The other technology revolution in trading and investing is driven by qualitative, textual and relationship information. The IBM computer Watson’s overwhelming Jeopardy victory demonstrated how good machines can get at this. News analysis is a focus of language technology in finance. This paper includes event studies and US portfolio simulation results are shown for “pure news” signals applied over 2006-2009, and a true out of sample period in 2010, which showed alpha in excess of 10%/year.
