Stocks that are expected to significantly grow their profitability in the future can add meaningful upside to your portfolio. Beacon Lighting Group and Triton Minerals are examples of many high-growth stocks that the market believe will be upcoming outperformers. Investment in growth companies can benefit your current holdings, whether it be in established tech giants or undiscovered micro-caps. Here, I’ve put together a few companies the market is particularly optimistic towards.

Beacon Lighting Group Limited (ASX:BLX)

Beacon Lighting Group Limited operates as a specialist retailer of lighting products in Australia. Established in 1967, and now run by Glen Robinson, the company size now stands at 1,000 people and with the company’s market capitalisation at AUD A$333.13M, we can put it in the small-cap stocks category.

BLX is expected to deliver an extremely high earnings growth over the next couple of years of 11.96%, driven by a positive double-digit revenue growth of 18.13% and cost-cutting initiatives. It appears that BLX’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 26.68%. BLX’s impressive outlook on all aspects makes it a worthy company to spend more time to understand. A potential addition to your portfolio? I recommend researching its fundamentals here.

Triton Minerals Limited (ASX:TON)

Triton Minerals Limited engages in the exploration and pre-development for graphite in Mozambique. The company was established in 2006 and with the stock’s market cap sitting at AUD A$71.60M, it comes under the small-cap group.

TON’s projected future profit growth is an exceptional triple-digit, with an underlying triple-digit growth from its revenues expected over the upcoming years. It appears that TON’s profitability may be sustainable as the fundamental push is top-line expansion rather than unmaintainable cost-cutting activities. TON’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. Want to know more about TON?
