Here's a useful table:
Note: Stock price appreciation April 1993 (date of TM's New York listing) to present adjusted for dividends and splits but not spin offs.
Toyota is the low cost producer. Although Ford's operating margin looks half way decent, bear in mind that this excludes interest expense which is very high for Ford. The assets/equity ratio is key here. The American producers are struggling under a triple liability burden. The pension and healthcare benefits explosion has been much written about, but far worse is the effect of their financial indebtedness.
Toyota's overall leverage is about ten times less than its rivals.' GM and Ford have effectively been subsidizing their customers with cheap credit and this has further worsened their inferior competitive position in that it overstates their already low operating margins.
Toyota vs. GM or Ford would make a classic hedged pair trade. Toyota on its own does not look that cheap or expensive at around 16 times their own forecast for this year's earnings.
