Good one Lindy, I did not do my own financial news search.
Found out through a local brokerage after I was talking to someone at a Spy vs Spy store ( they sell listening-detection electronic equip. etc. )
It would be hard to prove a conspiracy or if this means anything. I checked the local library, New York Financial Times and it is valid.
I was using yahoo.com daily and calculating the closes for at least 2 years now. Top 30 and million of shares traded daily for these companies. After hours trades could be a factor in manipulating a final daily close.
