While the UK has seen a larger exodus from equity funds since 2020 than Paris, companies have raised more money in initial public offerings (IPOs) in London and more shares change hands in British markets every day.
France's CAC All Shares index is now worth almost $3 trillion, making it Europe's largest stock market by value thanks to demand for its luxury-retailer blue chips.
London's FTSE All-Share index, meanwhile, is worth $2.8 trillion, according to Refinitiv data.
Closing the gap
So far in 2022, funds investing in UK stocks have seen record outflows of 23 billion euros, according to Refinitiv Lipper, up from almost 18 billion euros last year and the 14.6 billion euros shed in 2016, when Britain voted to leave the European Union.
Annual outflows from French equity funds are much smaller - at 2 billion euros this year.
Bye London, au revoir Paris Bye London, au revoir Paris
But London remains a much larger destination in terms of number and volume of initial public offerings, even with IPO volumes down 80% in Europe this year from last and more than 90% in the United States, according to Dealogic.
After recording in 2021 its second strongest year for company listings since 2007, the London Stock Exchange has seen 41 debuts with a total deal value of 1.18 billion euros ($1.22 billion) so far in 2022, more than double the 474 million euros raised in 11 IPOs in Paris, according to Dealogic.
Amsterdam - Europe's largest centre by average daily value traded according to CBOE data - has only seen two IPOs so far this year totalling 411 million euros, according to Euronext.
More IPOs in London
In a volatile stock-market environment, Paris can count on large privately held stakes in its companies to offer some stability.
The average free-float of French large caps is around 70% and for smaller companies around 50%, according to Euronext, well below London where the average free float of the FTSE All-Share Index is almost 90% of total outstanding shares, according to Refinitiv.
"For an institutional investor from an investability standpoint, the amount of free float that is still out there, the UK is still significantly bigger," said Ben Laidler, global macro strategist at eToro.
Indeed, Paris' three biggest shareholders are private investors: the Arnault family, who own half of LVMH - Europe's largest company by market capitalisation - the Hermes family and the French government. In comparison, the world's largest asset manager Blackrock leads the way in London.
In terms of market activity, Amsterdam's average daily value traded was more than 10 billion euros in October, with London a close second at 9.4 billion - about the same as Paris and Frankfurt combined, according to the data from CBOE Global Markets.
Undermining London is the discount at which the FTSE All-Share index trades relative to world stocks, which since the Brexit referendum in 2016 has grown to near its largest since 1990, at 35% on a price-to-earnings metric.

DIVIDENDS AND PRICE RETURNS
Energy-heavy London wins big when it comes to dividends. In the third quarter, UK companies paid out $28.7 billion, more than seven times the total paid in France, according to Janus Henderson Investors' Global Dividend Index.
London's FTSE All-Share has also delivered better returns to investors this year. Total annualised returns for the index are 2%, compared with returns of almost minus 6% for the CAC All Shares, according to Refinitiv data.
It's also worth noting that currency comes into play when measuring the size of London's market against Paris' in dollar terms. Sterling has fallen around 11% against the U.S. dollar this year, while the euro has lost around 9%.
