본 논문에서는 인터넷 검색 추세와 주식시장 사이에 어떤 관계가 있는지를 알아보고자 한다. 관심 기업의 정보를 얻기 위하여 투자자가 인터넷 검색엔진을 활용하고 이것이 실제 투자로 이어질 수 있다는 가정에서, 기업에 대한 검색량의 변화가 해당 기업의 주가 및 거래량 변동과 어떤 관계성이 있는지를 실제 데이터를 통해 분석하였다. 검색량의 변화를 기초로 한 검색트렌드 투자전략을 대기업 그룹과 중소기업 그룹에 적용하여, 두 그룹의 수익률 등락과 주식거래량에 대한 상관관계를 분석하였다. 7년(2007년~2013년)간의 데이터를 기초로 KOSPI와 KOSDAQ 모두에서 검색트렌드 투자전략이 시장의 평균 수익률 이상을 실현하고, 대기업보다는 중소기업에서 더 투자효과가 높다는 결과를 얻었다. 검색량과 주식거래량의 관계 또한 대기업보다는 중소기업이 더 영향을 받는다는 것을 알 수 있었다.

In this paper, we develope a stock trading system that automatically buy and sell stocks in Kiwoom Securities' HTS system. The system is made by using Kiwoom Open API+ with the Python programming language. A trading strategy is based on an enhanced system query method called a Condition-Search. The Condition-Search script is edited in Kiwoom Hero 4 HTS and the script is stored in the Kiwoom server. The Condition-Search script has the advantage of being easy to change the trading strategy because it can be modified and changed as needed. In the HTS system, up to ten Condition-Search scripts are supported, so it is possible to apply various trading methods. But there are some restrictions on transactions and Condition-Search in Kiwoom Open API+. To avoid one problem that has transaction number and frequency are restricted, a method of adjusting the time interval between transactions is applied and the other problem that do not support a threading technique is solved by an IPC(Inter-Process Communication) with multiple login IDs.

The basis of cyber trading has been sufficiently developed with innovative advancement of Internet Technology and the tendency of stock market investment has changed from long-term investment, which estimates the value of enterprises, to short-term investment, which focuses on getting short-term stock trading margin. Hence, this research shows a Short-term Stock Price Forecasting System on Learning Agent System using DTA(Decision Tree Algorithm) ; it collects real-time information of interest and favorite issues using Agent Technology through the Internet, and forms a decision tree, and creates a Rule-Base Database. Through this procedure the Short-term Stock Price Forecasting System provides customers with the prediction of the fluctuation of stock prices for each issue in near future and a point of sales and purchases. A Human being has the limitation of analytic ability and so through taking a look into and analyzing the fluctuation of stock prices, the Agent enables man to trace out the external factors of fluctuation of stock market on real-time. Therefore, we can check out the ups and downs of several issues at the same time and figure out the relationship and interrelation among many issues using the Agent. The SPFA (Stock Price Forecasting System) has such basic four phases as Data Collection, Data Processing, Learning, and Forecasting and Feedback.

최근 인터넷의 보편화와 정보통신 기술의 발달로 인해 인터넷을 통한 정보검색이 일상화 됨에 따라 주식에 관한 정보 역시 검색엔진, 소셜네트워크서비스, 인터넷 커뮤니티 등을 통해 획득하는 경우가 잦아졌다. 특정 단어에 대한 키워드 검색량은 사용자의 관심도를 반영하기 때문에 다양한 연구에서 개별 기업에 대한 인터넷 검색량은 투자자의 관심도에 대한 척도로서의 사용가능성을 각광받았다. 특정 주식에 대한 투자자의 관심이 증가할 때 일시적으로 주가가 상승하였다가 회복하는 반전현상은 여러 연구를 통해 검증되어 왔지만 그 동안 투자자의 관심도는 주로 주식거래량, 광고 비용 등을 사용해 간접적으로 측정되었다. 본 연구에서는 국내 코스닥 시장에 상장된 기업에 대한 인터넷 검색량을 투자자의 관심의 척도로 사용하여 투자자의 관심에 근거한 주가변동성의 변화를 전체 시장 측면과 산업별 측면에서 관찰한다. 또한 투자자 관심이 야기한 가격압박에 의한 주가 반전현상의 존재를 코스닥 시장에서 검증하고 산업 간의 반전정도의 차이를 비교한다. 실증분석 결과 비정상적인 인터넷 검색량 증가는 주가변동성의 유의적인 증가를 가져왔고 이러한 현상은 IT S/W, 건설, 유통 산업군에서 특히 강하게 나타났다. 비정상적인 인터넷 검색량의 증가 이후 2주 간 주가변동성이 증가하였고 3~4주 후에는 오히려 변동성이 감소하는 것을 확인하였다. 이러한 주가 반전현상 역시 IT S/W, 건설, 유통 산업군에서 보다 극단적으로 발생하는 것으로 나타난다.

In recent years, information technological revolution of using Internet in the Stock Market has shown reconsideration of Securities and Exchange Law. Since the 1998 Taipei Conference, ILA have studied upon it and presented 6th Interim Report during the 2000 London Conference. This paper summarizes a part of the 6th Interim Report. The Internet has created a medium to which traditional principles of jurisdiction may not have full relevance. To understand the jurisdictional issues posed by this new medium, we should first review the traditional principles of jurisdiction under international, U. S. law and Other Countries law. In previous reports, the general principles of jurisdiction in international law have been described. These principles are, however, difficult to apply in the context of Internet and other forms of computerized securities trading. Regulators all over the world are trying to address and solve jurisdictional issues raised by the Internet. The traditional rules of jurisdiction in international law, grounded as they are on a geography-based approach, may be in the process of being undermined by the Internet and other global networks allowing for remote access to information and to markets.

금융 분야에서 주가예측연구는 거래 안정성 및 이익 실현 등을 목적으로 한다. 기존의 통계적 예측기법은 무작위로 예측한 결과와 정확도 측면에서 비슷하거나 낮은 예측 신뢰도 때문에 실제 거래 결정에 참고 되기 어렵다. 인공지능 모델은 데이터특성과 변동패턴을 학습해 예측하기 때문에 향상된 정확도를 달성한다. 그러나 장기간의 시계열 데이터를 사용해 주가를 예측하는 것은 여전히 어려운 문제이다. 본 논문에서는 K-means 클러스터링 기반의 데이터 증강 및 입력 시퀀스의 Window-size 별 정규화 기법과 시계열 학습에 특화된 LSTM 모델을 활용하여 안정적이고 신뢰성 있는 주가예측 방법을 제안한다. 이를 통해 더욱 정확하고 신뢰성 있는 예측 결과를 얻고, 나아가 시장 안정성에 기여할 뿐 아니라 높은 수익도 추구할 수 있다.
