This paper studies efficient market hypothesis in prediction markets and the results are illustrated for the in-play football betting market using the quoted odds for the English Premier League. Our analysis is based on the martingale property, where the last quoted probability should be the...

Stock prices are well known to exhibit behaviors that are difficult to model mathematically. Individual stocks are observed to exhibit short term price reversals and long term momentum, while their industries only exhibit momentum. Here we show that individual stocks can be modeled by simple...

We discuss when and why custom multi-factor risk models are warranted and give source code for computing some risk … factors. Pension/mutual funds do not require customization but standardization. However, using standardized risk models in … quant trading with much shorter holding horizons is suboptimal: (1) longer horizon risk factors (value, growth, etc …

Evaluating risk measures, premiums, and capital allocation based on dependent multi-losses is a notoriously difficult … by a heavy-tailed background risk. A particular attention is given to the distortion and weighted risk measures and … allocations, as well as their special cases such as the conditional layer expectation, tail value at risk, and the truncated tail …

This paper proposes risk sharing strategies, which allow insurers to cooperate and diversify non-systemic risk. We deal … with both deviation measures and coherent risk measures and provide general mathematical methods applying to optimize them … all. Numerical examples are given in order to illustrate how efficiently the non-systemic risk can be diversified and how …
