London Markets: FTSE 100 finishes with fourth straight loss as oil worries linger

U.K. stocks finished slightly lower Friday, with oil shares hindered by battered crude prices that helped leave the blue-chips index in the red for the week.

The FTSE 100

UKX, -0.20%

 closed down 0.2% at 7,424.13, with banks, consumer goods and basic materials companies ending lower. But gains for consumer services and utilities shares helped limit the benchmark’s loss.

The index has dropped for four straight sessions, FactSet data showed. It lost 0.5% over the week and has fallen for four consecutive weeks, the longest string since April.

On a weekly basis, the shares fell 2.9% and 2.2%, respectively.

“The enormous volatility in the oil market is unsettling investors around the world. The fear of falling inflation and reduced growth prospects is at the forefront of traders’ minds,” said CMC Markets analyst David Madden in a note.

“It is not unusual for us to witness rallies, but the big picture is that oil has been falling since March, and now the selloffs are becoming even more severe.”

Shell and BP shares each closed 0.1% lower on Friday, paring losses as oil prices clawed higher. But crude prices remained on course for a fifth straight weekly loss.
