Does F5 Networks (NASDAQ:FFIV) Deserve A Spot On Your Watchlist?

Like a puppy chasing its tail, some new investors often chase 'the next big thing', even if that means buying 'story stocks' without revenue, let alone profit. And in their study titled Who Falls Prey to the Wolf of Wall Street?' Leuz et. al. found that it is 'quite common' for investors to lose money by buying into 'pump and dump' schemes.

In contrast to all that, I prefer to spend time on companies like F5 Networks (NASDAQ:FFIV), which has not only revenues, but also profits. While that doesn't make the shares worth buying at any price, you can't deny that successful capitalism requires profit, eventually. While a well funded company may sustain losses for years, unless its owners have an endless appetite for subsidizing the customer, it will need to generate a profit eventually, or else breathe its last breath.

F5 Networks's Earnings Per Share Are Growing.

The market is a voting machine in the short term, but a weighing machine in the long term, so share price follows earnings per share (EPS) eventually. That means EPS growth is considered a real positive by most successful long-term investors. It certainly is nice to see that F5 Networks has managed to grow EPS by 18% 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 smiling.

I like to see top-line growth as an indication that growth is sustainable, and I look for a high earnings before interest and taxation (EBIT) margin to point to a competitive moat (though some companies with low margins also have moats). F5 Networks maintained stable EBIT margins over the last year, all while growing revenue 3.8% to US$2.2b. That's a real positive.

Are F5 Networks Insiders Aligned With All Shareholders?

Since F5 Networks has a market capitalization of US$8.4b, we wouldn't expect insiders to hold a large percentage of shares. But we are reassured by the fact they have invested in the company. Indeed, they hold US$23m worth of its stock. That shows significant buy-in, and may indicate conviction in the business strategy. Despite being just 0.3% of the company, the value of that investment is enough to show insiders have plenty riding on the venture.

Is F5 Networks Worth Keeping An Eye On?

You can't deny that F5 Networks has grown its earnings per share at a very impressive rate. That's attractive. I think that EPS growth is something to boast of, and it doesn't surprise me that insiders are holding on to a considerable chunk of shares. Fast growth and confident insiders should be enough to warrant further research. So the answer is that I do think this is a good stock to follow along with.

Of course, you can do well (sometimes) buying stocks that are not growing earnings and do not have insiders buying shares. But as a growth investor I always like to check out companies that do have those features. You can access a free list of them here.
