RT Journal Article T1 Green bond market and sentiment: is there a switching behaviour? A1 Piñeiro Chousa, Juan Ramón A1 López Cabarcos, María Ángeles A1 Sevic, Aleksandar K1 Green bonds K1 Panel smooth transition regression K1 MSCI World Index K1 Sentiment AB We examine the impact of Twitter sentiment on the returns of four selected bond indices via the selection of relevant threshold variables, such as the S&P 500 Index, the VIX, and the MSCI World Index. If overreaction or underreaction to significant changes in the market occur regularly (De Bondt and Thaler, 1985, 1987; Jegadeesh and Titman, 1993), it is assumed that Twitter users respond with different intensities in the case of rising, falling or rather indeterminable markets. We fail to find evidence that the S&P 500 Index and VIX are relevant in supporting the switching behaviour. However, the MSCI World Index, to a certain extent, causes this relationship to diverge from the linear one. These claims become stronger when lagged and cubic sentiment variables have been included in the panel smooth transition regression (PSTR) PB Elsevier YR 2022 FD 2022 LK http://hdl.handle.net/10347/27725 UL http://hdl.handle.net/10347/27725 LA eng NO Journal of Business Research 141 (2022) 520-527. https://doi.org/10.1016/j.jbusres.2021.11.048 DS Minerva RD 24 abr 2026
