Abstract :Fama\'s \"proxy\" hypothesis and Liquidity Preference Theory suggest that there is an inverse relationship between interest and inflation rates and stock prices/returns. On the other hand, according to the Fisher hypothesis suggests that there is a positive interaction between the stock market returns and inflation rate. The increase in the interest rate, on the one hand, due to the increase in the discount rate and, on the other hand, due to the alternative cost of investment, reduces the interest towards the stock market and increases the tendency towards the bond market, causing share prices to fall. However, it is seen that the relationships in question are far from certain, and the findings obtained from different samples with different methods give results that do not match the expectations implied by the hypotheses. The nexus between the stock market and interest and inflation rates in Türkiye, which has been faced with high interest rates and inflation for many years except short-term periods, has been examined using different time series methods in the empirical literature. In this study, the subject is investigated in a different way through the Quantile Regression (QR) method. In the study, where the effect of the nominal interest rate on stock prices was examined by dividing it into two components: real interest and inflation rates, a four-fold sub-sector distinction was made, namely service, financial, industrial and technology indices. When it comes to the effect of nominal and real interest rates on returns in QR estimates, it is seen that the service and industrial sectors differ in terms of both tail and sign. The similarities between Least Squares estimates and QR estimates are striking. However, the potential of the volatility level of variables to create differentiation in relationships is also a point that should not be overlooked.
