Should You Be Adding Tetra Tech (NASDAQ:TTEK) To Your Watchlist Today?

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 as Peter Lynch said in One Up On Wall Street, 'Long shots almost never pay off.' Loss-making companies are always racing against time to reach financial sustainability, so investors in these companies may be taking on more risk than they should.

So if this idea of high risk and high reward doesn't suit, you might be more interested in profitable, growing companies, like Tetra Tech (NASDAQ:TTEK). Now this is not to say that the company presents the best investment opportunity around, but profitability is a key component to success in business.

Tetra Tech's Earnings Per Share Are Growing

If you believe that markets are even vaguely efficient, then over the long term you'd expect a company's share price to follow its earnings per share (EPS) outcomes.

It certainly is nice to see that Tetra Tech has managed to grow EPS by 30% per year over three years. If growth like this continues on into the future, then shareholders will have plenty to smile about.

Careful consideration of revenue growth and earnings before interest and taxation (EBIT) margins can help inform a view on the sustainability of the recent profit growth. While we note Tetra Tech achieved similar EBIT margins to last year, revenue grew by a solid 22% to US$3.4b. That's encouraging news for the company!
