Ohlson o-score: Explained
BY TIO Staff
|August 12, 2024The Ohlson O-Score is a credit scoring system that is used to predict the likelihood of a company going bankrupt within the next two years. Developed by James Ohlson in 1980, this score has been widely adopted in the financial industry due to its accuracy and reliability. It is based on a multivariate, non-linear model that takes into account several financial ratios and market data.
For traders, understanding the Ohlson O-Score can provide valuable insights into the financial health of a company and its potential for future success or failure. This can inform investment decisions and risk management strategies, making it a crucial tool in the trader's toolkit.
Understanding the Ohlson O-Score
The Ohlson O-Score is calculated using nine different financial variables, each of which contributes to the overall score. These variables include factors such as the company's size, its financial leverage, its liquidity, the recent performance of its stock, and the market's valuation of the company. Each of these variables is weighted according to its importance in predicting bankruptcy.
The score ranges from 0 to 1, with higher scores indicating a greater likelihood of bankruptcy. A score of 0.5 or above is generally considered to be a warning sign that the company is at risk of bankruptcy.
Variables Used in the Ohlson O-Score
The nine variables used in the Ohlson O-Score are as follows: size, financial leverage, working capital/total assets, current liabilities/total assets, one if total liabilities exceed total assets, net income/total assets, funds from operations/total liabilities, one if a net loss, and stock return. Each of these variables is given a specific weight in the calculation of the score.
It's important to note that the weights assigned to each variable are based on statistical analysis and are designed to maximize the predictive power of the score. As such, they may not necessarily reflect the relative importance of each variable in a broader financial context.
Interpreting the Ohlson O-Score
The Ohlson O-Score is a probabilistic measure, meaning that it provides an estimate of the likelihood of bankruptcy, not a definitive prediction. As such, it should be used in conjunction with other financial indicators and market data when making investment decisions.
A high Ohlson O-Score does not necessarily mean that bankruptcy is imminent. Rather, it indicates that the company is exhibiting financial characteristics that are commonly associated with companies that have gone bankrupt in the past. Similarly, a low score does not guarantee that the company is financially secure, but rather suggests that it is not currently exhibiting these risk factors.
The Importance of the Ohlson O-Score in Trading
The Ohlson O-Score is a valuable tool for traders because it provides a quantitative measure of a company's financial risk. This can help traders to assess the potential downside of an investment and to manage their exposure accordingly.
For example, a trader might choose to avoid companies with high Ohlson O-Scores, or to hedge their investments in these companies with options or other derivatives. Alternatively, a trader might see a high Ohlson O-Score as an opportunity to short the company's stock, betting that its price will fall.
Using the Ohlson O-Score in Fundamental Analysis
The Ohlson O-Score is particularly useful in the context of fundamental analysis, which involves evaluating a company's intrinsic value by examining its financial statements and market position. By providing a quantitative measure of financial risk, the Ohlson O-Score can complement other fundamental indicators, such as earnings per share (EPS), price-to-earnings (P/E) ratio, and dividend yield.
In addition, the Ohlson O-Score can help to identify companies that are undervalued by the market. If a company has a low Ohlson O-Score but its stock is trading at a low price, this could suggest that the market is overestimating the company's risk of bankruptcy, potentially creating an opportunity for profit.
Using the Ohlson O-Score in Technical Analysis
While the Ohlson O-Score is primarily a tool for fundamental analysis, it can also be used in conjunction with technical analysis. Technical analysts, who base their trading decisions on patterns in price data and other market indicators, can use the Ohlson O-Score to add a layer of financial context to their analysis.
For example, if a technical analyst identifies a bearish trend in a company's stock but the company has a low Ohlson O-Score, this could suggest that the trend is likely to reverse. Conversely, if a company has a high Ohlson O-Score and its stock is in a bullish trend, this could be a warning sign that the trend is about to end.
Limitations of the Ohlson O-Score
While the Ohlson O-Score is a powerful tool, it is not without its limitations. One of the main criticisms of the score is that it is based on historical data and may not accurately predict future bankruptcies. This is particularly true in times of economic turmoil, when the financial characteristics of bankrupt companies can change rapidly.
Another limitation of the Ohlson O-Score is that it does not take into account the company's industry or market conditions. A company in a struggling industry or a bear market may have a high Ohlson O-Score even if it is fundamentally sound.
Accuracy of the Ohlson O-Score
The accuracy of the Ohlson O-Score is a subject of ongoing debate. While some studies have found that the score is a reliable predictor of bankruptcy, others have questioned its predictive power. In general, the Ohlson O-Score is considered to be more accurate than other bankruptcy prediction models, but less accurate than more sophisticated financial models.
It's important to remember that the Ohlson O-Score is a probabilistic measure and should not be used as the sole basis for investment decisions. Instead, it should be used in conjunction with other financial indicators and market data.
Applicability of the Ohlson O-Score
The Ohlson O-Score was developed based on data from publicly traded companies in the United States, and its applicability to other markets is not guaranteed. In particular, the score may not be accurate for companies in emerging markets, where financial reporting standards and bankruptcy laws can be very different.
Furthermore, the Ohlson O-Score may not be applicable to all types of companies. For example, it may not be accurate for financial institutions, which have unique financial characteristics and regulatory requirements. Similarly, it may not be accurate for startups and other companies with limited operating history.
Conclusion
The Ohlson O-Score is a valuable tool for traders, providing a quantitative measure of a company's financial risk. By taking into account a range of financial variables, it can help traders to assess the potential downside of an investment and to manage their exposure accordingly.
However, like all financial tools, the Ohlson O-Score has its limitations. It should be used in conjunction with other financial indicators and market data, and its predictions should be interpreted with caution. Despite these limitations, the Ohlson O-Score remains a cornerstone of financial analysis and an essential part of the trader's toolkit.
