As an investor, you should always be looking for growth. Share prices tend to follow a company's value, so investors should seek firms that are increasingly rising in value. Truly phenomenal stock market returns are made by holding superior companies that grow relentlessly for decades.
But to actually identify the best growth stocks, you can't just look for companies with the highest projected growth rates. After all, if the market starts to lose faith in the company's prospects, the fall can be horrendous. Just look at what happened to Crocs
The best growth stocks offer both huge upside potential and a margin of safety. As such, they should satisfy three conditions:
1. A good growth rate
All else being equal, fast growth is better than slow growth. But because of compounding, even relatively small changes in the growth rate can make a big difference to investors.

But to achieve truly great results, you need to look beyond growth estimates. One of the biggest blind spots for most growth investors is focusing on the growth rate, but ignoring the sustainability of that growth. This myopia was one of the main causes of the tech bubble. People started paying high prices for third-rate companies sporting high growth projections, but few competitive advantages. Such investors were hurt badly when the bubble popped and the market for the companies they invested in disappeared.
So you should pay as much attention to the competitive position of the business as you do to the rate of growth. eBay
Similarly, Wal-Mart has enjoyed incredible success by focusing on one important sustainable competitive advantage -- selling at the lowest possible prices. And shareholders have ridden that advantage to handsome profits. If you invested $1,000 in Wal-Mart in 1980, you would now have more than $275,000. Now that's great sustainable growth.
3. A good price
One of the biggest mistakes that investors make is paying too much for growth. Occasionally, you can pay a steep price, and strong sustained growth will bail you out. But it's common for investors to pay so much that it's almost impossible to make a decent profit, even if the growth continues.

So before buying a growth stock, make sure it's undervalued, or at least fairly priced. A discounted cash flow (DCF) calculation is a great way to work out the fair value of a growth company. If you don't know how, the Motley Fool Inside Value newsletter has an easy-to-use DCF calculator for subscribers. (A free trial is available.) With a few quick clicks, it can tell you what you're paying for, and help you avoid paying too much.
The Foolish bottom line
These three ideas are central to a value investment strategy. Value investors aren't just looking for unpopular stocks. If anything, like Warren Buffett, we prefer to purchase strong companies with excellent growth prospects, because we recognize that these companies are worth significantly more than weaker companies. At the same time, value investors also know that if you overpay for that growth, you're increasing risk while reducing potential profits.
The best growth stocks offer sustainable growth at a reasonable price. When you find this sort of stock, the long-term profits can be immense. It pays to constantly be on the lookout for such businesses, the kind that make up the core of our Inside Value portfolio.
