Appreciate the answer, Buffalo.
I was aware of the volume issue and have been avoiding stocks with an average daily trading volume of less than 1 million. My intention is to trade even higher volume companies as I make enough money to negate the percentage lost by brokerage fees (given my averages, I estimate that I need about $7000 in cash assets before I can start trading stocks with market value over $5 per share).
"Pink sheets" is a new term to me but after reading up on them, it appears that I am not trading any pink sheet stocks. My understanding is that stocks with ".pk" ending their symbol are pink sheet stocks.
I really appreciate the insight. Is there anything else that you can think of?
