Investors are often guided by the idea of discovering 'the next big thing', even if that means buying 'story stocks' without any revenue, let alone profit. But the reality is that when a company loses money each year, for long enough, its investors will usually take their share of those losses. While a well funded company may sustain losses for years, it will need to generate a profit eventually, or else investors will move on and the company will wither away.

So if this idea of high risk and high reward doesn't suit, you might be more interested in profitable, growing companies, like Duke Energy (NYSE:DUK). Even if this company is fairly valued by the market, investors would agree that generating consistent profits will continue to provide Duke Energy with the means to add long-term value to shareholders.

Are Duke Energy Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a US$83b company like Duke Energy. But we do take comfort from the fact that they are investors in the company. Indeed, they have a considerable amount of wealth invested in it, currently valued at US$114m. While that is a lot of skin in the game, we note this holding only totals to 0.1% of the business, which is a result of the company being so large. This should still be a great incentive for management to maximise shareholder value.

Is Duke Energy Worth Keeping An Eye On?

As previously touched on, Duke Energy is a growing business, which is encouraging. If that's not enough on its own, there is also the rather notable levels of insider ownership. That combination is very appealing. So yes, we do think the stock is worth keeping an eye on. It's still necessary to consider the ever-present spectre of investment risk.
