ARMONK (New York): Retailers of electronics and appliances in the US are expected to grow sales of those products by $953 million in June, July and August, according to an analytics-based forecast produced by IBM (NYSE: IBM). The forecast represents a four percent increase compared with the same period last year.

The IBM forecast is produced using statistical and analytical software to evaluate both the long-term sales trend and seasonal peaks. IBM consultants use these predictive techniques to help clients improve performance by addressing complex issues of supply and demand. These techniques also aid clients in planning product mix, new store locations, staffing and advertising spend.

Here's the month to month breakdown of the forecast (numbers in billions):

"Retailing is an extremely dynamic industry, affected by powerful factors ranging from the economy to fast-moving trends," said Dr. Michael Haydock, Partner, Business Analytics and Optimization Services, IBM Global Business Services. "Analytics give retailers a window into the future that enables them to make better decisions, increase return on investment and provide customers with the products they want."

In producing the forecast, IBM uses economic data gathered by the U.S. Census Bureau. The data is derived from a survey of retail establishments engaged in electronics and appliances as their major line of business. Products include TVs, cell phones, personal computers and tablet computers, radios and stereos, refrigerators, dishwashers, ovens, and other devices.
