    Employing the prespecified variable approach to APT factor identification on the segmented Johannesburg Stock Exchange

    Item type: Journal Article • Journal: South African Journal of Accounting Research
    Prior research has provided evidence that the return generating process on the Johannesburg Stock Exchange (JSE) is dichotomous in nature (Campbell, 1979; Gilbertson and Goldberg, 1981;Carter, 1983; Page, 1986, 1989; Venter, Bradfield and Bowie, 1992). More specifically, this prior work...
  2. Macroeconomic variables and the Johannesburg Stock Exchange: A multifactor approach

    Macroeconomic variables and the Johannesburg Stock Exchange: A multifactor approach

    Item type: Journal Article • Journal: De Ratione
    This study estimates the simultaneous relationship between a number of selected macroeconomic variables and share prices on the Johannesburg Stock Exchange (JSE). A linear factor model identical in form to that assumed by the arbitrage pricing theory (APT) is estimated...
  3. Diversification and the realised volatility of equity portfolios

    Diversification and the realised volatility of equity portfolios

    Item type: Journal Article • Journal: Investment Analysts Journal
    In Markowitz’s (1952) portfolio theory, a reduction in volatility for a given level of expected return is implied as being equivalent to an increase in diversification. The recent development of risk-based portfolio construction methods, which emphasise diversification separately from volatility...
  4. The inflation hedging properties of South African and international asset classes

    Item type: Journal Article • Journal: South African Forestry Journal
    Mechanical as well as visual tensile stress grading of Southern African Eucalyptus grandis is discussed. Results of a large number of tests are presented. Correlations between bending stiffness and tensile strength, between density and tensile strength, amongst others, are shown...
  7. Response of <em>Eucalyptus</em> to Aldicarb in Coastal Sandy Soils in Natal, South Africa

    Item type: Journal Article • Journal: South African Forestry Journal
    The planting of Eucalyptus on aeolian; recent sands of the Natal coast has raised the question of whether nematicides are as necessary to counter patchy, unthrifty growth, as they are for sugarcane. The heights of eucalypts were mea sured at...
  8. Derivation of Grade Stresses for South African Pine Plywood

    Item type: Journal Article • Journal: South African Forestry Journal
    Very little use has been made of plywood in engineered timber structures in South Africa. One of the reasons could be that little or no information was available regarding the mechanical properties of the currently produced S.A. pine plywood. This...
  9. S A Pine—Load Sharing. Fact or Fiction?

    Item type: Journal Article • Journal: South African Forestry Journal
    Load sharing amongst timber members, that are restrained to the same deflection, has been accepted as a given fact for some time. This paper discusses a simulation method that can be used to determine whether load sharing does in fact...
