The discount is related to the fall of the dow. As rqi holdings fall with the the fall of its stocks the shares of rqi become lower in value and its larger discount. This happens to most funds during a market fall. Thus a wider spread between nav and share price produces a larger discount in falling stock market times. When the market goes up the opposite will happen
I hear you but I think there is more to it than that. I have held closed end funds for decades and can say it not usual to see a discount grow from less than five % to close to 10 % in a week , despite a down and fractious market.
