Unibail-Rodamco-Westfield SE (previously Unibail-Rodamco SE) is a European commercial real estate company headquartered in Paris, France. Its history originates with the formation of two separate shopping centre operators, Unibail (founded in France in 1968) and Rodamco Europe (founded in the Netherlands in 1999), which merged in 2007 and became a societas Europaea in 2009. The company acquired Australian shopping centre operator Westfield Corporation in June 2018. As of 2018, Unibail-Rodamco-Westfield is the largest commercial real estate company in Europe, and is a component of the Euro Stoxx 50 stock market index, as well as the French CAC40. Its portfolio consists of retail property, office buildings, and convention centers within Europe and North America. Many of its shopping centres use the Westfield brand launched by Westfield Group in 1960 and shared with Scentre Group for properties in Australia and New Zealand since 2014. Retail properties owned by Unibail-Rodamco before the merger carry the Westfield name. The group currently owns 87 shopping centres. (https://en.wikipedia.org/wiki/Unibail-Rodamco-Westfield)

In the table below you can see the date that a signal was issued, the type of signal (buy versus sell), whether the signal was issued in the forecast period, and the closing price of the stock on that day. The graph below, therefore, resembles the graph above to a certain extent, only without the forecast.

How well is the Trading Robot doing? For this, we make a simulation of 12 months each time. We calculate the return the trading robot would have made if you had followed signals for this fund. And we compare the result with if you would do nothing. That is, on day one you buy the fund and 365 days you sell the stock.


This simulation is repeated 31 times. The difference is that with each subsequent simulation the period shifts by one month. When shifting the 12 months, the simulation only looks at the buy and sell signals from that particular period.
The return of the Trading Robot is calculated as follows.

  1. the difference between the price of the fund between selling and buying (of 1 share of the relevant fund)
  2. we calculate the cumulative difference for multiple buy and sell signals
  3. if there has been no sell signal at the end of the 12-month period, we use the price on the last day of the 12-month period
  4. we calculate the average price value of a buy signal
  5. the cumulative difference divided by the average price is the return over the 12 months

The Profit HR (Trading Robot Profit) is the cumulative difference between buy and sell signals of 1 share of the relevant fund
The return of the Trading Robot is the Profit over the last 12 month divided by the price value of the first day of a 12-month period of the relevant fund
