Portfolio Diversification Between Developed And Less Developed Economies

This study
examines the hedging effectiveness of portfolio investment diversification
between developed and developing economies; with focus on the Nigerian stock
asset vis–vis the stock assets of the United States (US) and United Kingdom
(UK). Its main contribution is in the analysis of optimal portfolio
diversification using optimal portfolio weight (OPW) and optimal hedging ratio
(OHR). Empirical findings show that the OPW and OHR are low, which indicates impressive
potential gains from combining Nigerian stock assets in an investment portfolio
with US and UK stock assets. In addition, exchange rate volatility is found to
pose stern limitation on the potential benefits of this portfolio
diversification arrangement. It is therefore recommended that the monetary
authority in Nigeria should pursue policies towards reducing exchange rate
volatility to the barest minimum. This will possibly attract more investors
from developed economies who might be willing to combine Nigerian stock in
their investment portfolio to minimize portfolio risk.

Nigeria Economic Update (Issue 8)

The falling tide in the international value of Naira experienced a reversal in the review week with naira appreciating significantly by 11 percent from N516/$ on February 17, 2017 to N460/$ on February 24, 2017 at the parallel market the first appreciation since December 2016. The recent rise in naira value was driven by forex supply-demand gap closure, sequel to improvements in dollar liquidity. The recent CBN Special intervention (e.g. the auction and sale of $370 million and $1.5 million respectively, by the apex bank during the week) and its revised forex policy guidelinescontributed in dousing speculations in the parallel market, thus gradually narrowing the margin between the interbank and parallel market rates. Given that the sustainability of naira appreciation is strongly hinged on the improvement in foreign reserve which is largely dependent on crude oil sales, the government should continue its efforts at calming tensions in the Niger Delta region.
