Sharecast - Gold miner Endeavour was the standout gainer on the index as gold prices were boosted by a flight to safety.
Mondi (LON:MNDI) and Hargreaves Lansdown (LON:HRGV) were also in the black, having fallen a day earlier on the back of updates.
Rentokil Initial (LON:RTO) was under the cosh for the second day in a row, after saying on Thursday that its full-year performance in North America was set to be "marginally below" its previous expectations, citing "near-term market uncertainty".
InterContinental Hotels Group fell after it reported a big slowdown in RevPAR - a key performance measure used in the hospitality industry - in the third quarter as growth softened across all regions. However, the group said it still expects a "very strong financial performance" this year.
HSBC was knocked lower by a downgrade to ‘market perform’ at KBW.
