Many finance models assume the existence of noise traders who push asset prices away from fundamental values. Yet empirically, these "animal spirits" are challenging to observe because fundamental values are inherently unobservable. We examine a novel database of trades by ETF authorized participants who specifically trade to correct violations of the law of one price. These trades allow us to measure arbitrage activity. We show that noise traders do not cancel each other out and arbitrage activity is associated with predictable price distortions. Our analysis indicates that noise traders exert a non-fundamental impact on market outcomes even when arbitrageurs are active. Thus, noise traders are not simply noise, they impact prices.
