Why invest in US shares?

Some things are just too large to ignore and in investment terms, the US certainly falls into that category.

It is estimated that US markets account for around 55% of the world’s total (by way of comparison, the UK market represents about 4%).

It is astonishing to consider how US brands have become entrenched in our daily lives.

This might be in terms of leisure time (Netflix, Disney+), mealtimes (McDonalds), morning times (Starbucks) or indeed any time (Google, Amazon, Apple, Facebook).

US investing was traditionally most easily achieved indirectly in the UK – for example, within the FTSE100 an estimated 70% of earnings come from overseas and it was therefore possible to gain some exposure through this channel.

In addition, overseas investment was held back by “home bias”, that is the tendency to invest in one’s own country, usually because of familiarity.

Apart from overseas investment now being easily accessible, there is also the world of Exchange Traded Funds, or ETFs, which these days means that an investor can slice and dice investments in many ways, such as by index, by country, by sector or by region.

In addition, there are other compelling reasons to be taking a global view. Quite apart from different economies moving at different speeds at any given time, the generally accepted wisdom of diversification does not just apply to sectors, but to geographies as well.

About the US stock market

The New York Stock Exchange (NYSE) and the Nasdaq are the largest stock exchanges in the world with a market capitalisation of over US$25 trillion and US$19 trillion respectively (May 2022).

The main US stock indices – the Dow Jones, S&P 500 and Russell 2000 – all feature stocks listed on both exchanges. Whereas the Nasdaq Composite and NASDAQ 100 only feature companies listed on the Nasdaq.

Both the NYSE and NASDAQ are open from 9:30 am to 4:00 pm Eastern Time (2:30 pm to 9:00 pm UK time).
