Why Is the Consumer Price Index Controversial?
-The U.S. Bureau of Labor Statistics (BLS) produces the Consumer Price Index (CPI). The monthly publication of this number is the most widely watched and used measure of the nation's inflation rate.
From an investor's perspective, the CPI, as a proxy for inflation, is an important component used to estimate the total return on an investment or portfolio of investments.
Nevertheless, there has been debate for some years about whether the CPI overstates or understates inflation, how it is measured, and whether it is an appropriate proxy for inflation. Economists do not agree on how inflation should be measured.
