This stock is an excellent example of how the market isn't pricing in the reward reduction. It's currently trading at a 125 week ROI assuming no difficulty changes. If I could short it, I would.
Note: this is nothing against your company, just your shareholders are acting very irrationally.
It is naive to assume that the price of a bond is based just on its payout. If that were the case then Treasury bonds paying 0.25% per year would be practically worthless.
