Under the “Don’t put all your eggs in one basket” analogy, the eggs represent 1 / 1 point
individual investments and the basket represents the overall investment portfolio.
Spreading your “eggs” around allows you to:
Increase the uncertainty of your overall portfolio so you can try to generate an extra
return.
Maximize the return of your overall portfolio.
Maximize the possibility that good luck for a single investment positively affects your
overall portfolio.
Minimize the possibility that bad luck for a single investment adversely affects your
overall portfolio.
Correct
This is the principle of risk diversification. By spreading the “eggs”, you allow
for an under-performing investment to be balanced by another and
outperforming one.
2. Risk diversification can be better achieved: (check all that apply) 1 / 1 point
By including in your portfolio all classes of assets traded in the market,
independently of their risks.
Correct
Including all asset classes allows you to “average out” the extent of all
potential sources of risk.
With only stocks in your portfolio.
With only low risk assets in your portfolio.
With mutual funds or unit investment trusts if you hold a small number of assets.
Correct
Diversification for individual assets is harder since you would have to buy
fraction of other assets, which could be impossible or prohibitively expensive.

3. Short selling, which is defined as the sale of a security that the seller has borrowed, is 1 / 1 point
motivated by the belief that:
The price of the security will decline.
The price of the security will rise.
Short selling is never prompted by speculation.
The price of the security will stay the same.
Correct
Buying back the security at a lower price will allow you to make a profit.
4. The expected return of a portfolio is computed as ___________ and the standard 1 / 1 point
deviation of a portfolio is ___________.
the weighted average of the expected returns of each asset in the portfolio,
weighted by the investment in each asset
the weighted average of the standard deviations of each individual asset
the simple average of the expected returns of each asset in the portfolio
NOT the weighted average of the standard deviations of each individual asset
the simple average of the expected returns of each asset in the portfolio
the weighted average of the standard deviations of each individual asset
the weighted average of the expected returns of each asset in the portfolio,
weighted by the investment in each asset
NOT the weighted average of the standard deviations of each individual asset
Correct
