Market timing

For many investors, passive investing can be a no-brainer and is suggested by many, especially those who think that the walk is random. However, it does not mean that the passive investors do not trade – the ETFs trade instead of them. The indexes that are being tracked are rebalanced to account for changes in the market cap, mergers, delistings, or IPOs. The novel research shows that it matters how the ETFs trade. Even though the differences are not that big, for a long-term horizon, the differences compound. For active traders, the paper shows that the rebalancing of the ETFs could be utilized by trading in advance.

Since recessions and bear markets come hand in hand for several asset classes, recession predictions have always been the foremost concern. The yield curve slope, defined as the difference between long and short-term rates, is the leading indicator backed by numerous research papers. Hansen (2021) builds on this theorem, but the author improves the recession prediction by his empirical observation that the VIX index (index of implied equity volatility or fear index) and the slope co-move in counterclockwise cycles, which align with business cycles.

The high-frequency data in cryptocurrency markets is available at any time of the day, which facilitates the studies of periodicity measures beyond what’s possible in other markets. The research paper by Hansen, Kim, and Kimbrough (2021) investigates the periodicity in volatility and liquidity in two major cryptocurrencies, Bitcoin and Ether, using data from three exchanges, Binance, Coinbase Pro, and Uniswap V2. In particular, the authors measure relative volatility and relative volume across days, hours, and minutes. Their results have confirmed the presence of recurrent patterns in volatility and volume in studied cryptocurrencies for the periods day-of-the-week, hour-of-the-day, and within the hour.
