In recent years, many anomalies and patterns have emerged in the stock market, requiring investors to closely observe these trends. This blog will explain various regularities and tendencies in the stock market. We will cover important factors influencing the market, such as summer stock trends, the impact of presidential elections, and inflation concerns, providing insights that can help with investment decisions.
1. What Are Anomalies? “Regularities” in the Stock Market
Anomalies refer to “regularities” in the stock market. These are empirically observed patterns that cannot be theoretically explained but are known to occur repeatedly.
There are various anomalies in the stock market. Despite lacking theoretical grounds, these patterns or tendencies recur. For example, there might be a tendency for stock prices to rise during certain months or days of the week, or for prices to fluctuate during specific events or periods.
One famous anomaly is the investment adage “Sell in May and go away.” This American saying suggests selling stocks in May and not returning to the market until the second Saturday in September, known as St. Leger’s Day. Although there is no theoretical basis, this anomaly is born from empirical data showing this pattern repeats over time.
The next section will explain the summer doldrums phenomenon in the U.S. stock market and anomalies in the Japanese stock market during the summer. Understanding anomalies can provide valuable insights into market trends.
2. The Summer Doldrums in U.S. Stocks
The U.S. stock market also exhibits certain tendencies in the summer, known as the “summer doldrums.” This refers to the regularity where stock prices tend to decline during the summer.
This phenomenon has been observed through historical data. In fact, examining the monthly average returns of the S&P 500 index over the past 30 years shows negative returns in August and September, indicating the presence of the summer doldrums.
Several factors are considered responsible for the summer doldrums. One is the reduction in trading volume due to individual investors taking summer vacations. As people go on vacation during the summer, the number of active investors decreases, leading to lower trading volumes and slower price movements.
Additionally, the timing of corporate earnings announcements often clusters during the summer. Companies typically report earnings quarterly, but the summer is generally considered a quiet period, leading to fewer earnings announcements. With fewer earnings reports, investors have less information to base their decisions on, often leading to more conservative positions.
Furthermore, the relative lack of political and economic events in the summer also contributes to the summer doldrums. For example, major events such as presidential elections or Federal Open Market Committee (FOMC) meetings, which significantly impact the market, are less frequent, leading to slower price movements.
These factors combine to create a period of stagnation in the U.S. stock market during the summer, making it more prone to declines. However, the summer doldrums do not occur every year, as different factors may influence the market each year.
Investors need to be aware of the summer doldrums when predicting market trends and should make decisions based on historical data and current market trends. Given the expected decline in market activity during the summer, it is crucial to adopt a cautious approach and avoid aggressive trading.
3. Summer Anomalies in Japanese Stocks
Specific anomalies are observed in the Japanese stock market during the summer, where stock prices tend to be heavy and more prone to decline. Why do these anomalies occur in the summer?
3.1 Influence of the U.S. Stock Market
Summer anomalies in the Japanese stock market are influenced by the U.S. stock market. The U.S. stock market also tends to decline during the summer, and this summer doldrum phenomenon spreads to the Japanese stock market, causing similar patterns.
3.2 Impact of Summer Vacations
Many companies take summer vacations, reducing trading activity. This dulls the market’s vitality and restricts stock price increases. Additionally, fewer corporate earnings reports during the summer lead to decreased investor interest and trading volume.
3.3 Portfolio Rebalancing
During the summer, investors tend to review and rebalance their portfolios. Specifically, they reassess positions based on the stock movements and corporate performance evaluations from the first half of the year. Moreover, increased corporate earnings announcements during the summer also impact investor decisions.
These factors combine to create summer anomalies in the Japanese stock market. However, anomalies do not occur every year. Factors may vary, affecting the market differently, so caution is needed when making investment decisions.
4. Stock Trends During Presidential Election Years
Presidential election years exhibit characteristic stock price movements, presenting risks and opportunities for investors. Below is a detailed explanation of stock price fluctuations during presidential election years.
4-1. Summer Rally (Summer Stock Price Rise)
During presidential election years, a summer rally typically occurs from June to September. This is driven by optimistic expectations about the future president’s policies and the economic direction.
4-2. Market Caution Before the Election
As the election approaches in September and October, the market tends to be cautious. This is because the election results could change future policy directions, causing investor caution.
4-3. Post-Election Stock Price Rise
Once the election ends and the next president is confirmed, stock prices tend to rise toward the year’s end. This is due to the clarity in the president’s policy direction, easing investor concerns.
The stock price movements in presidential election years are significant for investors due to the market’s reaction to the clarity of future political and economic directions. However, past trends do not necessarily predict future movements. Investors need to carefully observe election activities and candidate behaviors to judge market trends.
Investors should recognize the risks and opportunities in presidential election years and closely monitor changes in election results and policy directions. Collecting and analyzing information is essential for accurately predicting market trends and evaluating risks and opportunities. Presidential election years are crucial for the market, and investors must respond sensitively to market movements.
5. The Impact of Inflation Concerns on Corporate Earnings
Inflation is a significant factor for the market, but recent corporate earnings reports have seen fewer mentions of “inflation.” The severe inflation issues of mid-2022 are gradually improving, now treated as a “concern.” This is a favorable sign for corporate earnings, contributing to stock price increases.
While inflation remains a concern for the market, the current risk is decreasing. Market predictions have become accustomed to factors like the situations in Ukraine and the Middle East, suggesting a low likelihood of worsening risks. Additionally, although intensified US-China relations due to the presidential election could potentially lower the market, the market is already familiar with former President Trump’s personality and policies, making it unlikely he would adopt policies that lower stock prices.
On the other hand, the S&P 500 might reach my target value by late 2024. Historically, the S&P 500 has experienced an average of three corrections of over 5% each year, and 2024 has already seen a 5.9% correction. A drop of about 5% is common in the market, often considered a buying opportunity historically.
In the stock market, inflation trends and corporate earnings are closely related. The environment has leaned towards monetary easing, with increasing earnings driving significant stock price increases. After hitting an earnings bottom in Q2 2023, earnings are expected to increase, with a projected 9.4% growth in 2024.
Inflation concerns and corporate earnings significantly influence market trends. Currently, the risk is low, and earnings are on an upward trend. Therefore, it is not surprising if the market experiences a correction of over 5%. For long-term investments, it is crucial to monitor inflation trends and corporate earnings.
Considering these points, inflation concerns and corporate earnings trends will be key factors in observing market trends up to and beyond 2024. Inflation concerns are improving, and earnings are on an upward trend. However, attention is needed on the results of the US presidential election and subsequent policy directions, as well as yen depreciation. It is essential to adopt a cautious attitude and maintain a long-term investment strategy.
Conclusion
There are various anomalies in the stock market, and understanding them is essential for investors. By grasping seasonal stock trends, such as the summer doldrums in U.S. stocks and summer anomalies in Japanese stocks, investors can make better investment decisions. Additionally, it is important to pay attention to the characteristic stock price fluctuations during presidential election years. Furthermore, the trends in corporate earnings and inflation concerns significantly impact the stock market, requiring careful evaluation. Based on this knowledge, it is crucial to develop a long-term investment strategy. In stock investing, it is vital to consider various factors comprehensively and accurately evaluate risks and opportunities.
