A one cent move from 22 cents to 23 cents is a mere 4.5%. You'd have to risk a greater than 20K investment to make $1K. The stock moves in low volumes so the PPS is highly vulnerable to selling pressure, and with a snakeoil pyrmaid scheme like this, there's always a good chance that the boom will drop and the stock will head south, leaving short-term traders holding the bag.
It's not impossible to make some chump change trading YGYI short-term, but it's unnecessarily risky, and this is a far cry from touting YGYI as a reasonable long-term investment, which it clearly isn't.
Of the myriad stocks that one can speculate on, there's no reason to fixate on YGYI. The only reason that some people here do so is that they're YGYI distributors, not real investors, and they're stuck because they exercised poor judgment.
