(Reuters) -Nasdaq beat first-quarter profit expectations on Thursday as the exchange operator benefited from higher market volatility and strong demand for its fintech and solutions products, sending its shares up 1% before the bell. To diversify its revenue streams, the company has been expanding outside its market-sensitive core activities of trading and listing to products that help financial institutions navigate compliance requirements and safeguard against financial crimes. With markets remaining volatile in the first quarter amid economic uncertainty and the trade dispute between the United States and China, companies have been spending on products that help safeguard them from market volatility.
