Investment trust Scottish Mortgage (SMT) could win promotion to the blue-chip FTSE 100 index at the end of March, potentially attracting a swathe of tracker funds to buy its shares.

The flagship investment trust of manager Baillie Gifford, Scottish Mortgage is currently valued at £4.7bn, second only to investment bank  Investec (INVP) in the queue to make the leap. This is substantially above the rough £3.5bn to £3.6bn valuations of the FTSE 100's current lowest ranked stocks, including outsourcer Capita (CPI), Dixons Carphone (DC.) and real estate business Intu Properties (INTU).

Every quarter FTSE reviews the constituents that make up its various indices based on market capitalisation.

If Scottish Mortgage is successful and joins the FTSE 100 it would be something of a rarity. Only Foreign & Colonial (FRCL) and Alliance Trust (ATST) are investment trusts to have been included among the UK blue-chips in the past, and neither currently is.
