  11. 11. Results- the least risky portfolio • Relying on the results, the best risk/return opportunities are presented by the first and the fourth portfolios. First portfolio offers higher standard deviation, at the same time it offers higher average return. Fourth portfolio is least risky with lower return. Markowitz risk/return tradeoff is confirmed there. • Those portfolios suit more to risk-averse investors or for those individuals who, according to Charles Jones (2010), view their wealth in spending phase. • According to Royal Bank`s formula of investing, such portfolios are more preferable for those who are not far from the retirement and do not like to take much risk.
  12. 12. Results- the most risky portfolio • The most risky is the second portfolio. For investors it is not recommended to construct such portfolios like the second portfolio, because the investor`s risk tolerance level should be very high there. • The third portfolio may be suitable for the young investors who are in the accumulation stage and can afford to take large risks. • Investors should remember: the higher the return, the higher the risk. • An investment may result in accumulation of investor`s wealth or dissipation of his resources.
