This co-movement of the time series has been documented in studies using various frameworks and settings. Similar to VPIN results around the flash crash, the authors find support for the predictive capability of market microstructure and document the largest drop in the average PIN in more than a decade during the first quarter of , just before the dot-com bubble burst.

These microstructure patterns preceding market crashes are not surprising considering the following chain of events: In periods of elevated enthusiasm for stocks, households provide higher inflows. As a consequence, market-making specialists start to increase the gap between bid and ask prices to cover expected losses against informed traders. The spreads keep increasing to the point that liquidity dries up, demand and supply move out of balance and a market correction occurs.

Then the cycle begins again. In recent decades, a change has occurred that may be even more important than lowered obstacles or reduced frictions to market access. As a consequence of lower trading costs, financial markets have seen a significant decline in risk premiums. According to Jones, the equity premium fell in the first half of the 20th century; this was in line with the decreasing average share turnover and flat or rising commissions.

Aggregate returns are not the only statistics reflecting changes in trading conditions. The authors analyze the temporal change of abnormal profits made on 11 well-known anomaly strategies — portfolios that provide excess returns without betting on known risk factors — and find that anomaly profits, although still significant, have declined in previous decades. More important, they argue that decreasing market frictions help explain this pattern. In addition, the literature on this topic has provided further evidence of shrinking anomaly profits and thus increasing market efficiency in U.

They show that for the overwhelming majority of countries, time-series predictability of returns has decreased significantly and converged toward random noise. All these findings suggest why such anomalies can exist in the first place. However, these patterns are not tradable in themselves because of transaction costs, flaws in information acquisition or other kinds of friction. Market microstructure theory positing a positive relationship between uninformed trading and liquidity has been supported by evidence over the previous century and in recent decades.

Additional information

In the meantime, anomaly profits have declined as arbitrage barriers have gradually been reduced, thus making capital markets more efficient. The money inflows from households became a primary factor in trading profits due to the shrinking magnitude of those arbitrage barriers. The effect this rising household stake will have on financial markets remains obscure for now. Either we will see a sharp drop in household inflows along with declining equity prices or the market will adapt to a new regime with elevated retail participation and low trading costs.

Whichever happens, one thing is sure: Competition among investors is not going to decrease, and hence they will have to fight for their profits harder than ever, making the markets even more efficient. Daniel O. Cajueiro and Benjamin M. Joseph G.
