Let’s now run the numbers. The last time we looked at this dataset was on the 30 April 2013.
FTSE 100 Price
In early morning trade today the FTSE 100 was priced at 6,160. That is a fall of 4.5% when compared with the 01 May 2013 Price of 6,451. It’s still 17.1% above the 01 June 2012 Price of 5,260. How this pricing compares with history can be seen in the chart below.

This is a similar chart to that which you will see in many places within the mainstream media. Let’s now remove the sensationalism by:
- Correcting the chart for the devaluation of the £ through inflation. For this dataset I use the Consumer Price Index (CPI) to devalue the £.
- Plotting the Pricing on a logarithmic scale as opposed to a linear one. By using this scale percentage changes in price appear the same.
Looking at the chart this way reveals the FTSE 100 in a very different light. That light shows that the compound annual growth rate (CAGR) in today’s £’s has only been 1.7%. Correct it by the Retail Prices Index (RPI) and that falls to 1.0%.
