I also noted the buy rating from S&P Capital Markets on WIN in one of it's reports prior to this passed earnings report (7/27/13). Yes, they have a $10 target (not $9), but they are NOT the only ones in setting that target price.
Thomson Reuters also shows the $9 range as a "mean" target, with $14.30 as the "high" target and $6.50 as the "low" end of that target range.
And, of course, in that Thomson Reuters report, that range comes from more than just 1 analyst. Thomson Reuters canvasses that 4 analyst rank WIN as a strong buy, 1 analyst ranks WIN as buy, 9 analysts rank WIN as a hold, and 4 analysts rank WIN as "reduce".
All of those analysts must have some guess as to a price target, and that is how they arrive at the target price "curve" (high, mean, low) in their report.
And as well, wouldn't you imagine that after the bond rating debacle in the wake of the housing collapse of 2008-2009 that S&P would risk getting caught with their hands in their pants manipulating some bond situation with WIN???
Honestly, it's a stretch; and I highly suspect that you would be lacking in proof of your hinted assertions, anyways.
