Zurich — What is the window-dressing effect, and how does it affect equity markets? What influence can this effect be expected to have as December 2024 draws to a close? Silvano Grimaldi, CEO of the independent asset management firm Grimaldi & Partners AG, answers these questions.
What Is the Window-Dressing Effect?
The so-called window-dressing effect describes a strategy used by institutional investors and fund managers to make their portfolios appear particularly attractive at the end of the year.
This often occurs during the final days of December, when funds seek to present investors with strong performance figures in their annual reports.
To achieve this, fund managers sell loss-making securities and replace them with shares that appear more promising or have performed particularly well.
This effect can create an artificial increase in the value of certain shares and influence market movements towards the end of the year.
Positive Effects on Equity Markets
The window-dressing effect can have a positive short-term impact on equity markets.
As funds frequently invest in strongly performing shares, demand for these securities may increase.
In particular, shares of blue-chip companies or sectors with strong year-end momentum, such as technology and healthcare, could experience upward movements during the final days of December.
These purchases may support the market, improve overall investor sentiment and strengthen the traditional Santa Claus rally.
Negative Effects on Equity Markets
However, the window-dressing effect also involves certain risks.
The artificial increase in share prices may distort the true condition of the market.
After the beginning of the new year, when funds no longer need to enhance the appearance of their portfolios, these shares could be sold again.
This could lead to a market correction in January.
In a weak market environment or during a global recession, this correction could occur more quickly and be more pronounced.
Outlook for December 2024
Given the current economic and geopolitical uncertainties, the window-dressing effect is likely to have a mixed impact on equity markets in December 2024.
Although some sectors could experience short-term price increases, fundamental uncertainties related to inflation, economic growth and geopolitical tensions may prevent the effect from being as strong as in previous years.
It is important to remember that the window-dressing effect is only one of many factors influencing equity markets, and its impact can vary considerably from year to year.
