Stochastic dominance has been shown to be theoretically superior to mean variance (MV) analysis because it considers the entire return distribution and is based on minimally-restrictive assumptions regarding investor motives. This study uses stochastic dominance to examine whether adding internationally-based assets to a wholly-domestic portfolio generates diversification benefits. In contrast to previous MV findings, a New Zealand-only portfolio stochastically dominates four internationally-diversified portfolios across all periods considered. Similarly, the least internationally-diversified portfolio persistently dominates more diversified counterparts. Within-portfolio analysis supports the fundamental precept of finance theory showing that in the Asian Crisis period, the least risky/lowest return weighting schemes dominate those with a greater risk or higher return characteristic.

This book seeks to answer the essential question of the investment-worthiness of green instruments. It is evident that investing in green and energy-efficient firms will be the most profitable choice for wise investors in the years to come. The reconciliation of the social choice for green technology and investors’ choice for gray technology will be automatically achieved once green firms become more profitable than gray ones, in the Indian context. As there has been very little research done in this area, especially in the Indian context, this book addresses that gap. In order to do so, it follows the development of five different portfolios consisting of 100% green, 75% green-25% gray, 50% green-50% gray, 25% green-75% gray and 100% gray stocks, and attempts to answer questions such as: Do green portfolios entail less relative own-risk as compared to their gray counterparts? How effectively do green portfolios avoid market risk? Are green portfolios inherently more stable? Do green portfolios have a higher probability of surviving a financial crisis? Is the performance of green portfolios backed by their fundamentals? Is there any particular technical trading strategy that can ensure a consistently above-average return from these portfolios?
