By Sruthi Shankar Sept 29 (Reuters) - European stocks rose on Wednesday after one of the worst market routs this year, with investors picking up beaten-down shares of technology sector, while chip equipment maker ASML gained on upbeat earnings forecast. ASML Holding NV ASML.AS, one of the key suppliers to computer chip makers, rose 1.8% after raising financial targets. After smooth gains in the past seven months, stock markets have faced volatility in September with investors nervous about major central banks withdrawing pandemic-era stimulus amid signs of higher inflation.
