The Financial API used by valinvest to get financial data has been rewritten and now requires a API Key in order to make request. So, the first step now is to register on https://financialmodelingprep.com/login and get an API key. Keep it, you will need it to use valinvest ;)
For a given stock ticker, valinvest calculates a score from 0 to 9. The higher the score, the better the company is according to the scoring methodology.
- Install it
pip install valinvest- Calculate score
>>> import valinvest
>>> aapl = valinvest.Fundamental('AAPL', YOUR_API_KEY)
>>> aapl.fscore()
6.8The aim of the package is to evaluate a stock according to his fundamentals by setting a score and identify buy and sells opportunies through technical indicators.
The scoring methodology is based on Joseph Piotroski's study (Value Investing: The Use of Historical Financial Statement Information to Separate Winners from Losers). The F-Score is used to help financial investment decisions by finding the best value stocks on the market.
The Piostroski score is calculated based on 9 criteria divided into 3 groups:
- Return on Assets (1 point if it is positive in the current year, 0 otherwise)
- Operating Cash Flow (1 point if it is positive in the current year, 0 otherwise)
- Change in Return of Assets (ROA) (1 point if ROA is higher in the current year compared to the previous one, 0 otherwise)
- Accruals (1 point if Operating Cash Flow/Total Assets is higher than ROA in the current year, 0 otherwise)
- Change in Leverage (long-term) ratio (1 point if the ratio is lower this year compared to the previous one, 0 otherwise)
- Change in Current ratio (1 point if it is higher in the current year compared to the previous one, 0 otherwise)
- Change in the number of shares (1 point if no new shares were issued during the last year)
- Change in Gross Margin (1 point if it is higher in the current year compared to the previous one, 0 otherwise)
- Change in Asset Turnover ratio (1 point if it is higher in the current year compared to the previous one, 0 otherwise)
This software calculates an alternate version of the F-Score as follows:
- Net Revenue
- EBITDA
- Earnings per share (EPS)
- CROIC
- ROIC
- EBITDA cover ratio
- Debt coverage
- Beta
- Equity buyback
