About this time of the year, the old family argument kicks off over which colour lights to put on the Christmas tree. Is it an elegant warm white (Gucci style), a flashy electric blue (to keep the dog amused), or the traditional but old fashioned red and green that are best picked out of the baubles, tinsel and seasonal chocolates?

At big xyt we believe that pink and purple is the answer. And as you can see from our first chart, one of the highlights we like to pick out is the Biggest Day of the Year. Despite the general lack of volumes, 2023 saw two new records set – first on the 17th March with €122B traded across the region, and then on the 31st May with a whopping €142B, of which €52B went through the Closing Auction and associated alternative mechanisms.  

Since 2018, seven of the top 40 days took place in 2023, driven as usual by index re-constitutions and expiry days. We had to wait three years for this record to fall, the previous best being €120B set on 28th February 2020 at the start of the Covid outbreak.

In our second chart we look a little deeper into the movers and shakers in Europe. In 2023, fewer names traded more than €500M a day (15 compared to 19 in 2022), and only two traded more than a billion (compared with three). 

Shell Plc knocked TotalEneries SE off the top spot and into fourth, while LVMH Moet Hennessy Vuitton SE climbed three places to third.

We seem to be filling our cars with fuel, buying more electronics and drinking more bubbly!  Feels about right. 

Many of our bespoke charts (such as these) are created using Tableau in our server environment, making it very easy to research the trends and patterns in the market landscape.
