LONDON (The Deal) -- European stocks ceded modest gains Thursday morning ahead of a crunch meeting of eurozone monetary policy makers that investors are looking to for action to spur growth.

By late morning in London, the FTSE 100 had slipped 0.50% to 6,115.82, while in Frankfurt the DAX edged down 0.02% to 9,721.39. The CAC 40 in Paris yielded 0.14% of its value to fall to 4,419.55.

It may also expand its monthly bond buying program. Stocks may fall if its eventual action -- or the accompanying commentary from central bank boss Mario Draghi -- falls short of the hoped-for stimulus measures.

But also in Frankfurt, fertilizers producer K + S slumped 6% after missing analysts' revenue and earnings expectations in 2015. For 2016, it predicted a moderate decline in revenue and a significant deterioration in earnings this year.
