RE:Consolidation - What give?
I found this discription on Horizons site.
As a general rule, a consolidation would occur with unit values at or lower than $4. Lower priced securities require a relatively higher number of shares to be traded to establish the same dollar value position. As a result, investors paying brokerage commissions on a per share basis would incur higher transaction costs. As well, brokerage firms typically will not allow securities trading at prices under $3 to be marginable.
