Index fun (ds)

On a rainy afternoon I decided to learn a bit more about Index funds, partly to understand if they should play more of a role in my investing. I don't have any money invested in them currently, and wondered if I should simply consider them as a ready made portfolio...as usual it ended up needing a few diversions in order to satisfy my curiosity...

What is the stock market?
Obtaining a listing on a stock exchange essentially enables a business access to capital, and would also potentially raise their profile through a public listing. They start life on the stock market through an IPO - an Initial Public Offering or stock market launch during which investors can buy shares in the business. The London Stock Exchange runs several markets on which a company can be listed - the two most of us are interested in are the Main Market and the Alternative Investment Market (AIM). The AIM has a simpler admission process and lower fees so is typically used by smaller and early stage businesses, but some of the AIM constituents are household names and have a market capitalisation comparable to some businesses in the FTSE 100, e.g. Burford Capital, Abcam, ASOS and Fevertree.

The London Stock Exchange (LSE) is managed by the helpfully named London Stock Exchange Group - which is also a publicly traded company listed on the LSE. According to the LSE there are over 2600 listed on the Main Market, from over 60 countries, plus another 1000+ listings on the AIM. The LSE enables stocks to be traded, and publishes price information on it's stocks every 15 seconds during trading hours.

What is an index?
Indices are slices of the stock market, with some sort of overarching logic driving what is included in that particular slice. They are often used to measure performance of that particular collection of stocks, against which the performance of other funds and/or portfolios can be assessed. A few such indices are:
  • The MSCI world is an index using the share price of over 1600 business across the globe
  • The S&P 500 is an index of 500 of the largest market capitalisation companies listed on 3 US stock exchanges
  • The FTSE 100 is an index of the 100 largest market capitalisation companies listed on the London Stock Exchange
There are more indices than you can shake a stick at, against which you can measure the performance of your portfolio. 

Index funds
So, getting finally to the starting point, Index funds...most major investment providers have funds which track an index into which you can invest e.g. ishares or vanguard. An index tracker fund will be composed to mimic the index via a couple of methodologies - either directly holding the shares in exactly the weighting as the index, or taking a sample of these shares in order to reflect the same underlying performance of the index.

The index as a portfolio
The index I'll focus on, mainly due to familiarity and convenience is the FTSE 100, which is maintained by FTSE Russell, part of the London Stock Exchange Group. This is an index composed of the 100 shares listed on the LSE with the largest market capitalisation (market cap = number of shares x share price). Shell have two flavours of their shares, both of which are listed in the FTSE 100, so there are 100 companies making up the FTSE 100, but 101 different stocks listed.

The FTSE 100 isn't a portfolio that is static, it is reviewed and, potentially, changed quarterly. The review process is described here. Each quarter, at the time of the review, any shares not currently in the FTSE 100, that have a market cap that puts them in the 90th position in the FTSE 100, or above, gets included in the index, and the shares with the lowest market cap are removed from the index. And any shares in the FTSE 100 that are valued at the 111th position in the wider FTSE All Share or below are removed from the FTSE 100, and are replaced by the shares outside the FTSE 100 with the largest market cap. For example as at June 2019, Hikma Pharmaceuticals and Easyjet hit the conditions for removal, whereas JD Sports and Aveva met the conditions for inclusion, a nice summary of this can be seen here.

Working on the assumption that share price performance more or less reflects the underlying performance of the business, we can see struggling business being cut from the portfolio, and high performing businesses being included. In the month of June 2019, we see two companies being promoted that are embracing technology, one a software company, the other a clothes retailer with a great ecommerce offering. From a portfolio management point of view this feels very much like cutting losers, and keeping winners. Since the Index does this rebalancing every quarter, so too do the funds tracking them.

Portfolio composition
My personal portfolio composition can be seen here. My aim is to mainly invest in defensive dividend paying stocks. How does the FTSE 100 measure up in this regard, there is plenty of information on the index here, I've taken the chart below from the Vanguard FTSE 100 tracking fund :
Vanguard FTSE 100 UCITS ETF sector composition
Vanguard FTSE 100 UCITS ETF Sector Composition (May 31 2019)
And below is a comparison from FTSE Russell between the FTSE 100 and the FTSE All Share:
FTSE Russell index comparisons
FTSE Russell index comparisons
Taking the Vanguard summary stats, it is clear there is a good chunk of the FTSE 100 portfolio that is very cyclical - Financials, Oil & Gas, Basic Materials and Industrials. These amount to around 56% of the FTSE 100. Add in another 3% for Utilities exposed to a potential risk of nationalisation (or at least being used as a political football in the UK), and there is getting on for 60% of the index that I would prefer to not be invested in. Which is not to say I wouldn't invest, but have a preference to put my money into less cyclical businesses, that offer some distinct competitive advantage other than price.

In addition it's difficult to see where the growth is going to be generated. We've seen from the US and China how technology is driving their stock markets, there is precious little of this in the FTSE 100. I'm sure these companies will eventually float to the top, assuming they are not acquired and absorbed into other business before they get there; as at June 2019, Microfocus and Sage are the two "technology" companies. This compares to technology making up around 21% of the S&P 500.

So, does it matter how the FTSE 100 is composed? Well, for example, since BP and Shell account for around 17% the oil price is going to push around the index valuation considerably. If some headline hits the banking industry - that's 12% of the index. At the other end of the index, if Sage had a significant increase in price it would make little difference to the index as both they, and Microfocus, combined make up less than 1% of the index.

Although the FTSE 100 is a slice of the stock market of businesses listed in London, as the LSE Issuer Services report shows, only about 29% of the revenues of the 100 listed businesses are actually from the UK. So there is an inherent currency risk too - stocks list on the LSE in Sterling, so revenues taken outside the UK need to eventually be reflected in a GBP stock price. This has probably proved something of a boon for a number of companies over the last few years as the Brexit omnishambles has kept Sterling depressed vs. both the Euro and the Dollar.

The bottom line
The FTSE 100 closed at 6754 on June 16th 2014. 5yrs later on June 16th 2019 it closed trading at 7345, an 8.8% increase. It's Price to Earnings ratio is around 14, so may be on the cheap side with potentially more upwards movement on the way, and the dividend yield on the Vanguard tracker mentioned above is 4.76%, which might also reinforce the idea that the FTSE 100 currently looks a bit undervalued.

The S&P 500 closed at 1962 on June 16th 2014. 5yrs later on June 16th 2019 it closed trading at 2886, a 47% increase. It's PE is around 19, and the dividend is 1.67%. Maybe the index is expensive, with little scope for upwards movement.

The FTSE 100 is not structured in a way I find especially attractive, too heavily focussed on cyclical businesses, particularly commodities and financials. However, although the dividend yield is attractive, I think there are individual businesses within it that look more attractive investments.
