Investing is all about profits, and part of generating profits is knowing when to start the game. The old adage says to buy low and sell high, and while it’s tempting just to discount cliches like that, they’ve passed into common currency because they embody a fundamental truth. Buying low is always a good start in building a portfolio.The trick, however, is recognizing the right stocks to buy low. Prices fall for a reason, and sometimes that reason is fundamental unsoundness. Fortunately, Wall Streets analysts are busy separating the wheat from the chaff among the market’s low-priced stocks, and some top stock experts have tagged several equities for big gains. These stocks are trading low now – but the reasons are not necessarily bad for investors.We’ve used the TipRanks database to pull up the data and reviews on two stocks that are priced low now, but may be primed for gains. They’ve been getting positive reviews, and despite their share depreciation, they hold Buy ratings and show upwards of 60% upside potential.Digital Media Solutions (DMS)We will start with Digital Media Solutions, an adtech company which connects online advertisers with customers through performance-based branding and marketplace solutions. DMS boasts a powerful consumer intelligence database, which it uses to fine-tune customer acquisition campaigns – while offering advertisers accountability for the project budget.DMS went public in July of this year, via a merger with a special purpose acquisition company, Leo Holdings. The combination took the DMS name for the ticker, and initiated trading at $10 per share. The stock has been volatile since, and is currently down 27% since it started trading.Digital advertising is a huge – and growing – sector, worth $100 billion in 2019 and expected to reach $130 billion by the end of next year. DMS has a solid piece of that cash cow, and the Q3 numbers demonstrate that. Quarterly revenue hit a company record, of $82.8 million, which was up 10% sequentially and 44% year-over-year. Of that total revenue, the company saw a gross profit of $25.1 million, for a 30% gross margin. All in all, DMS’s first quarter as a publicly traded company showed strong results.Covering the stock for Canaccord is analyst Maria Ripps, who is rated 5 stars by TipRanks, and stands in the top 1% out of more than 7,100 stock analysts. “The company saw meaningful volume growth from both new and existing clients, with particular strength from its auto insurance business along with the eCommerce, education, and non-profit verticals… We continue to think investors will gradually come to appreciate DMS’ similarities with other leading digital marketing peers that trade at more premium valuations, and expect multiple expansion over time as the story becomes better understood,” Ripps noted.To this end, Ripps rates DMS stock a Buy, and her $15 price target suggests an upside of 106% from the current share price of $7.20.

The stock has an average price target of $14, which indicates a 92% upside potential. (See DMS stock analysis on TipRanks)ViaSat, Inc. (VSAT)From digital advertising we move on to digital networking. ViaSat provides customers with high-speed broadband access through a secure satellite network system. The company serves both military and commercial markets, meeting the growing need for secure communications links.The anti-coronavirus shutdown policies have particularly hard on ViaSat. This may sound counterintuitive, as online networking has been busier than ever, but a large segment of ViaSat’s business comes from the airlines, and with air travel first grounded and still facing depressed travel volumes, ViaSat’s shares have yet to recover from their February/March swoon.On a positive note – and one that is indicative of the essential nature of secure satellite communications in today’s networked economy – ViaSat reported $577 million in Q3 contract awards, representing a 29% yoy gain. For the year to date, the company has seen awards totaling $1.9 billion, which is up 5% from this time last year. The third quarter (the company’s fiscal Q2) revenues and earnings were somewhat mixed, reflecting both the increase in contract awards and the decline in airline business. Revenues were $554 million, down 6% yoy, but up almost 4% sequentially. EPS was 3 cents per share, beating the predicted 5 cent loss by a wide margin.JPMorgan analyst Philip Cusick writes of ViaSat: “[We] believe long-term growth levers remain intact highlighted by record segment backlog of $1.1b… We view ViaSat as a satellite innovation leader and believe the company’s future ViaSat-3 fleet will accelerate growth in satellite services over the coming years. At the same time, we see a long-term government systems tailwind driven by the company’s radio portfolio, mobile broadband, and SATCOM.”In line with his bullish comments, Cusick rates VSAT shares an Overweight (i.e. Buy), and his $60 price target implies ~72% upside on the one-year time horizon. (To watch Cusick’s track record, click here)Overall, the stock has 5 recent reviews, including 3 Buys and 2 Holds. Shares are priced at $34.14, and the average price target of $55 suggests a 61% upside potential from that level.
