The accumulation is not to "kill" the stock or bankrupt the company. MoneyMakers - Make Money on the down and upside. PPHM has been under accumulation for a very long time with no real catalyst to move it up and with SunRise set back was just another opportunity to finish a long campaign of controlling the float (possibly by warehousing and parking) method under the radar while keeping the PPS down not to bring attention to institutions or retailers. IMO retailers are the ones that catch on first as statics show that individual trading has been increasing over time. The price is being held down to shake out weak hands (psychological warfare) see psychology of trading. Many longs are aware and are adding knowing this shouldn't be under $1 based on AVID growth alone. While others are doubting and see no future.
The reason to accumulate a substantial amount of shares is because the tide will turn and PPHM will start a very very long bullish campaign (IMO towards becoming a BP). (If not bought out at a high premium) but yet we are constantly told PPHM is dead and management is criminal.
MMs if they are controlling a substantial amount of shares will start a campaign of selling over time at a higher price as buyers will start paying more realizing the true value. The Psychology is then reversed but buyers will pay more and more. This is were MMs will make many multiples and retail longs that hold their shares will reap the rewards.
IMO I see multiple partnerships, licensing of platform and manufacturing growth.
Silence right now can be a "quiet period." Short interest has decreased and the lid will crack open.
