(Adds companies for investors to review.)NEW YORK ( TheStreet) -- Almost three-quarters of S&P 500 companies that have reported third-quarter results have beaten analysts' estimates. Still, Wall Street is trimming forecasts for next year. S&P 500 companies are now expected to post almost 8% growth in 2012 earnings per share. But material and industrial stocks will be the driving force, generating growth of 12% to 16%, says Morgan Stanley. When the global economy begins to recover, those so-called cyclical stocks will benefit the most. Material and industrial stocks are already showing early signs of growth in the U.S., making it a good time to consider buying their shares.
