The Indian stock markets have been experiencing a bloodbath for the past several weeks. While investors have lost over 9 lakh crores in this market slide, the cardinal truth is that stock markets will always go up in the long run! Therefore, rather than seeing this as a disaster, investors should take this as an opportunity to fill their portfolios with quality stocks. So what if there was a clear formula to pick fundamentally strong stocks? The answer lies in the Piotroski Score! Check out this blog to know the meaning of this term and how it can help in stock selection. 

What is the Piotroski Score?

What is the Piotroski Score

The Piotroski Score is a stock evaluation and selection tool used by investors to check a company's financial strength before investing. It was created by Joseph Piotroski, an accounting professor at the University of Chicago, in the year 2000. The score helps investors find fundamentally strong companies by analysing various financial factors related to crucial parameters like the company’s profitability, debt levels, liquidity, and operating efficiency. Each factor is assigned a score of 0-1, making the total Piotroski Score for a company ranging between 0-9. This method is especially useful for value investors who look for undervalued stocks with strong fundamentals. 

How to Calculate the Piotroski Score?

The total Piotroski Score is calculated by evaluating a company based on 9 financial factors under three broad parameters.

How to Calculate

Significance

Profitability

Net Income 

Positive Net Income in the current year

To ascertain the ability of the company to generate profits

Return of Assets (ROA)

ROA = Net Income / Total Assets

Ability of the company to utilise assets efficiently

Operating Cash Flow

Positive Cash Flow from Operations

Checking Operating Cash Flow from Cash Flow Statement 

Ability of company to generate profits from its operating activities. 

Accruals

OCF > Net Income

Compare OCF and Net Income

If OCF is higher than Net Income, profits are backed by cash flow, reducing the risk of accounting manipulations.

Leverage and Liquidity

Change in Leverage 

Lower debt-to-assets ratio than last year

Compare current & previous Debt/Assets ratio

Decreasing leverage shows reduced financial risk and dependency on debt.

Current Ratio

Higher current ratio than last year

Compare current & previous Current Ratio (Current Assets/Current Liabilities)

A higher current ratio indicates improved liquidity and short-term financial health.

Change in the number of Outstanding Shares

No Issue of  New Shares 

Compare current & previous total shares outstanding

If no new shares are issued, it prevents dilution of existing shareholders' value.

Operating Efficiency

Gross Margin

Higher Gross Margin than Last Year

Compare current & previous Gross Margin

A rising gross margin suggests better cost control and profitability.

Asset Turnover Ratio

Higher Asset Turnover than Last Year

Compare current & previous Asset Turnover

Measures how efficiently the company is using assets to generate revenue.

 

Interpretation of the Piotroski Score

The Piotroski Score allocates a score of 0 or 1 to various factors of fundamental analysis to eventually get the total Piotroski Score for a company. A company with a higher score indicates a financially stable and potentially profitable investment opportunity, while a company with a lower score is considered to be a high-risk investment option. 

The interpretation of the Piotroski Score is given below.

Strong Companies (Score 7 to 9) - Good Investment Potential

Strong Companies (Score 7 to 9) - Good Investment Potential

A company with a Piotroski Score between 7 and 9 shows that the business is financially strong. It highlights that the company is generating profits, managing its debt well, improving efficiency, and has strong cash flow. These companies are less likely to face financial distress and often have stable or growing business operations. Companies in this range could be good long-term investment options, especially when they are available at reasonable valuations. However, investors should still check other factors like market trends, management quality, and industry conditions before investing.

Average Companies (Score 4 to 6) - Needs Further Analysis

Average Companies (Score 4 to 6) - Needs Further Analysis

A company with a Piotroski Score between 4 and 6 falls in the middle range. This means the company has some strong financial aspects but also some weaknesses. It could be a growing company that has not yet fully stabilised or a mature company facing challenges in profitability, efficiency, or debt management. Thus, stocks in this range should be analysed further before making investment decisions to check if the company’s weak areas are temporary or signs of deeper problems. If the company's fundamentals are improving, it may still be a good investment opportunity. However, if financial health is deteriorating, it could pose to be a risky investment.

Weak Companies (Score 0 to 3) - High-Risk Investment

Weak Companies (Score 0 to 3) - High-Risk Investment

A Piotroski Score between 0 and 3 is a red flag. It means the company is struggling with low profitability, increasing debt, poor cash flow, or inefficient operations. These companies are at a higher risk of financial trouble, which can lead to falling stock prices, loss of investor confidence, and in extreme cases, bankruptcy.  Investors should be cautious when considering stocks in this category, especially for long-term investments. These companies may be value traps where the stock price looks cheap but continues to decline due to weak financials. Unless there is a strong turnaround plan or external factors improving the company’s prospects, it is generally safer to avoid such stocks.

What are the Pros and Cons of using the Piotroski Score?

The Piotroski Score is an efficient way to find hidden gems from the abundance of stocks in the stock markets. However, before using this tool, it is also important to know the pros and cons of using it to make informed investment decisions.
