contrarian and momentum investing strategies are two techniques which are used in stock markets to enhance portfolio return. contrarian investing strategy states that stocks which had better performances in the past should be sold and stocks that had poor performances should be bought. in practice, this strategy is used for a package of stocks and for portfolio formation. the main objective of ...

We study the 52-week high momentum strategy in international stock markets proposed by George and Hwang [George, T., Hwang, C.Y., 2004. The 52-week high and momentum investing. Journal of Finance 59, 2145–2176.]. This strategy produces profits in 18 of the 20 markets studied, and the profits are significant in 10 markets. The 52-week high momentum profits exist independently from the Jegadeesh ...

First examples of quasi-exactly solvable models describing spin-orbital interaction are constructed. In contrast with other examples of matrix quasi-exactly solvable models discussed in the literature up to now, our models admit infinite (but still incomplete) sets of exact (algebraic) solutions. The hamiltonians of these models are hermitian operators of the form H = −∆ +V1(r)+ (s · l)V2(r)+ (...

We examine the implications of shortand long-run consumption growth fluctuations on the momentum and contrarian profits and the value premium in a unified economic framework. By allowing time-varying firm cash flow exposures to the short-run and long-run shocks in consumption growth, we find the otherwise standard intertemporal asset pricing model goes a long way in generating the momentum and ...

Researchers have identified hundreds of factors that purport to predict equity returns; we find a half dozen that provide an opportunity to outperform the market. To maximize risk-adjusted returns, diversify across smart beta strategies that access the value, low beta, profitability, investment, momentum, and size factors. Systematic rebalancing to fixed weights—reducing exposure to popular fac...

Service-oriented architecture (SOA) is gaining momentum as an emerging distributed system architecture for business-to-business collaborations. This momentum can be observed in both industry and academic research. SOA presents new challenges and opportunities for testing and verification, leading to an upsurge in research. This paper surveys the previous work undertaken on testing and verificat...
