Show Abstract
This study aimed to identify the impact of liquidity risk in expected excess returns of Brazilian corporate bonds in
the secondary market. We performed a battery of regression analysis with semiannual unbalanced panel data of 101
securities over eight semesters (first semester 2006 to the second half of 2009), totaling 382 observations. Seven
proxies (bid/ask spread, %zeroreturns, age, amount outstanding, face value, number of bonds and %time) were used
to test the impact of liquidity risk in the yield spreads. Ten other variables (Slope Factor, Credit Risk Factor, risk-free
rate, rating, duration, four accounting variables and equity volatility) were used as other yield spread determinants.
The null hypothesis that there isn´t a liquidity premium for bonds in Brazilian secondary market was rejected for
only three proxies (bid/ask spread, face value and number of bonds).
The premmia founded are quite small (1.9 basis point for each 100 basis
points increase in the bid/ask spread, 0.5 basis point to 1% face value
increase and 0.17 basis
point for each less 1000 bonds issued) Anyway there was loss of efficiency of liquidity proxies following correction
for autocorrelations and potential endogeneity, either through the inclusion of fixed effects, first differences analysis
or simultaneous equation analysis. These results point to the fact that maybe liquidity risks are not important to the
Brazilian corporate bonds secondary market expectations.
