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 Targa Resources (NYSE:TRGP). Even if this company is fairly valued by the market, investors would agree that generating consistent profits will continue to provide Targa Resources with the means to add long-term value to shareholders.

Targa Resources' Improving Profits

Targa Resources has undergone a massive growth in earnings per share over the last three years. So much so that this three year growth rate wouldn't be a fair assessment of the company's future. Thus, it makes sense to focus on more recent growth rates, instead. Targa Resources' EPS shot up from US$3.73 to US$4.86; a result that's bound to keep shareholders happy. That's a commendable gain of 30%.

It's often helpful to take a look at earnings before interest and tax (EBIT) margins, as well as revenue growth, to get another take on the quality of the company's growth. Despite consistency in EBIT margins year on year, Targa Resources has actually recorded a dip in revenue. This does not bode too well for short term growth prospects and so understanding the reasons for these results is of great importance.

Are Targa Resources Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a US$36b company like Targa Resources. But we do take comfort from the fact that they are investors in the company. We note that their impressive stake in the company is worth US$583m. Holders should find this level of insider commitment quite encouraging, since it would ensure that the leaders of the company would also experience their success, or failure, with the stock.

Should You Add Targa Resources To Your Watchlist?

You can't deny that Targa Resources has grown its earnings per share at a very impressive rate. That's attractive. With EPS growth rates like that, it's hardly surprising to see company higher-ups place confidence in the company through continuing to hold a significant investment. Fast growth and confident insiders should be enough to warrant further research, so it would seem that it's a good stock to follow. Don't forget that there may still be risks.
