Can you guess the biggest American company in April 2010? In that month, when oil traded at $102 a barrel, it was Exxon Mobil (XOM). As suggested by that example, the list of the largest US firms has changed markedly over the subsequent decade. The movement reveals not only shifts in corporate fortunes, but also evolving investor attitudes.

Below is the list of the 10 largest American companies from April 2010. The chart contains each company's stock-market capitalisation, its price/income ratio, and its Morningstar investment style. (By price/income ratio, I mean the standard price/earnings ratio, but with the earnings adjusted by removing extraordinary items. Morningstar calls the resulting figure "normalised income").
