"Global Tech Rally Boosts Asian Shares, Yen Loses Ground"

Semiconductor shares rally globally, boosting Japan's Nikkei but leaving Chinese and Hong Kong stocks in the red due to a patchy economic recovery and disappointment over stimulus measures. Japan's strong performance is attributed to a weakening yen and a positive profit outlook for exporters, while European chip stocks struggle to escape a weekly loss. ECB President Christine Lagarde's comments on rate cuts and the Bank of England's retail sales data are expected to influence markets on Friday.
