In 1982 the Bureau of Labor Statistics (BLS) began modifying the method for calculating the Consumer Price Index (CPI). Economist John Williams at ShadowStats.com publishes an Alternate CPI that employs the method used by the BLS from 1913 to 1982.

A suggestion from a reader in Canada prompted me to create a real (inflation-adjusted) version of our Four Bad Bears chart using the Alternate CPI.

you can use the blue links at the top to compare the nominal, real, and alternate real declines. With this Alternate CPI, the Tech Crash and Current Bear have declines greater than the official real declines:

• The real decline of the Tech Crash was 58.3% versus the nominal 49.1%.
  
• The real decline of the Current Bear low is 56.3% versus the nominal 51.9%.
