Have been following PYM for months and can only side with TheBanker in saying that the SP is "being weighed down big time". Would really like to understand why someone sells/dumps right before the closing bell. This has happened on repeated occasions. Is there an advantage (to some party or other) for our SP to be diminished before US investors wake up?? Or is this a ploy to keep PYM's credit rating suppressed? I see the word "manipulation" used a lot on other threads but who gains from this end of day play? Can one of the trading gurus please provide some insight?! Irrespective of games, ..... I'm convinced that the true value of PYM will shine through.
