U.S. indices were trading lower Thursday despite slightly better-than-expected U.S. jobs data. Positive data has potentially raised concerns the Fed could eventually taper stimulus measures. Speculative retail trading in some names has also increased volatility.

• The Invesco QQQ Trust Series 1 (NASDAQ:QQQ) finished lower by 1.04% to $330.
• The SPDR Dow Jones Industrial Average ETF Trust (NASDAQ:DIA) finished lower by 0.1% to $346.02.
• The SPDR S&P 500 ETF Trust (NASDAQ:SPY) closed lower by 0.37% to $418.77.

Here are the day's winners and losers from the QQQ, according to data from Benzinga Pro.

Dollar Tree, Inc. (NASDAQ:DLTR), Intuit Inc. (NASDAQ:INTU) and NVIDIA Corporation (NASDAQ:NVDA) were among top gainers for the Nasdaq Thursday.

Tesla Inc (NASDAQ:TSLA), Baidu Inc ADR Class A (NASDAQ:BIDU) and Micron Technology, Inc. (NASDAQ: MU) were among the top losers in the QQQ Thursday.
