good plan that should boost Ford's profitability and keep it competitive as technology transforms the industry. But I think Wall Street hasn't priced the plan into Ford's shares for a couple of reasons:

• Ford told us how much this will all cost (a lot), but it didn't do a good job of explaining how and when those heavy investments in future technology will pay off.
• The pace of change at Ford so far has lagged the pace set by Ford's old crosstown rival, General Motors.

Both of those things fall on former CEO Mark Fields -- who was replaced on Monday by Jim Hackett. Hackett, who led a transformation as CEO of Steelcase and who is well regarded for both his team-building skills and his future-tech savvy, is expected to take Ford more aggressively into the future, while maximizing the profitability of its existing business.

If he's successful, it's entirely possible that Ford's annual net income could surge over $10 billion a year -- and its stock price could get into the mid-$20s. A bet on Ford now is a bet on Hackett and on the wisdom of the Ford directors who appointed him. It's not a slam dunk, but it could pay off big if everything works out.

A more promising microblogging platform

Keith Noonan (Weibo): Chinese social-media company Weibo has gained roughly 170% over the last year, but investors who missed out on those returns might still have the opportunity to capture explosive growth with the stock. Like Twitter, the company operates a microblogging platform built around 140-character messages. However, unlike its American counterpart, Weibo is already profitable and is posting huge growth in key areas.

The last fiscal year saw the company's sales increase 37%, with advertising revenue growing 42% year over year on new customer additions and increased advertiser spending. Net income generated by the social platform increased a whopping 211% compared to the prior year.

The platform's reach is growing at a rapid clip, as well. As of December 2016, Weibo boasted an extremely impressive 313 million monthly active users -- up 33% year over year -- while the company's average daily active user base increased 30% year over year, to reach 139 million. Thanks to backing from Chinese internet giants Sina and Alibaba, which both are substantial stakeholders in the social-media platform, Weibo is connected to two of the biggest players in the world's largest internet market and sees opportunities in promotions and feature integration that could continue to boost its sales and user base.

With a forward P/E value of roughly 47, Weibo trades at a premium relative to its expected earnings, and does face challenges that could disrupt its share price. However, the company appears to have plenty of room to continue growing its top and bottom lines and the potential to deliver huge wins for shareholders.
