In case you missed it, October was a, by recent standards, a banner month for auto sales. We are still at levels that during normal times would indicate serious problems or would otherwise be dismissed a freakishly low, but the fact that the automakers are profitable at these sales levels speaks well to the performance of their stock prices.
Ford (F), has had quite a nice run as well all know, but it still is not that richly valued. According to Marketwatch data, it's trading at a little over 7x forward earnings estimates, which are probably too low. Even after rising so much so fast, it's still not exactly that rich. Now, will you make 10-fold on your money again? Certainly not. However, a decent 40% from here is certainly conceivable.
Looking elsewhere in the automotive sector to automotive parts suppliers, I don't see so many good buys, however. Borg Warner (BWA) is looking a little pricey, at least relative to the market. Johnson Controls (JCI), a personal favorite of mine, looks good from here, but not better than Ford. I kind of like Dana (DAN), but it still doesn't exactly scream "buy".
All of them have had impressive one year runs, however.
