"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 get 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 Peter Doyle and Murray Stahl of Kinetics Paradigm 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. American Eagle Outfitters was trading for 28 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 32-bagger to come.

Same with Chico's (NYSE:CHS), a 69-bagger, which was trading for 21 times earnings a decade ago. Frontier Oil, a 33-bagger, hadn't produced a penny of profit for three straight years at the dawn of 1997.

The very best value stocks
Stock market myth says that only value investors zig as others zag. Hogwash. Doyle and Stahl have been buying shares of NYSE Euronext (NYSE:NYX), Leucadia National (NYSE:LUK), and Nasdaq Stock Market (NASDAQ:NDAQ), none of which looks cheap by the numbers. Yet Kinetics Paradigm, by investing where others won't, is a solid market-beater.

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 digital jeweler Blue Nile (NASDAQ:NILE). 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
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.
