Trading AheadUnethical and illegal trading by specialists or market makers.
A specialist may buy a stock for themselves from Dr. John Q. Public even though a better price is available from another seller. The specialist can view bid and ask prices and then manually mis-match them, or see ahead to a less favorable price. It happens in this editor’s experience, by observing how long it takes for a stop order to execute after the stop price was reached.
This practice is a form of shimming.
Trading ImbalanceA situation where a large block of stock is put up for sale, but not enough buyers are available for purchase, and a market maker is unable to buy the imbalance. Lightly traded and tightly held stocks are considered temporarily illiquid during such imbalances.
On occasion, a trading halt is put into place until enough buyers are available to purchase the deficit. On rare occasion, a handful of buyers can buy the stock at a huge discount if the stock was not halted during the imbalance.
On the New York Stock Exchange, large stocks usually have a “delayed open” for such imbalances, as a trading specialist will fill the order by lining up buyers for the block, and then open trading for the stock for the day.
Triple Witching HourThe final hour of trading on a Friday when stock index futures, stock index options, and stock options all expire. This happens on the third Friday in March, June, September, and December. See Quadruple Witching Hour.
