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.
As with bid and ask prices, the spread between bid and ask yields is wider when markets are illiquid and narrower when there is a lot of trading activity. Most investors are more familiar with trading in the stock market than in the bond market. The concept of bid and ask yields might sound complex in theory.
