WebThis paper presents a new perspective on the Fisher hypothesis in relation to the real stock returns and expected inflation, by using the monthly real stock returns for the S&P 500 and inflation rates in US from January 1990 to December 2016. Results suggest a strong evidence of regime-dependence of stock market return for a two-regime MS-FITGARCH … WebAlmasi et al. (2024) used MS–FITGARCH to model the long-term memory and analyze oil shocks in the Tehran Stock Exchange through monthly data belonging to the 1998–2024 period. Their research results indicated that MS–FITGARCH showed the significant, positive effects of oil price shocks
