3) (14 points) Whenever you buy or sell a stock, professional dealers collect a fee called the “spread.” 1 Although competition is supposed to keep spreads low, there is evidence that dealers conspire to keep spreads high. The table below shows the spread for certain stock trades on the NASDAQ national market in 1991. At that time, spreads were required to be in eighths of a dollar: 1/8 ($.125), 2/8 ($.25), 3/8 ($.375), etc .
