Review likely to leave flagship index unchanged for first time since 2006
Thursday 06 Sep 2018 Author: Tom Sieber

As we went to press it was looking increasingly likely that the latest FTSE reshuffle would see no changes to the FTSE 100 for the first time in more than a decade.

These reshuffles can be significant and not just for the prestige associated with membership of the UK’s flagship index. It can also affect the flow of money into a stock, as, when it enters the FTSE 100, funds which track the index are compelled to buy.

We discussed in our 23 August issue, which focused on the FTSE 100, how these quarterly reviews of index membership work. As a brief reminder, companies qualify if they rank among the top 90 UK listed firms by market value and are eliminated if they fall to position 111 or below on the night before the review takes place – in this case close on 4 September.

At the time of writing, the lowest ranked FTSE 100 company was property listings site Rightmove (RMV) but it was still materially above the cut-off point for automatic demotion.


Whether the fact the FTSE 100 will remain the same for two consecutive quarters for the first time since 2006 is a sign of welcome stability or sterility is open to question.

Since the last reshuffle was determined at the end of May, the FTSE 100 has drifted, trading close to the 7,800 mark in early August but now just barely above 7,500.

It also implies mid caps are lacking the momentum to break into the top echelons of the market. This would fit neatly into a narrative of the FTSE 250, the pool from which future FTSE 100 firms are drawn, being negatively impacted by Brexit uncertainty due to a domestic bias.

However, as we discussed in our follow-up to the FTSE 100 feature last week, which looked at the FTSE 250 in detail, many of its constituents have international horizons.

The two companies which were knocking hardest on the door of the blue chip index, oil services firm Wood Group (WG.) and industrial pumps specialist Weir (WEIR) are both truly global businesses.

In the long-term there are still reasons to believe the FTSE 250 can continue its historically strong performance. Mid caps occupy a very healthy position. They are neither too small, and thereby lacking the scale required for a successful business, or too big and mature to generate meaningful growth.
