LONDON/MILAN, May 4 (Reuters) - European stocks fell on Wednesday, hovering near three-week lows, with shares in Dialog Semiconductor slumping after it cut its revenue outlook and BHP Billiton stock dropping on news of a lawsuit filed against it in Brazil.
The pan-European FTSEurofirst 300 index, which fell 1.7 percent on Tuesday, was down 1 percent by 1341 GMT.
"We may have the odd move higher, but we remain in a longer-term bear market," Zurich-based ACIES Asset Management's chief investment officer, Andreas Clenow, said.

Dialog slumped 10 percent after the maker of chips used in Apple and Samsung Electronics smartphones cut its revenue outlook as it reported a 58-percent drop in underlying operating profit.
DZ Bank analyst Harald Schnitzer said although the revision was not a surprise "uncertainty surrounding (Dialog's) future performance is growing".
Mining stocks fell as weak copper prices hit the sector.
