Stocks that are expected to significantly grow their profitability in the future can add meaningful upside to your portfolio. Pacific Smiles Group and SomnoMed are examples of many high-growth stocks that the market believe will be upcoming outperformers. If a buoyant growth prospect is what you’re after in your next investment, I’ve put together a list of high-growth stocks you may be interested in, based on the latest financial data from each company.

Pacific Smiles Group Limited (ASX:PSQ)

Pacific Smiles Group Limited owns and operates dental centers under the Pacific Smiles Dental and nib Dental Care brand names in Eastern Australia. Established in 2002, and now run by John Gibbs, the company currently employs 800 people and with the stock’s market cap sitting at AUD A$261.43M, it comes under the small-cap group.

PSQ’s projected future profit growth is a robust 27.04%, with an underlying 29.01% growth from its revenues expected over the upcoming years. It appears that PSQ’s profitability may be sustainable as the fundamental push is top-line expansion rather than unmaintainable cost-cutting activities. This prospective profitability should trickle down to shareholders, with analysts expecting the company to generate a high double-digit return on equity of 31.26%. PSQ’s impressive outlook on all aspects makes it a worthy company to spend more time to understand. Should you add PSQ to your portfolio? Take a look at its other fundamentals here.

SomnoMed Limited (ASX:SOM)

SomnoMed Limited, together with its subsidiaries, produces and sells devices for the oral treatment of sleep related disorders in Australia and internationally. Started in 2004, and currently lead by Derek Smith, the company now has 300 employees and with the company’s market capitalisation at AUD A$187.61M, we can put it in the small-cap category.

SOM is expected to deliver an extremely high earnings growth over the next couple of years of 58.52%, bolstered by an equally impressive revenue growth of 81.87%. An affirming signal is when net income increase is supported by top-line growth. Since net income isn’t artificially inflated by one-off initiatives such as cost-cutting, we know this profit growth is more likely to be sustainable. This prospective profitability should trickle down to shareholders, with analysts expecting the company to generate a high double-digit return on equity of 23.57%. SOM’s bullish prospects on both the top and bottom lines make it an interesting stock to invest more time to understand how it can add value to your portfolio. Could this stock be your next pick?
