Global stock markets seem to have reacted in a coordinated way to the systemic risk triggered by the Covid-19 pandemic. In the midst of the crisis though, the S&P 500 index has recovered 75% of its losses while the Eurostoxx 50 only bounced back a mere 55% from its trough. Be it due to different domestic policy responses, or to the simplified view that regional blocks specialise in different segments along the global supply chain, the underlying idea is that recovery expectations diverge across stocks markets. For equity investors, such discrepancies present an opportunity to efficiently allocate their capital. The aim of this challenge is to put yourself in an equity portfolio manager's shoes and make the most of each individual stock market behaviour.

Construct a portfolio that invests in global equity indices. You can buy or sell equity index futures across Europe, Asia and America to build a portfolio with the highest returns. Use leverage to cash in on regional or country trends.



Build a global equity index portfolio which maximises returns. The portfolio can be long or short. Use machine learning techniques in your payout in order to learn from data.

Investment universe

You can invest in building blocks of the most prominent equity indices in the world across all continents. Consider they can be mixed up directly within a portfolio in their local currencies. You can be long and short. You cannot use leverage on individual assets (your position spans between -100% and +100%) but you can have some leverage in the portfolio: net leverage (sum of all weights) in the portfolio cannot exceed 200%. The same rule applies on the short side. Overall, portfolio net leverage has to be between -200% and +200% at all times.
