What are stock market anomalies?
Stock market anomalies are market inefficiencies or predictable price movements that deviate from the Efficient Market Hypothesis (EMH). According to EMH, all information is already reflected in stock prices, making it impossible to outperform the market consistently. However, anomalies persist, often due to human psychology or structural factors in the market. By identifying these patterns, traders can capitalize on inefficiencies before they correct themselves.
Key stock market anomalies and how they work
Several anomalies are well-documented in financial literature and widely utilized by traders. Below are a few key ones:
-
Momentum effect
The momentum effect suggests that stocks which have performed well in the past tend to continue to perform well in the near future. This can be attributed to the behavioral bias known as “herding,” where investors tend to buy stocks that have already been successful, creating a self-fulfilling prophecy.Real-world example:
Between 2017 and 2018, Tesla (TSLA) exhibited the momentum effect. Despite negative sentiment around the company’s production delays, the stock price surged, driven by investor optimism and media coverage. Traders who identified the momentum pattern and entered the stock early were able to profit as the stock continued to climb.➡ Indicators to use:
- Relative Strength Index (RSI): Use the RSI to identify momentum strength. An RSI above 70 signals strong upward momentum, while below 30 suggests downward momentum.
- Moving Averages (MA): The 50-day and 200-day moving averages can help identify momentum trends. If the short-term MA crosses above the long-term MA, it’s often a signal of upward momentum (Golden Cross).
- Moving Average Convergence Divergence (MACD): This helps identify both the strength and direction of the momentum trend.
-
January effect
The January Effect is a seasonal anomaly where small-cap stocks tend to outperform larger stocks in the first month of the year. This is primarily due to tax-loss selling at the end of the previous year, where investors sell losing stocks for tax benefits, and then buy them back in January, boosting their prices.Real-world example:
Historically, small-cap stocks have shown higher returns in January compared to other months. For instance, in January 2018, the Russell 2000 index, which tracks small-cap stocks, surged by 11.8%. Traders who entered small-cap stocks in December, anticipating this seasonal anomaly, saw significant returns.➡ Indicators to use:
- Bollinger Bands: These are useful to identify periods of volatility and potential price breakouts in small-cap stocks as the January Effect often brings sudden price changes.
- Stochastic Oscillator: This is a momentum indicator that compares a stock’s closing price to its price range over a set period. It helps pinpoint buying and selling opportunities, especially during strong seasonal effects.
-
Earnings surprise effect
Stocks that report earnings above analyst expectations tend to continue rising, even after the earnings report is released. This is driven by the market’s delayed reaction to the news or a reassessment of the stock’s value.Real-world example:
When Apple (AAPL) reported Q1 2021 earnings that far exceeded expectations, its stock price jumped by over 6%. Traders who placed trades based on expected earnings surprises could have seen significant profits.➡ Indicators to use:
- Earnings Per Share (EPS): Tracking the EPS of a company helps determine whether an earnings surprise is likely.
- Volume Indicators: An increase in volume after earnings reports often signals the continuation of a price move. Look for volume spikes when earnings surpass expectations.
- MACD: Use MACD to confirm the continuation of the trend after an earnings surprise, particularly when the MACD line crosses above the signal line.
-
Value vs. growth anomaly
The value anomaly suggests that undervalued stocks (with low price-to-earnings (P/E) or price-to-book (P/B) ratios) outperform growth stocks over the long term. Contrarily, growth stocks often see rapid price increases in the short-term, but the long-term returns may not be as strong.Real-world example:
Companies like Johnson & Johnson (JNJ) and Procter & Gamble (PG) often fit the profile of value stocks. These companies have consistent earnings and low valuations relative to their earnings, and they have delivered strong, steady long-term returns, outperforming more volatile growth stocks like those in the tech sector.➡ Indicators to use:
- Price-to-Earnings Ratio (P/E): Look for stocks with a low P/E ratio, indicating they are undervalued relative to earnings potential.
- Price-to-Book Ratio (P/B): The P/B ratio is another indicator for identifying undervalued stocks.
- Dividend Yield: Value stocks often have consistent and higher dividend yields. Use this indicator to identify stocks with solid, sustainable cash flows.
Strategies to profit from stock market anomalies
To profit from stock market anomalies, traders can implement various strategies based on the anomaly they are targeting. Here are some of the most effective:
-
Momentum trading
Momentum traders buy stocks with strong recent performance and sell those with poor performance, capitalizing on continued price movement. This strategy is best used with technical indicators like the Relative Strength Index (RSI) or Moving Averages (MA) to confirm momentum.✅ Example:
A trader might use a strategy where they buy stocks with an RSI above 70 (indicating strong upward momentum) and sell those with an RSI below 30 (indicating weakness). -
Seasonal investing
Traders who use seasonal anomalies will time their investments to align with trends like the January Effect or the “Sell in May and Go Away” strategy (which suggests selling stocks in May and buying them back in October). They’ll enter positions in small-cap stocks in December, expecting an increase in January.✅ Example:
A trader may track the S&P 500 for patterns in past years and enter positions in small-cap ETFs (such as IWM) in late December, based on historical data showing outperformance in January. -
Earnings-driven trading
Earnings-driven trading involves anticipating earnings reports and making moves based on expected earnings surprises. Traders may enter positions before earnings reports, based on factors such as company history, analyst estimates, or insider activity.✅ Example:
If analysts expect an earnings beat from a tech company like Microsoft (MSFT), a trader might buy calls on MSFT options, expecting a post-earnings surge. -
Value investing
Value investing involves targeting stocks that are undervalued based on fundamental metrics, such as low P/E ratios, strong dividends, and solid growth potential. Investors who practice this strategy often look for companies with stable earnings that are trading at a discount.✅ Example:
Warren Buffett is known for using this strategy. For instance, he purchased shares of Coca-Cola (KO) in the late 1980s when the company was undervalued compared to its earnings potential. Over the following decades, the stock delivered significant returns.
