London's FTSE 100 remained flat on Thursday, following two consecutive record-setting sessions, as weakness in industrial stocks offset gains in financials, while Tesco shares climbed after the supermarket giant lifted its annual profit outlook. Tesco rose 4.2% after raising its full-year profit forecast, buoyed by continued market share gains from rivals. "Tesco's broad offer to customers at all price-points is helping it to drive sustained market share gains," said Matt Britzman, senior equity analyst at Hargreaves Lansdown. In the financial sector, 3i Group advanced 3.1% following a Bloomberg News report that the private equity firm is exploring potential divestments of its assets, including French information technology maintenance provider Evernex. The gains in the stocks boosted the investment banking index by 1.6%.
