Technology shares pushed the S&P 500 and the Nasdaq to record highs on Thursday as optimism grew over a coronavirus stimulus bill, helping markets look past signs of economic strain brought on by the Covid-19 pandemic.
Technology stocks were among the best performing S&P sectors and hit a record high as their perceived resilience through the virus outbreak drove increased buying.
Consumer discretionary stocks, a sector primed to benefit from fresh stimulus also hit a record high, while utilities and materials shares marked large gains.

"We also have the Federal Reserve buying almost a trillion and a half dollars worth of assets a year and they have promised to keep interest rates at zero for the next three years and that is also where the optimism comes from," said Mike O'Rourke, chief market strategist at JonesTrading in Stamford, Connecticut.
