The FTSE 250 and S&P 500 are both stock market indices that track a certain number of stocks in an exchange or country. The S&P 500 is 500 stocks on US exchanges, chosen by a committee. The FTSE 250 is the 250 stocks after the 100th stock on the London Stock Exchange when you order the companies on the exchange by their market capitalisation.
The S&P 500 and the FTSE 250 are collections of stocks from their respective exchanges – in the FTSE 250’s case, it’s a collection of stocks on the London Stock Exchange and in the S&P 500’s case, it’s a collection of US stocks.
Another difference is how each index is constructed. The stocks that make up the S&P 500 are hand-picked by the US Index Committee, which picks the leaders in 11 sectors. The FTSE 250 is constructed by data alone – companies need to have a premium listing of equity shares on the main market of the London Stock Exchange and must have a minimum free float of 10% (UK incorporated) or 25% (non-UK incorporated). The stocks are ordered by their market capitalisation – the top 100 stocks make up the FTSE 100 and the following 250 make up the FTSE 250.
The S&P 500 is made up of 500 stocks, while the FTSE 250 is just 250 stocks. The overall market capitalisation of the S&P 500 is significantly higher than that of the FTSE 250 because a lot of the companies in the FTSE 250 are smaller. The market cap of the S&P 500 is $36.7 trillion (£29.74 trillion), compared with the market cap of the FTSE 250, which is £419 billion.
As we mentioned above, the S&P 500 is worth more than 70 times the value of the FTSE 250. It holds twice the number of stocks.
The S&P 500 has a better diversified set of stocks. It has a lot of technology stocks, making up around 15% of the index, but it’s well spread across a number of sectors. The FTSE 250 has a number of financial companies and a small number of health care, utilities and communication stocks.
If you’re looking for diversification, you might decide to invest in both indices. This gives you additional global exposure.
