Consensus Outlook
Forecasters, reflecting the price of oil, see December import prices falling 1.2 percent after an oil-deflated 1.6 percent plunge in November. Export prices, which fell a sharp 0.9 percent in November despite a price bounce for farm products, are expected to slip another 0.3 percent.
Relative Performance Index
Econoday's RPI provides a handy summary measure of how an economy has recently been evolving relative to market expectations.
A reading above zero means that the economy in general has been performing more strongly than expected and vice versa for a reading below zero. The closer is the value to the maximum (+100) or minimum (-100) levels, the greater is the degree to which markets have been under- or over-estimating economic activity.
A zero outturn would imply that, on average, the market consensus has been correct. Note too that the index is sensitized to place extra weight upon those indicators that investors consider to be the most important.
Definition
Import price indexes are compiled for the prices of goods that are bought in the United States but produced abroad and export price indexes are compiled for the prices of goods sold abroad but produced domestically. These prices, which exclude tariffs and taxes, measure underlying inflationary trends in internationally traded products. Why Investors Care
