FTSE 100 slips as concerns about technology valuations weigh on shares
The FTSE 100 ended slightly lower on Tuesday after rising earlier in the day.
The London index closed down 0.1%, while the FTSE 250 edged up and the AIM All-Share fell.
Investors grew wary of technology valuations, including heavy spending on artificial intelligence without clear returns.
Technology shares also faced pressure after Asian chipmakers SK Hynix and Samsung Electronics fell, amid concern about advances by Chinese memory-chip maker ChangXin Memory Technologies.
The sell-off reflects fears that chip demand or high expectations could weaken, though some analysts said investors may move money into other sectors.
ASML is due to report results on Wednesday, offering investors a closely watched update from a major chip-equipment maker.
