U.K. stocks edged slightly higher on Monday. The benchmark FTSE 100 index rose 0.26%, or 14.49 points, to 5,666.28. The FTSE All-Share Index advanced 0.15%, or 4.31 points, to 2,947.36.
"The market is making a pause after last week's declines," said Bruno Ducros, a fund manager at CamGestion in Paris, which oversees about $4 billion in stocks. "All the better, but I'm not sure it will last. We expect volatility until Spain's bond sale on Thursday."
