Ever thought of using a fundamental stop-loss?
Do you hate a price driven stop-loss system?
If you do you are most likely a hard core value investor, but here is a great alternative suggested by a friend and long-term subscriber to the screener.
It will help you limit your losses when the underlying business starts to go downhill.
And best of all it needs little or no research.
Inspired by Warren Buffett
My friend said he got the idea from an article where Warren Buffett mentioned that he did not care what had happened to a company’s share price as long as operationally the company was still doing well.
Warren mentioned that he got this idea from Philip Fisher that only sold investments for operational reasons.
Quantitative fundamental stop loss
So how can you easily find out if a company’s operations are deteriorating without doing a lot of research?
My friend does this by selling an investment if the company’s Piotroski F-Score falls below 5, replacing it with one of the best ideas from his favourite screen.
Piotroski F-Score summarised
The Piotroski F-Score is calculated with the use of the following 9 ratios:
1. Return on assets (ROA)
2. Cash flow return on assets (CFROA)
3. Change in return on assets
4. Quality of earnings (accrual)
5. Change in gearing or leverage
6. Change in working capital (liquidity)
7. Change in shares in issue
8. Change in gross margin
9. Change in asset turnover
How the Piotroski F-Score is evaluated
Best or high Piotroski F-Score = 8 or 9
Worse or low Piotroski F-Score = 0 or 1
So you can see, from all the ratios above, the F-Score is an excellent way you can measure the fundamental health of your investments.

How you can find the Piotroski F-Score
In the screener the Piotroski F-Score is updated every time a company posts results, including quarterly and half year results. This makes it really easy for you to get an up to date Piotroski F-Score value of all the companies in your portfolio.
You simply call up the name of the company and you can immediately see the F-Score of the company.
