New pre-built ratio, the Piotroski F-Score : PiotFScore

Dear All,

Under FUNDAMENTALS->ADVANCED you will now find a pre-built Piotroski F-Score called PiotFScore

Description

The Piotroski F-Score, ranging from 0 (worst) to 9 (best) is the sum of a company’s standing according to nine fundamental tests (each of which is scored 1 for pass and 0 for fail) identified by Joseph Piotroski as being useful in evaluating stocks that look cheap based on price-to-book. The approach starts with a presumption that such companies whose stocks are valued low are distressed and not likely to be adequately followed by analysts. Piotroski addresses the dearth of expert assessment through use of the nine tests, all of which can be readily calculated using basic financial data, to distinguish between firms that are genuinely distressed and those that are stronger.

For more information, please see the original research available on this link

NOTE: this factor is computed on-the-fly. Overusing it as in the ranking, rules, etc, will make your simulations slower.

Formula

These nine PASS/FAIL tests are added together resulting in a score from 0-9 (see image)

And here’s a very simple screen backtest using PiotFScore


Thanks!!!

Worked in one of my sims as a “Red Flag” filter. PiotFScore >= 2 in the buy rules (PiotFScore < 2 in the sell rules) improved my Sharpe Ratio significantly. Apparently, stocks with PiotFScore = 1 or 0 are a little volatile in this sim.

Nice!

This is great, Marco!!
