AIG did a 20:1 reverse split on July 1, 2009. The stock, in the low 20's tanked to under $10/share. THEN to my amazement, the traders got involved with the stock. The price shot up to the 30's then 40's hit $50+ and traded between $30 to $50. It stands at $57.62 today 12/31/10.
In EXBX's case a 15:1 reverse split will give a float of 18.6 million. At the current closing price today of $.0052 that will convert to $.078/share. Traders will be able to whipsaw this stock up fast since the float is ONLY 18.6 million at a low price of $.078 to work with.
