Country Valuation Differences Often Caused By Sector Structure

by: Norbert Keimling


Country valuations differ significantly across countries due to individual sector structures.

About half of the current US overvaluation is based on low exposure to attractively valued financials and overweight of expensive technology sector.

Investors should scrutinize undervaluations, particularly in smaller countries or in countries with a very divergent sector structure.

An attractive equity market does not always include attractive equities.

The old business adage "the profit lies in the purchase" also applies to financial markets. Numerous studies show that undervalued equity markets appreciate significantly more than highly valued ones over the long term. For investors, it is therefore an obvious step to compare the valuation levels of different countries and then to commit themselves to investments primarily in countries with attractive valuations.

For example, if one compares all established equity markets based on the price-to-book ratio, Asian markets such as Singapore and South Korea currently stand out due to their particularly attractive valuations, while Denmark and the US seem expensive. But is it really the case that all countries are comparable with each another in equal measure?

In particular, the case of Denmark raises doubts since the healthcare sector dominates the country's equity market in an exceptionally strong way. While this sector accounts for just 9 percent of the global equity market, it represents almost half of the Danish market (see Chart 1).

The fact that the global healthcare sector has consistently traded at a significant premium - 86% on average - to the global equity market in the past few decades raises the question of whether the Danish equity market with such a high weighting in a traditionally expensive sector will ever return to an average valuation level (see Chart 2).

Assuming that different sectors - e.g. due to industry-specific balance sheet structures - will also have different valuation levels in the future and that the sector structure of a market won't change dramatically in the medium term, it appears worthwhile to analyze the extent to which Denmark's overvaluation is simply the result of a higher healthcare weighting.

This effect can be quantified by comparing Denmark's valuation level with that of a sector-adjusted benchmark. For example, if the global equity market had the same sector composition as Denmark - including the high healthcare weighting - its price-to-book ratio would rise from 2.1 to 2.5. The Danish equity market would no longer be valued 46% higher than the global equity market, but only 23% (see Chart 3). As a result, half of Denmark's overvaluation is attributable to a divergent sector composition.

For all other established equity markets, it can be concluded that undervalued markets generally show undervaluations even after a sector adjustment, and vice versa. However, some undervaluations must be put in perspective, for example in Singapore, whose low PB ratio is largely due to a high weighting of financial stocks (with historically attractive valuations) (see Chart 4).

Systematically lower PB ratio in the financial sector - StarCapital, Keimling

In the seemingly attractive markets of Norway, Canada and Australia, the undervaluation actually turns into an overvaluation after a sector adjustment due to their high weightings of basic materials stocks and financial stocks. This means that equities in these countries are even valued higher on average compared to their competitors from other countries. However, this remains concealed in a classical PB country comparison.

The sector structure also has an effect on the high US valuation. Lower exposure to attractively valued financial stocks and an overweighting in comparatively expensive technology stocks inevitably cause the valuation of the US market to rise (see Chart 5).

If the global equity market had the same sector structure as the US market, its PB valuation would rise from 2.1 to 2.5. As a result, about half of the overvaluation is attributable to a divergent sector composition. This effect is similar for other valuation indicators (see Chart 6).

Investors should therefore scrutinize undervaluations, particularly in smaller countries or in countries with a very divergent sector structure. An equity market with a comparatively attractive valuation does not always include attractive equities.
