Stocks slide amid lower oil prices, mixed earnings; Apple drops 3% On Sales Disappoint

``U.S. equities fell on Wednesday, pressured by a mixed bag of quarterly corporate results and falling oil prices... Apple posted a better-than-expected quarterly profit Tuesday after the close, but fell short of expectations on sales. The company's cash hoard also hit a record of $238 billion. Meanwhile, Boeing and Coca-Cola, two other Dow components, posted results Wednesday that beat estimates on both the top and bottom line. Other firms that reported Wednesday include Six Flags, Mondelez and Biogen.''
