FTSE 100 vs FTSE 250

FTSE 100 vs FTSE 250
One is seeing record highs but does that mean you should invest?

If you see a news update about the UK economy, the odds are you’ll hear someone reference the FTSE 100’s performance.

The blue chip index, composed of the 100 biggest publicly listed companies in the UK, is seen as the best litmus test for how the country’s stock market is performing.

But this can end up being misleading. FTSE 100 firms may trade on the London Stock Exchange but most of their business is outside of the UK.

In fact, only about 23% of FTSE 100 company revenues are derived from the country they’re listed in. So even if it’s a good way of gauging the health of the UK’s equities markets, investing in the FTSE 100 is not necessarily a great way of getting exposure to the local economy.

FTSE 250 vs FTSE 100

Contrast that with the FTSE 250 and you get a bit of a different story. 

Companies in the index, which contains the next 250 largest listed firms in the UK after the FTSE 100, get 41% of their revenues from within the country. And historically that figure has hovered around the 60% mark.

This may explain why the index has performed comparatively well in the past six months.

Unlike the FTSE 100, the FTSE 250 has now recovered from last year’s covid-induced crash and is trading at record highs.

The double whammy of Brexit uncertainty and the coronavirus meant there has been a huge amount of gloom surrounding UK stocks, even prior to the pandemic.

But with an EU deal in place and a return to normal life on the horizon, investors are starting to find the UK economy a bit more attractive again.

Bouncing back

Despite this growing interest, stocks listed here are still trading at much lower valuations than they are in most other major economies — at least on a price to earnings basis. 

Consultancy firm Yardeni Research recently published data showing UK stocks are trading at an average forward price to earnings (P/E) ratio of 13.3.

By comparison, US stocks averaged 22.7 and Japanese stocks 17.2. 

Shares in companies listed in the EU’s Economic and Monetary Union were a tad higher than the Japanese ones, with an average forward P/E ratio of 17.8.

You can take this in a couple of ways. 

A higher P/E ratio often means investors believe a company is going to grow and thus justify its current valuation with higher future earnings. 

So those numbers could mean people don’t have a lot of faith in the growth potential of UK companies. 

On the other hand, lower P/E ratios are often a sign that investors have unfairly neglected a certain market or company. 

As an extreme example of this, the founder of Amtelon Capital, an asset manager that invests in Iranian stocks, said he started the fund after he saw stocks trading with P/E ratios of 4 or 5. The Iranian stock market went on to be one of the best performing in the entire world not long afterwards.

Somewhere in the middle

The UK is obviously not Iran. Luckily we’re not under US sanctions here and we aren’t ruled by a fairly autocratic government. 

But the reason Amtelon was able to do so well there was because investors tarnished Iran’s whole market with the same brush. Things are bad there, most of them seem to have thought, so its stocks must be bad too.

A similar train of thought has been guiding lots of investors with regard to the UK over the past few years. 

Even though many FTSE 100 firms have practically no exposure to the UK economy, people haven’t been buying them because they still see the index’s performance as being tied to the local economy.

Having said that, we have to admit that some of the long-term prospects of the UK’s blue chip firms aren’t looking great.

Less than 2% of the FTSE 100 is made up of technology companies, compared to almost 25% in the S&P 500, a major US index.

Conversely, energy companies like BP and Shell make up around 15% of the FTSE 100. Tobacco companies BAT and Imperial Brands also have a close to 5% weighting in the index.

Looking at those stats, it’s easy to see both sides of the coin. Investors may be undervaluing FTSE 100 firms but a lot of its major constituents also don’t look likely to provide the sort of exciting growth we’ve seen in US tech stocks over the past two decades.

More room for growth?

The FTSE 250 is a little better in this regard. 

Tech stocks make up just over 3% of the index and consumer staple and discretionary goods, which have both seen some good growth over the past decade, comprise about 25% of it.

This may explain why the index has managed to outperform the FTSE 100 by some margin over the past 5 years. Since April 2016 the FTSE 250 has risen by 34.8%. The FTSE 100 only rose 12.5% during the same period.

To be fair, that picture looks a little different when you factor in dividend payments. If you had reinvested FTSE 100 dividends during that five year period, you’d have seen a total return of 35.1%. The equivalent figure for the FTSE 250 was 51.1%. 

Of course, a big part of those gains for the FTSE 250 have also come recently and could be due to greater enthusiasm about the UK economy.

For now that could make sense but then the UK economy may also not turn out to perform as well as people are expecting it to. At the same time, the global economy could recover faster than people think it will and give more of a boost to FTSE 100 firms.

In short, there are pros and cons to both indices. Investing in something like an ETF that tracks either index is a simple way to get exposure to them. But just be aware of the differences between the two — and what the future holds for them — before you do.
