Market players making market activity in a sluggish world wide economy betting against Jap Electric Co. Don't any of those jokers know Nikon will never die and especially due to their questionable gamesmanship? I am immortal.
These days, share prices can be quite detached from the actual performance of the company. Short-sellers may be betting against the future performance of the Nikon (it's true Nikon profits are suffering).
Or not. They may be trying to elicit a sell response from the market so they can snap up more actual stocks of the company at a cheaper price. Nobody really knows.
If you are not a stock broker or bought tons of Nikon shares, are these even a topic worth wasting on compare to going out there to use your Nikon gear you already bought that keeps depreciating every day in value?
