The S&P 500 ended the trading day down 0.74%, the Dow Jones Industrial Average fell 0.98%, or 178 points, and the Nasdaq slipped 0.73%.

A special Eurogroup meeting was held Wednesday with hopes to present a deal at the European Union Summit on Thursday, but no deal was reached, according to CNBC. Talks have escalated as Greece faces a crucial repayment to the International Monetary Fund by the end of the month.
