As U.S. markets continue to flirt with all-time highs, it can seem daunting to find stocks positioned for huge growth and returns over the next decade. Because it's difficult to uncover these well-positioned stocks, three Motley Fool contributors have ideas that you should dig into: (NASDAQ:JD), Aptiv (NYSE: APTV), and Tesla (NASDAQ:TSLA). Here's why.

An e-commerce powerhouse

Jeremy Bowman ( One of the biggest growth opportunities in the world today is in Chinese e-commerce. Despite a slowing growth rate, China's GDP is still expanding more than twice as fast as that of the U.S., and is set to displace this country as the world's biggest economy in the next 10 to 20 years. 

Meanwhile, online retail is even more popular in China than it is here because the country is already the world's biggest e-commerce market, and is a major reason why.

JD is China's biggest online retailer by revenue since it operates both as a direct seller and as a marketplace, much like The company has also built a network of more than 550 warehouses across China and operates its own delivery and logistics service, allowing it to deliver 90% of customer orders in one day or less.

Recently, the company opened up its delivery network to individual customers, which can now send parcels themselves through JD, opening up another revenue stream. And it is aggressively investing in technology like drone delivery and automation to strengthen its leadership in e-commerce, logistics, and delivery, and expand its reach in rural China.

In its most recent quarter, revenue rose 20.9% to $18 billion, while sales at its services segment, which includes its marketplace and third-party logistics and delivery services, rose 44% to $1.9 billion, showing that the company is growing its core business at a strong rate and transitioning to higher-margin services, which helped double its adjusted operating profit margin last quarter to 1.6%. 

With the secular growth in China's online retail market ahead of it, JD's strong position as the leading direct seller in China, and its fast-growing service businesses, the company looks poised for huge growth over the next several years. At a price-to-sales ratio of less than 1, the stock is much cheaper than most online retailers, making it an appealing buy today. 

A driverless juggernaut

Daniel Miller (Aptiv): If you're looking for a stock with upside over the next decade, look no further than Aptiv, a provider of software, electronics, and technology dedicated to developing the next generation of driverless vehicles and smart cities. Despite its long-term potential to thrive as the race toward driverless cars intensifies, weak 2019 guidance and slowing light-vehicle sales have pushed the company's consensus forward P/E to a modest 16 times.

Aptiv may not be a household name to many investors, but its technologies continue to gain accolades. One example: in June, Aptiv, in collaboration with Audi, won the 2019 CLEPA Innovation Award (from an association of European auto parts suppliers) for its Automated Driving Satellite Compute Platform.

In April, Aptiv was presented by Automotive News with a 2019 PACE Award (recognizing suppliers for game-changing innovations) for that same platform. Oh, and that was the 21st time Aptiv has been recognized with a PACE award.

Beyond its technologies, the company is continuing to expand its overall strategy with its recent opening of the China Autonomous Mobility Center. China has a high market acceptance of driverless vehicles, and with the government's strong push for electric vehicles, the world's largest automotive market will be a perfect place to develop and test driverless technology.

While a mainstream driverless future remains in the distance, Aptiv and its partnership with Lyft have already logged well over 30,000 paid automated rides, with a 4.95-star rating out of 5 -- proving people will pay for the service. If you're looking for a stock poised for huge growth, finding one like Aptiv that's positioned to thrive on an upcoming megatrend is a great place to start.

Optionality galore

Brian Feroldi (Tesla): Tesla is one of the most divisive companies that I've ever seen. Bulls believe that it's only a matter of time before its products completely take over both the auto and energy markets. Bears believe that this company is always on the verge of bankruptcy.

While I see plenty of reasons to be both bullish and bearish, I think that the auto and energy markets will go through truly disruptive change in the 2020s. The economics of switching to electric vehicles and solar have become very compelling, which bodes well for Tesla's continued growth.

Its near- and long-term product road map also offers investors plenty of reasons for optimism. The Model 3 rollout is still ramping up and should remain strong as it spreads to a more international market. The same goes for Powerwall, Powerpack, and its solar roof, all of which have been put on the back burner because of challenges with its Model 3 ramp up.

Meanwhile, it also has plans for a semi truck, next-generation roadster, pickup truck, Model Y, and bus within the next few years. While success is never guaranteed, the company's products have historically sold well right out of the gate since it is so good at generating buzz ahead of their launch.

Finally, Elon Musk has stated that its fleet of 1 million autonomous ridesharing vehicles will come online next year. Tesla's history shows that the timeline is probably overly ambitious, but if the company can be first to market with a fleet of autonomous vehicles, then it could generate a huge amount of shareholder wealth.

This stock isn't for the faint of heart, but the 2020s are poised to be an amazing decade for the business. If everything goes according to plan, then Tesla's stock could earn investors multibagger returns from here. That's why I've committed a small amount of my capital to it and plan on holding it no matter what headlines come out next.
