When nominal charts of the FTSE100 start looking like this:
Which are showing us being within 1% of the nominal 30 December 1999 record high of 6930, the chatter in the mainstream media about the potential to reach new highs kicks off.
So what do I think about the potential to reach new highs? Well I don’t actually even waste brain power considering it for a few reasons:
Let’s run the numbers. Firstly we’ll remove the excitement and normalise the data by:

Which are showing us being within 1% of the nominal 30 December 1999 record high of 6930, the chatter in the mainstream media about the potential to reach new highs kicks off.
So what do I think about the potential to reach new highs? Well I don’t actually even waste brain power considering it for a few reasons:
- The most important is that my investment strategy is no longer based on any form of emotion but is instead now purely mechanical. This was done because early on in my DIY investing career I realised that no matter how much energy I expended I actually had no idea whether the market was going to go up, down or sideways. A lot of people out there do claim to know but from what I can see most of these seem to make their money by commenting on it in the media, writing books on the topic or by selling investing newsletters. If they really do know why are they expending energy doing this rather than making a fortune trading with this great knowledge? I really do now believe that unless you have inside knowledge, which you can’t profit on legally, then they are all actually just like me. They have no idea.
- As I’ll show in this post the market is actually nowhere near a new high.
- Again, as I’ll show in this post, while I believe the market is slightly overvalued it’s still only in the bottom 17% of monthly valuations since 1993.
Let’s run the numbers. Firstly we’ll remove the excitement and normalise the data 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.
