Value investing versus growth investing in South Africa : valuation disparities and subsequent performance

[摘要] ENGLISH ABSTRACT:Investment styles and more particularly the relative outperformance of certain styles under differing market conditions have been widely researched. Furthermore, investment professionals are constantly on the lookout for factors that could possibly be indicative of the subsequent outperformance of certain investment styles. With the value-growth phenomenon at the centre of this debate, there is an attempt in this study to shed some light on this anomaly from a purely South African perspective.Using monthly data for the period 1991 to 2011, and calculating price-to-book value (P/B) ratios for all the stocks included in the FTSE/JSE All-Share Index, the methodology employed by The Brandes Institute (2009A), based on work of Lakonishok, Shleifer and Vishny (1994), will be utilised in this study in order to determine whether the relative outperformance of value stocks over growth stocks can be anticipated in advance.Stocks were ranked monthly on the basis of their relative P/B ratios and subsequently four new portfolios were created each month, with the growth portfolio consisting of the highest 25% P/B ratio stocks and the value portfolio capturing the lowest 25% P/B ratio stocks. After portfolio creation, quartile-by-quartile performance was tracked over the following five years. The relative performance of the value versus growth portfolio was compared to the valuation difference multiple, calculated as the median P/B ratio of the growth portfolio divided by the median P/B ratio of the value portfolio, to determine if a relationship existed between valuation disparities and the subsequent relative performance of value and growth stocks. The all-cap (FTSE/JSE All-Share Index) segment was further divided into large-cap (FTSE/JSE Top-40 Index), mid-cap (FTSE/JSE Mid-cap Index) and small-cap (FTSE/JSE Small-cap Index) segments in order to determine if a consistent relationship could be identified within different market capitalisation sectors of the market.A significant relationship was found between the valuation difference multiple and subsequent performance of value and growth stocks in all segments of the JSE Mainboard. Historically, the higher the valuation difference multiple, the higher the subsequent outperformance of value stocks over the subsequent five-year period, as compared to growth stocks. This was found to be significant within the FTSE/JSE All-Share Index, the FTS/JSE Top-40 Index, the FTSE/JSE Mid-Cap Index and the FTSE/JSE Small-Cap Index. An exception to the above findings was the post-2002 period within the FTSE/JSE Top-40 Index. During this period it was not possible to identify a relationship between the valuation difference multiple and subsequent value stock outperformance.
