‘Twas the day after Thanksgiving – Black Friday, as it is often called, in the retail trade – and it appears Missourians headed to the stores and shopping malls to make those big and not so big holiday purchases. The events on Wall Street are often an indication of how Black Friday sales are going. And, if Friday’s stock market goings-on are to be believed, a lot of people headed to the big department stores for those 5 a.m. bargains. Traders apparently liked what they saw, and when the markets shut down after half a day, the Dow Jones Industrial Average, the Nasdaq, and the Standard & Poors index were all up. The Missouri Retailers Association points out that sales for the Christmas shopping season can account for up to 60 percent of a retailer’s annual sales – and Black Friday’s cash register receipts set the pace for the holiday season.
