The share of the First Growths' trade on Liv-ex seems to act as a proxy for market sentiment. When buyers and sellers are feeling optimistic, First Growths see an increased level of trade. Lately, the level has fallen to around 35%. As the dotted line on the chart shows, this is close to the pre-bull market level of 2004.
