Comment and opinion for retail investors in the UK

Watching Brief – September 2021

1st September 2021 by Mark Potter 2 Comments

Pottering About

We are entering a hazardous time of year for investors, so an ‘accident black spot’ sign has just flashed, as we happily motor along with our portfolios running sweetly and the speedometer reading some 10% above the legal speed limit which seems fine given the conditions.  The speed being our enthusiasm for risk!

According to Investopedia, the (ancient) Dow Jones Industrial Average has declined 0.8% on average in September months since 1956 and the S&P500 (more realistic a measure) has declined 0.5% on average over an unspecified period.  This is said to be a global pattern, not just affecting US markets. In fact, the NASDAQ, established in 1971, has performed much the same.

Autumn is a time for reflection and any final actions in the long run up to Christmas!

In more recent years, September sell offs have been less significant but that might just be because trading is now more dependent on algorithmic decision making and less on human behaviour and the summer holiday season of the Northern Hemisphere!

Does that mean we should be selling equities and sitting on cash (or more cash for most of us)? 

I would suggest that would introduce potential market timing errors, although banking profits, especially if you need a return from your assets to maintain your lifestyle or fund some purchases, must make sense.
