Toyota: Is this stock stupid, or am I?

I don't get it.

Toyota (TM) keeps getting bad news. Their accelerator petal sticks (not always but often enough to make the news circuit). They replace the defective parts...with parts that are still defective. They seem to "hide" information.

Yet their stock keeps rising.

I don't get it. Either these buyers are foolish, or I'm just plain dumb.

I know that Toyota has a really long-standing positive reputation for quality, but they're being beat by Ford (F) pretty often now. (For the record, Ford stock continues to do well, also. In fact, Ford stock has risen more dramatically than Toyota.) Within the auto industry, they are known to take longer to develop new car concepts, because they involve more people during those initial stages. Most of the time, this led to a high quality, high performing product.

However, this process also means that it will take longer to find a "fix" to this problem. The stock keeps rising like the problem is fixed, except that the problem is not fixed. Even Toyota is not sure when they will fully fix this problem.

This stock has risen over 10% during the last month or so. Has this company gotten 10% better?

I don't get it!
