Trade remained mixed across Europe on Tuesday with a number of small moves, despite major FTSE 100 companies beating profit outlooks in their quarterly results.

In London, the FTSE 100 (^FTSE) moved lower by 0.5% by the close in London. The German DAX (^GDAXI) edged down 0.2%. The French CAC (^FCHI) was close to flat.

FTSE 100 drivers HSBC (HSBA.L) and BP (BP.L) beat profit forecasts on Tuesday morning. BP shares jumped more than 2.5% on the opening bell to lead the index.

HSBC posted a 79% rise in pre-tax profit of $5.78bn (£4.1bn) for the first quarter of 2021, up from $3.21bn a year ago. Despite the good results, the bank still said that there is a “a high degree of uncertainty.”

Higher oil prices helped support BP's outlook — the oil major said it would start buying back shares in Q2.

"We’re into the meat of earnings season proper now with 173 S&P 500 companies that account for around half the market capitalisation are reporting this week," said Neil Wilson, chief market analyst for Markets.com.

"So far so good: of those that have already reported, revenues are up 10% on average, while earnings are up by a third. A stunning turnaround from last year’s pandemic washout, driven by a combination of massive fiscal stimulus, extraordinarily accommodative monetary policy and a vaccine-led cyclical bounce back of epic proportions."

Across the world, new lockdowns in Turkey and the worsening COVID-19 situation in India could shake investors' confidence. Oil prices retreated on Monday on the prospect of fresh restrictions in India — one of the world's biggest importers of the commodity.
