However, companies with lower profitability (first quartile) are not the ones with the
highest value for the variable SIZE, nor are those more indebted.
In what pertains to the control variables SGROW, CAR and CLR, these results
confirm the positive correlation indicated in the correlation matrix, since it is in the
higher profitability group that is found the maximum value for this indicator.
The results obtained when carrying out the univariate analysis for two most
representative sectors are very similar to those obtained for the whole sample.
The results for the estimation on the equations from Section 2.3 are presented in
Table V.
The inverse relationship of the INV, AP, AR and CCC variables with the dependent
variable ROA, confirms the results obtained from the correlation matrix. Although
providing additional credit to the final consumer and possessing a larger inventory is
bound to potentiate an increase in sales, these results seem to imply that the
outperformance results are in favor of maintaining both a low number of days of
inventory and number of days accounts receivable.
However, this inverse relationship may stem from the influence of the dependent
variable over the independent variables and these results be affected by endogeneity
problems. In that way, the negative relationship with profitability can be attributed to
