Let the game begin – quotas have changed, VIG Football World Cup Equity Portfolio Index rebalanced
The FIFA World Cup has not even started yet, but bookmakers’ decisions have already led to continuously changing odds, reshaping the field. Based on these odds, we can derive implied probabilities.
This logic underpins the hypothetical VIG Football World Cup Equity Portfolio Index.
The index is a conceptual model portfolio that weights leading equity indices of participating countries according to these implied probabilities. A more detailed introduction to the index can be found in our previous article.
A turning point in April
A dramatic twist occurred during the playoff match on March 31: Bosnia and Herzegovina knocked out one of the top contenders, Italy. As a result, Italy’s probability dropped to zero, and it was automatically removed from our hypothetical portfolio. This is a classic example of index exclusion – similar to a stock being deleted from an index. Colombia re-entered the portfolio in its place, triggering a rebalancing.
However, the most significant shift was not the exclusion itself, but the reshuffling at the top. France’s weight increased from 11.4% to 15.4%, marking the largest change within the VIG Football World Cup Equity Portfolio Index.
As a result:
- France moved up to 2nd place
- England dropped to 3rd place

The weight change was not only theoretical: during this period, the French equity market outperformed the UK market, meaning the rebalancing generated a virtual excess return.
The updated portfolio now looks as follows:

It is fair to say that the past two weeks have been particularly eventful: not only weights, but also countries and rankings have changed. The February changes can be found here.
What if we hadn’t reacted to these changes?
The impact of rebalancing on portfolio performance
Adjusting the weights of equities – or in this case, country equity indices – within our hypothetical portfolio represents a dynamic rebalancing process. Without such adjustments, the index would fail to reflect market developments: Italy would remain in the portfolio, or France’s weight would not increase.
Let’s take a look at the impact of rebalancing so far:

The chart shows the cumulative difference between the returns of the hypothetical VIG Football World Cup Equity Portfolio Index and the returns based on the January allocation. Since the two portfolios were identical until February, the performance difference is only shown from February 5 onwards.
The chart clearly indicates that rebalancing has had a positive overall impact:
- In February, outperformance reached 25 basis points
- By April 8, outperformance stood at 4 basis points
- Overall: positive value added
Our hypothetical index has performed strongly since its inception. Thanks to the combination of developed and emerging markets, it provides a well-diversified exposure, contributing to favorable virtual return dynamics.
Performance has evolved as follows:

The VIG Football World Cup Equity Portfolio Index is a hypothetical, classic market model that illustrates how markets function. Expectations change, weights adjust, and investors adapt accordingly. Markets are not efficient because they are always right, but because they continuously rebalance.
Why follow the development of our hypothetical portfolio?
We consider this to be an illustrative and educational tool that helps explain how probabilistic thinking works in financial markets.
When we ask whether Spain will face England or France in the final, we are in fact reflecting on how much confidence we place in market consensus – and how much weight we assign to alternative scenarios.
Both in the World Cup and in capital markets, the objective is not to predict a certain outcome, but to assess probabilities.
