Abstract

Purpose

The effect of the cost of capital CEC on the investing and financing decisions is a matter of considerable interest and importance to the financial studies. However, the impact of CEC on the stock prices is not well established. This research aims to examine whether the CEC has a significant incremental explanation of the changes in the stock prices which the basic traditional accounting variables could not provide.

Design/methodology/approach

Applies the adjusted constant dividend‐growth model to measure the CEC and the incremental explanatory power test on a sample of 37 companies listed on NYSE.

Findings

The results indicate that there is non‐significant impact of CEC for the full sample, the small size firms, and the manufacturing firms. However, I find an evidence that CEC has a significant impact on the stock prices for both the large‐size firms and the non‐manufacturing firms.

Research limitations/implications

The study was completed at a specific date of measurement which puts some limitations on the generality of its results.

Originality/value

Assesses whether the cost of equity possess incremental explanation to the change in the stock prices beyond the explanation provided by the traditional accounting variables.
