So previously, they chose a wide range of 1600-2425 to end 2016. Now they narrowed the wide range to a manageable 1525 to 2200 to end the 2016.
So, previously they made a useless projection spanning 825 S&P500 points, and now can’t stand by even that so are coming up with a new range.
I can bet that if S&P500 drops to 1800 by Jun-2016, they will revise lower and if S&P500 rises above $2100 by that time, then they will revise higher.
My question is, what service are they providing to anybody by making such broad projections?
