Tips for Trading in Japan: An Overview of Day and Swing Trading

Japan is a major player in the global financial markets, with a well-developed system of stock exchanges and a large securities industry. The Tokyo Stock Exchange (TSE) is the largest stock exchange in Japan and one of the largest in Asia by market capitalization. The TSE is home to many major Japanese companies, such as Toyota and Sony, as well as a number of foreign companies listed through the Mothers market for startup and high-growth companies.

In addition to the TSE, there is also the Osaka Securities Exchange (OSE), which focuses on derivatives trading, and the Nagoya Stock Exchange (NSE), which primarily lists smaller companies. Japan also has a thriving futures market, with the Tokyo Financial Exchange (TFX) being the most important center for trading financial derivatives in Japan.

With all the different exchanges in Japan, it is a thriving center for day trading and swing trading. While day trading involves opening and closing a position within the same day, swing trading involves holding a position for many days or a few weeks until a swing is completed. There are many different markets and instruments to trade, including stocks, futures, forex, commodities, and even cryptocurrencies.

Trading In Japan – Strategy, backtest and trading rules

Let’s end the article with a specific trading strategy and backtest.

The backtests are based on the cash index of the Nikkei 225, and thus it has limitations. The results might be different if you backtest the relevant futures contract (and not the cash index). Among other things, dividends are not included in the cash index, and thus the returns are lower compared to if dividends were reinvested.

The first strategy is a winter seasonal strategy that has worked well in the US markets. How has it performed on Japanese stocks?

Let’s define the trading rules:

  • We buy at the close on the first day of October, and
  • We sell at the close of the first trading of May.

We sell in May and go away until October.

Below is the results since 1965. The red line is our strategy and the blue line is buy and hold:

Clearly, our strategy has performed much better despite being invested only 56% of the time.

Below is the equity curve if you bought in May and sold in October:

You would have made a significant loss! Even during the bull market from 1965 until the bubble popped in 1990 would have resulted in tiny gains.

Let’s look at a second seasonal trading strategy: The turn of the month trading strategy. We buy at the close of the month’s fifth last trading day of the month, and we sell at the third trading day of the new month:

The strategy worked very well until 2010 but has since then performed poorly.

Understanding Japanese Market Dynamics and Trading Regulations

Japan has strict rules and oversight in place to ensure the integrity and stability of its financial markets.

There are some specific guidelines for insider trading and market manipulation, which are prohibited and can lead to serious penalties.
