One simple way to benefit from the stock market is to buy an index fund. But if you pick the right individual stocks, you could make more than that. Just take a look at Lifeway Foods, Inc. (NASDAQ:LWAY), which is up 77%, over three years, soundly beating the market return of 51% (not including dividends).

Since the stock has added US$9.3m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...'

Lifeway Foods became profitable within the last three years. So we would expect a higher share price over the period.

A Different Perspective

While the broader market gained around 36% in the last year, Lifeway Foods shareholders lost 12%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. However, the loss over the last year isn't as bad as the 10% per annum loss investors have suffered over the last half decade. We'd need to see some sustained improvements in the key metrics before we could muster much enthusiasm. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too. Consider risks, for instance. Every company has them, and we've spotted 2 warning signs for Lifeway Foods you should know about.
