We estimate the profitability of global index-level trading strategies formed on daily weather conditions across 49 countries. We use pre-market weather conditions (sunshine, wind, rain, snow, and temperature) and the statistical relationship between weather and returns to predict index returns...

I show that the growth of high-frequency trading, due to its heavy reliance on computer algorithms, can be associated with a reduction of human errors and financial anomalies in the market. Trades in which a non-high-frequency trader is the liquidity demander exhibit abnormally high buy (sell)...

We study crowded markets using a symmetric model of trading among strategic informed traders. Traders may have incorrect beliefs about markets' crowdedness; this distorts traders' strategies and market prices. When traders overestimate the crowdedness, they believe markets to be less liquid and...

Feedback trading strategies have gained much popularity among researchers in the last decadesand are used to illustrate how new information based on returns is reflected in the markets. This paper extends previous studies by decomposing the overall return premium and introducing the global...

In what follows we present systematic trading and discuss the benefits. We evaluate contemporary trends, the opportunities arising from machine learning and the operational cost challenges faced, leveraging on the history of the industry to demonstrate why maintaining a competitive edge is...

The overwhelming empirical support of the Efficient Market Hypothesis makes it one of the widely accepted understandings in modern economics. The internal contradiction, relating to the fact that if inefficiencies didn't exist, opportunists would not search for them, which would in turn give...

The momentum effect is a systematic inefficiency in the market that can be exploited by a trading strategy. This conclusion is supported by theoretical and empirical evidence. But the academic research that tries to quantify the performance of this kind of strategy often relies on a methodology...

We present the "Tax Day Trade," a one day trade that gains an average of 1/2%. The trade was developed using the "Strategic Analysis of Markets Method (SAMM)" described in the two volume series "The Strategic Analysis of Financial Markets" (forthcoming from World Scientific). Detective work...

Technical Analysis (TA) is a security analysis methodology based on the study of past market data. Although it has been criticized by academics and the profitability of many related strategies has been statistically rejected, TA remains highly popular among practitioners and retail investors, in...

I use industry-level returns in foreign markets to examine the hypothesis that value-relevant foreign information slowly diffuses into the stock prices of U.S. multinational firms. A trading strategy that exploits foreign information generates abnormal returns of 0.8% monthly. I find that the...
