Golden Rule #3. Stay Away From Low Volume Stocks.
Low volume stocks generally have high spreads and move extremely fast on low volume. Whatgoes up fast, will go down faster. If you are on the wrong side of a low volume stock trade yourlosses can be excessive. My only exception is if I got a story 4 minutes before the market close,and I knew the story to be exceptional, I would do a market buy.
Recently a news story hit the wires on a low volume stock and I advised a student to stay out.The stock went up 3 dollars, which was the exception. He was lamenting all day long that he didnot do a market buy at the beginning. The stock moved so fast from the initial rally price that amarket buy is the only way he could have gotten in. When you do a market buy you are trustingyour Broker to execute in a timely manner. In a fast moving stock your execution can be severalminutes from the time you place the order. You will get exercised at the top of the rally and notknow it. By the time you confirm the order you are down the 3 dollars. I know, I have done it,only once. I learned fast.
There is a funnel effect with hot stocks that prevent you from doing a fast market buy. Everyonewants in at once. My advice is don't play with excessively volatile stocks and low volume stockscan be just that. Loss control is the most valuable tool for any trader.
