I think that the most recent increase in SP is due to significant buying by Fisher Funds who have been increasing their stake. This may or may not give other shareholders confidence. I don't regard it as a negative myself. Techies would say who cares, provided stops are in place, any change in sentiment towards MHI will be detected and appropriate action taken.

In situations like MHI I always remember Warren Buffett's comment that the stock market in the short term is a voting machine but in the longer term is a weighing machine.
