FTSE 100 up 2% as rebound continues
(Close): London's leading share index ended the day 2.04% higher on Monday after Tokyo posted its biggest one-day rise since late 2008.
The FTSE 100 rose 116.68 points to 5,824.28, after a 3% gain on Friday.
That increase gave the firm's share price its biggest one-day rise since October 2013.
Bernstein analyst Andrew Wood said: "These were a phenomenal set of results. RB blew away consensus on every major metric."
British Airways owner IAG was another top riser, adding 5.2% to 504.5p.
Shane Oliver, head of investment strategy at AMP Capital Investors in Sydney, said: "Shares have become oversold again and due for at least a bounce which may now be getting under way. But with global growth worries remaining, it's still premature to say that shares have bottomed."
The FTSE was still 7% lower than it was at the start of the year and about a fifth below last April's record high despite a rebound over the last two sessions.
