To this aim, this study applies novel quantile-based approaches, namely Quantile autoregression unit root test, Quantile-on-quantile approach, and Quantile Granger-causality test covering the period from 01 January 2020 to 15 September 2020. Main findings of the study are (1) G7 stock return series are stationary for all quantiles of the conditional distributions with minor exceptions meaning that shocks have temporary effects on stock returns of G7 markets. (2) The impact of Twitter-based uncertainty strongly depends on the market condition, whether it is bullish or bearish for all G7 markets. A heterogeneous association exists between variables caused by different market conditions. (3) A bi-directional causal association exists between stock returns-TEU and stock returns-TMU. This result confirms the existence of feedback hypothesis between G7 stock returns and TEU, TMU, respectively. This study provides important policy implications and recommendations for policy makers and investors on the nexus between Twitter-based uncertainties and stock returns.</p>","PeriodicalId":47461,"journal":{"name":"International Journal of Finance & Economics","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131868640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings indicate that while the conventional unit root tests support the persistence of shocks to interest rates and inflation, the quantile unit root test demonstrates an asymmetric behaviour of the persistence, implying a time-varying structure with mean reversion (persistency) of the shocks in low (high) inflation periods. Furthermore, the half-lives increase with the positive shocks, indicating a longer speed of adjustment in the high inflation regime.

Our dataset consists of daily prices spanning from January 2017 through to October 2022, encapsulating pre- and post-epidemic eras. Generally, our findings suggest that Tether presents the least overall volatility throughout the time-frequency spectrum. USD Coin demonstrates ephemeral turbulence, contrary to Tether's maturity in influencing market equilibrium through token issuance and trade responses. In the post-epidemic sample, both stablecoins indicate mean reversion, with USD Coin showing marginally better efficiency. Conversely, investment tokens display persistent clusters due to retail traders and long-term fundamental institutions. Although both tokens illustrate multifractal volatility, Ethereum unveils more essence of self-similarity than Bitcoin. Hence, there is no evidence that Ethereum truly duplicates Bitcoin since policy-related events differ between them, as both return series move incongruously. Conditional dynamics signify that all cryptocurrencies, except Tether, were affected by the pandemic transition of COVID-19 and subsequent macroeconomic news. The unconditional volatility of stablecoins evinces zero-mean errors, antithetical to investment tokens exhibiting annual cycles. The fractal geometry suggests that investment tokens simulate one-dimensional lines, whereas stablecoins mimic two-dimensional planes.</p>","PeriodicalId":47461,"journal":{"name":"International Journal of Finance & Economics","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121672027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
