NewsScope is a machine-readable news service designed for financial institutions that make their money from automated, event-driven, trading. Triggered by signals detected by algorithms within vast mountains of real-time data, trading of this kind now accounts for a significant proportion of turnover in the world’s financial centres.
Reuters’ algorithms parse news stories. Then they assign “sentiment scores” to words and phrases. The company argues that its systems are able to do this “faster and more consistently than human operators”.
Millisecond by millisecond, the aim is to calculate “prevailing sentiment” surrounding specific companies, sectors, indices and markets. Untouched by human hand, these measurements of sentiment feed into the pools of raw data that trigger trading strategies.
