why is this stock going down, page-52

I just don't understand that people can logically think that shares bought by A and then sold by B and then bought back by B and eventually sold by A is much different from A buying the shares and then selling them apart from the timing of the buy/sell transactions.
In simple math the scenarios can be described as below:
A - B + B - A = 0 ( A buys, B sells, B buys, A sells)
A - A = 0 (A buys, A sells)
and when A = equal to B you can break this down:
(A - B) + (B - A) = 0 = A - A = B - B = 0 = 0 = 0
A - B = 0 (A buys shares and B has sells the shares. You can add in that B sells the shares "short" to confuse the hell out of everyone, but no difference)
B - A = 0 (B buys the shares back and A eventually sells the shares)
The only issue is the timing when A eventually sells the shares. B selling the shares means the shares are sold sooner than A may have intended to sell the shares and then buys the shares back and A sells later. Other than timing, there really is no voodoo involved.
