Use Finance Yahoo, search for the corporation Caterpillar (stock trading symbol: CAT), explore its "Analysis" data section, and then find and quote its Growth Estimates of "Next 5 years per annum" and "Past 5 years per annum". Provided that such growth estimates (made by Wall Street analysts who are interested in tracking this stock) turn out to be unbiased and accurate, shall we expect CAT's equity value to grow faster in next 5 years than in past 5 years, or to grow more slowly than before?
