I again look at the stocks to judge how well the management runs a company. So, just go to Google Finance, type Canon Inc. (TYO:7751), then compare with Nikon (TYO:7731), and Nikkei 225. The year to date results are:
Canon: -22%; Nikon: +21%; Nikkei 225: -1%.
Despite all the chatter, Nikon is doing much better than Canon in a flat market (so please don't start talking of floods, earthquakes, and nuclear disasters).
My personal opinion (also looking at the quality of the latest products): Canon needs a new management.
