This paper points out to loopholes in Modern Portfolio Theory (MPT) and fundamental flaws that question its validity and applicability not only for investment but for education as well. Using theoretical analysis, Monte Carlo simulations and market data I present and discuss theoretical, as well...

Marketing is attributed to be the dominant factor for the failure of the successful commercialization of a new product development. However, its funding aspects and the relation with engineering-related efforts such as the technical development and manufacturing is less studied. This report...

The distribution function of a weighted sum of weakly correlated non-identical lognormal random variables is required in various fields of science and engineering and specifically in finance for portfolio management as well as exotic options valuation. Unfortunately, it has no known closed form...
