A busy day for corporate earnings reports ended with major stock indexes higher, though not enough to prevent them from a third-straight monthly decline. 

The S&P 500 climbed 0.6% on Tuesday, to end October 2.2% lower. Every industry segment in the benchmark index rose, with real-estate companies, banks and utilities leading the way. Arista Networks paced the index, gaining 14% after the networking equipment company beat quarterly sales and profit expectations.
