Price and volume dynamics in second-hand dry bulk and tanker shipping markets

The relationship between trading volume, prices and return volatility is thoroughly investigated in different second-hand dry bulk and tanker market segments. The objective is to gain fruitful insight on the sale and purchase market dynamics, and the sensitivity of vessel price movements following the arrival of new information signals in the shipping markets. Contemporaneous relationships are identified between returns and volume, particularly in the markets of handysize and panamax bulks as well as of handysize and aframax tankers. Price changes are found to have an impact on trading volume indicating that expectations to higher capital gains induce increases in trading activity. Volume appears to have a negative impact on the volatility of price changes mainly in the dry bulk market; this may be due to thin trading, limited transaction transparency and absence of vessel price quotes. The empirical findings can contribute to a better understanding of shipping markets' microstructure and price volatility dynamics by market participants. This, in turn, can be useful for investors who construct their portfolios of real assets with a view to attain superior capital gains, controlling for the underlying investment risk.
