April 23 (Reuters) - Australian shares ended marginally higher on Friday but recorded their first weekly loss in five, as a possible capital gains tax hike in the United States and surging coronavirus cases in parts of the world subdued risk sentiment.
The S&P/ASX 200 closed 0.08% higher at 7,060.70 points. The benchmark edged 0.04% lower for the week.
U.S. stocks dived overnight on reports President Joe Biden planned to almost double the capital gains tax, though broader Asian equities managed to shake off initial losses amid a lack of other major news.
