Today the FTSE100, 250 and smaller companies index have a slightly different look about them because of the quarterly promotion/relegation battle that goes on which can see each index change over time. Without going into the calculation that determines who gets promoted and relegated, these changes should be noted and if necessary acted upon by investors and traders.
For long term buy and hold investors it can be a big negative if the company that you hold gets relegated. Usually, the relegation is known well in advance, so it is possible to act before the change actually happens. Whether you act will depend on how you see the prospects for the company going forward. A few quarters back hedge fund manager Man Group was one of those relegated from the FTSE100 to the 250 index and since then its share price has continued to fall. It had been in freefall for some time prior to its relegation, so the writing had been on the wall that the company was facing difficulties.
On the other hand, if you hold a company that is promoted often the share price will rise as the bigger buyers come in to add to their positions. This probably is more the case with smaller companies promoted to the FTSE250, but also companies promoted to the FTSE100 might see some price rise as FTSE 100 funds will look to buy.
So, what changed today?
