Nowcast and Tokyo Stock Exchange Start Proof of Concept Testing using Alternative Data - Limited Public Distribution of Mid/Small Cap Analyst Report in English -

Nowcast Inc. ("Nowcast", CEO Masashi Tsujinaka), a subsidiary of Finatext Holdings Ltd. (CEO Ryota Hayashi) who handles analysis of big data, especially in the currently rising niche of alternative data, and Tokyo Stock Exchange, Inc. ("TSE", President & CEO Koichiro Miyahara) will commence Proof of Concept (PoC) testing under the Proof of Concept Program for Utilizing Securities Data (*1) on limited public distribution of mid/small cap stock analyst reports in English by using alternative data (*2).

This PoC will start from November 2019 with distribution of reports to participants for three months. The purpose is to verify whether distributing reports could propose new investment opportunities and contribute to reducing the lack of information for investors.

Background of this PoC

With the globalization of financial and capital markets, the presence of institutional investors from overseas is also increasing in the TSE market. Due to this change, there is a demand for information disclosure in English in order to ensure information disclosure to overseas institutional investors and to allow for cross-referencing across the globe. However, analysts’ coverage of small and medium cap stock is relatively lower compared to that of large caps.

With the aim of solving these problems, Nowcast and TSE will start providing analyst reports that use alternative data. Both will take advantage of natural language processing (*3) and the knowledge of analysts (*4) to compose a large number of reports that would not be possible to accomplish with only ordinary humans, and in turn try to solve the problem of qualitative and quantitative lack of English information on mid/small caps.

Summary of Provided Content

In this PoC, we will use alternative data and pick up listed companies that are likely to get attention from investors. We will automatically generate English reports with short comments about the selected companies based on financial statements and other relevant materials disclosed by said companies. In addition, for stocks that are considered to be of high interest to investors, detailed reports will be drafted separately and provided to the participants.

In order to prepare English reports, we will also utilize the machine translation engine (*5) that is under research and development by JPX.
