Navistar was in my financial feed a couple weeks ago, but I wasn't able to get to looking at it until today.
What an interesting chart! How long can a bear market endure? How about since late 1980?
From what I can discern, NAV peaked in its WAVE-ONE in late 1980 and has been working its way down to a WAVE-TWO low since then...
It appears to have one more down move remaining in a wave-e:C:TWO that could take it down to the ~3 range... twt.
P.S. Navistar is the holding company for International (buses), so as long as schools need buses, it seems it will have business.
