LONDON (MarketWatch) -- Stocks in the U.K. rose Tuesday, with shares of Standard Life PLC and Aggreko PLC each higher following financial updates.

The FTSE 100 index rose 0.4% to 332.50, on track for its first gain in five sessions.

Perched at the top of the index, Aggreko traded 3.6% higher as the power-generator provider said its interim dividend was raised 3% to 9.38 pence, from 9.11 pence a year ago.

Aggreko, which was a provider for the 2014 World Cup soccer tournament, also backed its view that full-year underlying profit will be at similar levels to 2013. Pretax profit in the first half of 2014 fell 10%, hurt by exchange rates.

Shares of Standard Life gained 2.3% after the insurer, which also manages funds, posted a 12% rise in first-half operating profit.

On the losing end of the index, stock in Meggitt PLC dropped 7.3% following the aerospace-equipment company's decision to revise its full-year view of its military division. Weaker-than-anticipated revenue in that division contributed to a 20% decline in first-half pretax profit.
