The Relationship Between Earnings-to-Price, Current Ratio, Profit Margin and Return: An Empirical Analysis on Istanbul Stock Exchange
Bibliographic record
Abstract
This paper aims to investigate the relationship between current ratio, earnings to price, net profit margin and stock returns in İstanbul Stock Exchange over the period 2008-2016 by employing panel data analysis. Due to the existence of heteroskedasticity, cross sectional dependence and autocorrelation in sample data, two-way fixed effects model is estimated by robust estimators. Both Parks-Kmenta and Beck-Katz methods are conducted to check whether the results are consistent or not. According to Park-Kmenta estimation model, the results show that earnings to price and net profit margin are significant to explain stock returns in İstanbul Stock Exchange while current ratio is found insignificant. Moreover, the test based on Beck-Katz model produces the similar results. Earnings to price and net profit margin are strong determinants of stock returns in Istanbul Stock Exchange. Stocks with higher E/P ratios and profit margins generate higher returns for the next period.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
