"Growth and value investing are joined at the hip."

You think that's crazy? Tell Warren Buffett. He's the one who said it, not me.

But, of course, I think he's right. I'm writing today because the largely semantic differences between value and growth often gets lost, even here at the Fool.

Head to head
That's because there is a temptation to equate growth investing with speculation, as fellow Fool Chuck Saletta did here.

But that's just wrong. Real growth investors don't bet on companies whose "sky-high" expectations make it nearly impossible to produce meaningful returns. More often, gurus like Ron Baron of Baron Growth invest in firms whose superior growth characteristics have yet to be recognized or rewarded by the stock market.

Value investors, on the other hand, look for stocks that trade for less than their intrinsic value, or stocks that the market has unfairly undervalued. Often, these firms are experiencing problems that investors believe to be temporary.

Both strategies, although seemingly different on the surface, operate on the premise that the market has mispriced a stock.

The obvious won't help you
History proves that you'll need more than math to discern what, exactly, is mispriced. Take the market's 10 best stocks. Hansen Natural was trading for 29 times trailing earnings 10 years ago. A value investor simply looking for stocks with price-to-earnings ratios below the market average would have missed the 250-bagger to come.

Same with Chico's (NYSE:CHS), an 87-bagger, which was trading for 21 times earnings a decade ago. Celgene, a 61-bagger, hadn't produced a penny of profit in its history.

The very best value stocks
Stock market myth says that only value investors zig as others zag. Hogwash. Baron has been buying shares of Cheesecake Factory (NASDAQ:CAKE), Edwards Lifesciences (NYSE:EW), and Ameristar Casinos (NASDAQ:ASCA), none of which looks "cheap" by the numbers. Yet Baron, by investing where others won't, has crushed the market.

David Gardner can claim similar success. When last summer obliterated the returns of his Motley Fool Rule Breakers service, David remained committed to owning businesses whose capacity to rule high-growth industries leads to huge gains in cash flow.

Today, more than 10 stocks in the Rule Breakers portfolio have at least doubled, including biotech Myriad Genetics (NASDAQ:MYGN). No surprises there. It was misunderstood. It was cheap relative to its growth potential. In short: It was a value stock.

Rules breaking, fortunes in the making
So, please, don't make the mistake of confusing growth investing with speculation. You'll miss out on just about all of the market's best value stocks -- the misunderstood multibaggers in the making -- if you do.
