In the final second of trading on Friday, Anadarko Petroleum Corp. (APC) goes from a $90 stock and trades down to $.01, that is a penny a share before closing at $90.03. I am sure some buyers (computers) thought they were fortunate to pick up APC at one penny. On the contrary, the NYSE canceled trades executed below $87.56 per share.
This type of trading activity certainly weighs on investor confidence in the markets and is an issue that most certainly needs to be addressed.
