In this paper we develop a concrete and fully implementable approach to the optimization of functionally generated portfolios in stochastic portfolio theory. The main idea is optimize over family rank-based parameterized by an exponentially concave function on unit interval. This choice can be motivated long term stability capital distribution observed large equity markets allows us circumvent ...

Modern Universities play increasingly important role in contemporary society, advancing frontiers of science and transforming regional economies. As funding models modern universities change, they adopt some features a business organization. While their ability to attract becomes vitally for universities, especially from private sources (industry), balance between fundamental applied research v...

The paper presents smallholder farmers' perceptions on attributes of bread wheat varietiesbased on primary data collected from 524 households in four major wheat growing areas ofEthiopia. The results indicated high value of attainment indices for improved varieties comparedto landraces, which shows how the demanded attributes are embodied more in improved ones.Grain yield and yellow and stem ru...

The Modern Portfolio Theory of Markowitz maximized portfolio expected return subject to holding total portfolio variance below a selected level. Digital Portfolio Theory is an extension of Modern Portfolio Theory, with the added dimension of memory. Digital Portfolio Theory decomposes the portfolio variance into independent components using the signal processing decomposition of variance. The r...

Portfolio optimization requires the minimal risk with certain expected return. The risk structure of securities, such as their exposure to countries, industrial sectors, or commodity/factor, have to be characterized, and then the optimal weights of securities in a portfolio can be determined to minimize the exposure of the portfolio to any specific risk factor. Typically, the risk factors are n...

Sowing time, as an element, is important to improving the adaptation of cultivars environmental conditions and achieving high seed yields. The field experiment was conducted from 2018–2019 at Experimental Station Vytautas Magnus University Agriculture Academy. experimental design included treatments with different sowing dates: eight dates in 2018 10 2019. first spring rapeseed carried out when...

The paper compares three portfolio optimization models. Modern portfolio theory (MPT) is a short-horizon volatility model. The relevant time horizon is the sampling interval. MPT is myopic and implies that investors are not concerned with long-term variance or mean-reversion. Intertemporal portfolio choice is a multiple period model that revises portfolios continuously in response to relevant s...
