The Nasdaq Composite closed at its highest level since July, as Big Tech stocks continue to recover after a growth and valuations scare over the summer.
The tech-dominated index rose 0.2 per cent to 18,573.13, its second-highest closing level ever and about 0.5 per cent away from its all-time record.
The gains in tech were not enough to offset declines elsewhere in the broader market, however, with the benchmark S&P 500 slipping 0.1 per cent on Tuesday.
Big Tech stocks were among the worst hit during a bout of market volatility in July and August, but have outperformed since the Federal Reserve cut interest rates last month.
