Finding the top US stocks is challenging, especially since Wall Street analysts are getting nervous about a vulnerable market ahead. The Dow Jones index has been falling for the 5th straight session. Moreover, the heightened threat of the Delta variant, with school re-opening in the current month, might give a huge knock to the market.

In these unpredictable times, I think it’s always wise for investors like me to focus on the long term. After all, the top US stocks which have the potential to grow in the long run can guard my portfolio against the spasms of volatility.

With that in mind, let’s take a look at two of the top US stocks I plan on buying and holding for the next decade.

The rising cash-free world

Square (NYSE:SQ) is a digital payment company. The highly popular Square Cash App, which provides peer-to-peer payment solutions, has expanded its services to include digital banking and investment services. Cash App generated a gross profit of $546 m in the second quarter of 2021, representing a 94% increase year on year. This is one of the reasons why the firm is on my top US stock list.

The recent, first-of-its-kind partnership between Square and SoFi Stadium, a world-class facility and the largest stadium in the NFL, is expected to take the business of the digital payment company to new levels. In addition to this, the firm has also acquired Afterpay, an Australian buy now, pay later company. Personally I think this acquisition is quite complimentary and allows the group to continue competing with rivals like PayPal. 

In light of this progress, I’m very confident about Square’s long-term growth potential. But it’s far from risk-free. I am somewhat concerned regarding Square’s negligence towards the ever-increasing competition within the digital payment world. With competitors offering lower fees, improved customer support and alternative platforms, the company might start losing customers if action is not taken soon.

The Upsurge in Consumer Robotics

iRobot (NASDAQ:IRBT) is a consumer robot company with more than 30 years of experience in the industry. Sales of its award-winning Roomba vacuuming robot and the Braava family of mopping robots are consistently rising. It led to an increase of 31% in revenue in the second quarter of 2021. In addition, the increase in sales of mid-tier and premium robots contributed to 82% of sales. Needless to say, that’s quite encouraging, and hence why it’s on my top US stocks list.

The company strives to differentiate by improving the iRobot experience through the ongoing innovation of its existing product offerings. Quite recently, the robotics company enhanced the iRobot Genius Home Intelligence Platform. This is a powerful AI-based solution that comes with a wide range of user personalisation services.

iRobot is a global enterprise that has sold more than 30 million robots worldwide. But like other technological products, it’s at risk of encountering patent infringement cases like the one with SharkNinja. Moreover, Internet of Things (IoT) devices are continually exposed to potential cyberattacks for as long as they are connected. Hence active monitoring is a must for the company.

Its H1 handheld vacuum is another popular home cleaning solution that was recently added to its product portfolio. With the company continuously improving customer experience with innovative products and improved service, I believe iRobot is en route to join the ranks of the tech giants.

Final thoughts on these top US stocks

Both these businesses have a prosperous future in my mind. While they undoubtedly have challenges to overcome over the long term, I believe their share prices can continue to climb even higher. Therefore I intend to buy these top US stocks for my portfolio.
