Morrisons has been reinstated on the FTSE 100 following a rise in its share price, just three months after it was demoted.
The supermarket chain's share price fell by 11% between November and December, prompting its fall out of the group which contains the UK's largest listed companies.
Since its lowest point in December, however, Morrisons' shares have grown by around 68%.
Earlier this week, Morrisons announced that it had agreed a deal with Amazon to sell products to the online retailer's Prime and Pantry customers.
Morrisons is joined in stepping up from the FTSE 250 to the 100 by Informa, Mediclinic International and Paddy Power Betfair.
Sports Direct, Smiths Group, Hikma Pharmaceuticals and Aberdeen Asset Management all fall off the list.
Every three months, the stock market is reevaluated to reflect the changes in share prices.
