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. Unfortunately, these high risk investments often have little probability of ever paying off, and many investors pay a price to learn their lesson. Loss making companies can act like a sponge for capital - so investors should be cautious that they're not throwing good money after bad.

So if this idea of high risk and high reward doesn't suit, you might be more interested in profitable, growing companies, like Fox (NASDAQ:FOXA). While profit isn't the sole metric that should be considered when investing, it's worth recognising businesses that can consistently produce it.

Fox's Earnings Per Share Are Growing

If a company can keep growing earnings per share (EPS) long enough, its share price should eventually follow. So it makes sense that experienced investors pay close attention to company EPS when undertaking investment research. It certainly is nice to see that Fox has managed to grow EPS by 25% per year over three years. As a general rule, we'd say that if a company can keep up that sort of growth, shareholders will be beaming.

One way to double-check a company's growth is to look at how its revenue, and earnings before interest and tax (EBIT) margins are changing. The good news is that Fox is growing revenues, and EBIT margins improved by 4.0 percentage points to 20%, over the last year. That's great to see, on both counts.

Are Fox Insiders Aligned With All Shareholders?

It's said that there's no smoke without fire. For investors, insider buying is often the smoke that indicates which stocks could set the market alight. That's because insider buying often indicates that those closest to the company have confidence that the share price will perform well. However, insiders are sometimes wrong, and we don't know the exact thinking behind their acquisitions.

We did see some selling in the last twelve months, but that's insignificant compared to the whopping US$4.7m that the Executive Chairman & CEO, Lachlan Murdoch spent acquiring shares. The average price paid was about US$39.06. Big purchases like that are well worth noting, especially for those who like to follow the insider money.

On top of the insider buying, it's good to see that Fox insiders have a valuable investment in the business. We note that their impressive stake in the company is worth US$147m. This comes in at 0.7% of shares in the company, which is a fair amount of a business of this size. This still shows shareholders there is a degree of alignment between management and themselves.

Does Fox Deserve A Spot On Your Watchlist?

If you believe that share price follows earnings per share you should definitely be delving further into Fox's strong EPS growth. On top of that, insiders own a significant piece of the pie when it comes to the company's stock, and one has been buying more. Astute investors will want to keep this stock on watch. Still, you should learn about the 1 warning sign we've spotted with Fox.
