Key PrePromo Variables to keep in mind:


Stock Split within last year: 20 to 1, 50 to 1, 75 to 1 etc.
Outstanding shares 300M and up.
Idea target from history for a large promo is 25:1 Forward Split with 250M+ OS within past several months.
Major Press Release issued prior to the pick (many times are Afterhours)
Press releases behind issued closer together than prior history.
Name change/symbol change is great initiator to begin developing story.
Disclaimers on all marketing publications on potential promo size.
Addresses and affiliates on marketing material such as emails, hard mailers, etc to connect puzzle pieces into who is behind promo.
Possible fakeouts such as RARS, AWSR etc. that had smaller OS yet came at same time that hype was peaking for the next APS pick.  
A Forward Split of 30:1+ with Outstanding Shares of 300M+ sitting at relative low share price compared to historical with a major promo pick expected days or a couple weeks away is worthy to consider speculative starter position (especially when PR of symbol change/name change is announced with all the above variables in play)
