Market anomalies are common and are regularly reported in the media. For example, Marine Link recently reported how 'second-hand VLGC values have not come down as sharply as the freight market and are trading at a high multiple to vessel earnings'.
What you need to know about a market anomaly.
Since future stock prices follow a random walk pattern and are generally unpredictable, anomalies can appear, disappear and come back again without any warning. Anomalies can take many different forms including a smaller company outperforming a larger company, stocks becoming neglected and stocks with below-average price-to-book ratios outperforming the market. Another well-known anomaly is the January Effect, which relies on the idea that stocks that underperformed in the fourth quarter of the previous year tend to outperform the markets in January.
