Strong gains in the financials sector weren't enough to buoy all of Wall Street on Thursday, June 29, as another tech selloff weighed on the Nasdaq. 

The S&P 500 slipped 0.27%, the Dow Jones Industrial Average fell 0.14%, and the Nasdaq declined 0.8%.

Financials were the best performers on Wall Street after the dividend and stock-buyback plans of all 34 of the country's biggest banks won approval from the Federal Reserve, but it was a close call for some.

Capital One Financial Corp. ( COF) was asked to resubmit its proposal to address "weaknesses" in its planning process.

( GS) , Morgan Stanley ( MS) , State Street Corp. ( STT) and JPMorgan Chase & Co. ( JPM) .

The "stress tests" of the 34 large financial institutions, known as the Comprehensive Capital Analysis and Review, were set up in the aftermath of the 2008 financial crisis, when a number of financial institutions increased payouts despite rising defaults in the $15 trillion U.S. mortgage market and dour assessments from analysts.

(FB) , Amazon.com Inc. (AMZN) , Apple Inc. (AAPL) , Netflix Inc. (NFLX) , and Alphabet Inc. (GOOGL) ), have been under pressure after a steep run-up in the year to date.
