Wall Street stocks finished a quiet session mostly higher on Thursday, concluding a holiday-shortened trading week that has included weakening economic data.

Reports earlier in the week showed a softening in the labour market, a contraction in the manufacturing sector and slowing growth in services.

The Dow Jones ended flat at 33,485.

The S&P 500 gained 0.4 percent to 4,105, while the Nasdaq advanced 0.8 percent to 12,087.

Markets will be closed on Friday to mark Good Friday, meaning that investors will have to wait until Monday to trade on important March employment figures.

US stocks spent much of Thursday morning in the red, but pushed into positive territory after Treasury bond yields eased.

Investors are becoming more hopeful that the Federal Reserve will hold off on additional interest rate hikes, in light of a cooling economy.
