3 Potential Tenbagger Stocks You Shouldn’t Miss

Despite the title, let’s be clear: Not everything in your portfolio can (or will) deliver awesome returns overnight. In general, a more balanced approach works in the long term. 

However, potential “tenbaggers” — stocks that appreciate 10 times their initial purchase price — are out there. WallStreetZen’s Potential Tenbagger screener can help you find them. 

Below, we’ve done some preliminary research on three such stocks.

These aren’t random selections. We cross-referenced the picks with our Zen Ratings system, which uses 115 factors to identify which stocks display the most promising signs of future growth. The stocks are then graded from A through F, just like school grades. A-rated stocks produced an average annual return of +32.52% since 2003.

Here are three stocks that have tenbagger potential and have a Zen Rating of A or B:

Hurry! Enter these 2 trades by EOD Tuesday The man behind THIS plan has used an odd twist on trading options for the past 20 years to rack up incredible profits... even using it personally to retire in just 10 years...with a $5.3 million "nest egg" that helped him sail worry-free through every Financial Crisis and market crash since... And now he's about to release his latest two trades... Click here to access your first two trades.

1. Digi International Inc (NASDAQ: DGII)

A large player in the Internet of Things (IoT) space, DGII is already looking to have a good year, and has a Zen Rating of A, putting it among the top 5% of stocks we cover. Specifically, reviewing its component grades, it has a B in Value, Growth, Financials, and Artificial Intelligence. This indicates a stock that exhibits signs of future growth and is currently undervalued.

While it is uncertain how the IoT will be used in the future or which products will take off, its continued growth and health are likely, and DGII will almost certainly branch out into other areas of everyday life.

2. BioMarin Pharmaceutical Inc (NASDAQ: BMRN)

Any Biotech stock is a major breakthrough away from that coveted tenbagger status, and while BioMarin does not have such a breakthrough to our knowledge, it still presents an undervalued opportunity to the right investor who is willing to consider it.

We’ve recently covered BioMarin Pharmaceutical as a great opportunity to buy the dip. It’s down -35.49% over the course of the year, and despite this, our system indicates it holds excellent value for the price (with a Component Grade of A for Value), and it has been regularly cited as a growth candidate by analysts and publications. Revenue exceeded expectations in Q2, and the company's cash flow is improving.

3. GreenBrier Companies Inc (NYSE: GBX)

Rail has dealt with some tough tracks as an industry in recent years, but that does not mean every railroad stock isn’t worth considering. Manufacturing cars, equipment, parts, and more alongside shipping-related services, GBX has steadily been on track for investors, and perhaps underconsidered.

The key point about GBX is that it is currently considered undervalued, with a Value Component Grade of A by our own Zen Ratings system. Estimates are rising, GBX is outperforming industry expectations, and it offers a reasonable dividend yield.
