I disagree that a post on internet forums alter a share price. Wouldn't even be a coded signal to dump, people would pick up the auld Alexander Graham Bell for that or tap his buddy across the trading desk.
Even if someone posted that PTSC has just agreed an $800m dollar deal with five major co's people would check the source of the information.
The share price fluctuations are going to make the traders plenty plenty plenty money. Great news recently for PTSC, we await news now of MMP Licence Settlements & Royalties.
