Introduction

These days’ setup devices in trading industry are network-programmed to reread info news. The programs are very much leeway of a highly sophisticated computerized automated trading system (Gagnon, 2013). It psychoanalyzes those estimable nifty words in the news based on algorithms fitted and does the trading accordingly. Stock traders can evaluate news trends to seize up public sentiment on a specific company or industry to spot a combination of sentiment plus trading activity, and trending over time (Foucault, Hombert, & Roşu, 2016). Leaked information to the high frequency trading (HFT) corporations is strings to the trading venue. HFT traders queen it over on an electronic order book in fractions of a second to fulfill trades using encyclopedic algorithms technology to decode signals from the upturning market mandate (like events and news) securing lots of quick buck (Brown, 2011). The consequences of the news declaration are computed in a simple linear regression:

(1) where,

  • JGIM.2018100102.m02 is the vector of returns

  • JGIM.2018100102.m03 is the vector of “surprise”

JGIM.2018100102.m04 is eccentric error correlating to announcement of news; JGIM.2018100102.m05 is regression intercept that claims shifts in returns and, finally, JGIM.2018100102.m06 is the effect of the news announcement. In spite of the instinct of simple returns, good deals of the financial literatures rely on logarithmic returns. Mathematically logarithmic returns denoted as,

Previous studies (Henry, 2008; Schumaker & Chen, 2009; Schumaker, Zhang, Huang, & Chen, 2012) triumphed in enacting connect between real time information and stock earning, however in Finnish HFT firms, it is not perceptible, which are just in startup phase. To hit this need, this research analyses how an event based trading strategy proposed by Aldridge, can enrich news tone as value drive to get lofty profit. We get quantitative evidence for alpha testing the event trading strategy in HFT firms in Finland. The question that we answer is how in newly developed HFT markets of Finland, the information-communicated impact in the illation of better trading strategies for generating alpha profit, without emphasizing need for speed “based on Aldridge event trading strategy.”

Specifically, this paper documents this feasibility in Finnish market.
