In this study, we explore the regime-dependent impact of three investor sentiment proxies on the Non-Fungible Tokens (NFTs) market. To that end, first, we create an NFT crypto index and assign the following variables to represent investor sentiment: Google Trend (GT), Fear and Greed (FG) Index, and Volatility Index (VIX). The empirical examination is conducted through Markov switching vector autoregression analysis and causality tests on obtained regimes. According to the results, regimes one and two in each model are detected as bull and bear markets, respectively. The LR test conducted through restricted autoregressive coefficients of the MS-VAR model indicate that GT Granger cause NFTs index in the bear market regime, whereas FG and VIX variables are significant in bull markets. Accordingly, it is concluded that as a proxy of public insight, GT becomes significant in the downward trend of NFTs. This finding can be attributed to the public interest that typically emerges subsequent to the peak of market bull runs. However, as an indicator of investor fear, FG and VIX indexes can be considered early-warning signals of trend reversals in bull markets.
