Abstract:
The spread of COVID-19 is making a serious impact on the world economy. As policies to maintain economic activities have been implemented in a timely manner, many stock markets have regained its stock prices to pre-corona levels, although there are still strong opinions that the prices don’t reflect the real economy. This paper describes results of statistical analyses of daily historical data concerning Dow Jones Industrial Average (DJIA), Nasdaq Composite Index (NASDAQ), France Stock Index (CAC), German Stock Index (DAX), Shanghai Composite Index (SSEC) and Nikkei Stock Average (Nikkei). In general, these stock prices plunged for approximately 20 days before the trading day that marked the lowest price, and increased for the next 25 days. Reflecting the fact that the world economies are tightly related to each other, it is confirmed that stock price fluctuations under study generally show the same trend. We propose a technical indicator defined by the difference between a stock price and moving average. The results of experiments show that the indicator predicts short-term trends with a slight time lag.
