You conveniently ignore the critical question of whether there is solid information behind the "pump" or not. For example, if KBLB ever announces that their worms have produced pure spider silk you can bet your bottom dollar it will be "pumped" to the skies. But you can also bet your bottom dollar that the SP will never again (barring some unrelated major disaster) get anywhere near as low as the point it takes off from (probably with a gap up that never closes).
IMHO this whole concern about "pumping" thing is a "guilt by association" approach. What it does is make even good news appear to be somehow a problem because "pumping" is occurring. "Pumping" always occurs when a penny stock has good news. Are you trying to say that good news is bad for the company/stock?
The question is not whether or not "pumping" is going on, but what information is being put out about the company and how valid it is and what the implications are. IMHO, concern about "pumping" is just a diversion.
Your approach (trading around the pump)also has the same basic flaw that chain letters do.
The early ones make money. The ones that follow lose.
In the trading business the individual investor is playing at a considerable disadvantage. Level II is the best you can get. The insiders (market makers, those with fast trunk direct connections to the exchange computers (so that their orders get there before yours and get the trade even when made at the same time) etc., get Level 3. And much better charts (ones that show all the data so they can read the pattern and compare it to similar ones months or years ago (can't do that when all you get earlier than last week is daily figures).
Someone has to lose in this game and guess who it usually is.
Just like a chain letter, those who have just joined (i.e. sold hoping to buy back cheaper) have a large interest in getting others to follow them (so someone else can be the late one that loses money).
IMHO.
PS I also find it very amusing that some of the same people who express great concern about "pumping" going on also advocate trading around it.
