The Bid/Ask Spread. The bid/ask spread is the difference in price between the bid and ask. In active stocks the bid/ask spread is typically $0.01, for example the bid is $10.05 and the offer is $10.06. The attached chart example shows a Level 2 in the SPDR S&P 500 ETF.
Cost of Investing. The bid/ask spread is an additional cost of buying or trading stocks on top of the commissions charged by your broker. Since you buy at the higher ask price, you would have a loss equal to the spread if you sold right away and the stock price had not changed.
