Robust, high-growth companies such as NetComm Wireless are appealing to investors for many reasons. They bring about a strong upside to your portfolio, and less downside risk as opposed to financially challenged companies. Below I’ve put together a list of great potential investments for you to consider adding to your portfolio if growth is a dimension you would like to firm up.

NetComm Wireless Limited (ASX:NTC)

NetComm Wireless Limited develops and sells broadband products for telecommunications carriers, core network providers, system integrators, and government and enterprise customers worldwide. NetComm Wireless was established in 1982 and has a market cap of AUD A$174.13M, putting it in the small-cap stocks category.

NTC is expected to deliver an extremely high earnings growth over the next couple of years of 69.02%, bolstered by an equally impressive revenue growth of 90.61%. 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 positive return on equity of 18.44%.
