Rules (2024-08-30)

  1. This is an English-language community. Comments should be in English. Posts can link to non-English news sources when providing a full-text translation in the post description. Automated translations are fine, as long as they don't overly distort the content.
  2. No links to misinformation or commercial advertising. When you post outdated/historic articles, add the year of publication to the post title. Infographics must include a source and a year of creation; if possible, also provide a link to the source.
  3. Be kind to each other, and argue in good faith. Don't post direct insults nor disrespectful and condescending comments. Don't troll nor incite hatred. Don't look for novel argumentation strategies at Wikipedia's List of fallacies.
  4. No bigotry, sexism, racism, antisemitism, islamophobia, dehumanization of minorities, or glorification of National Socialism. We follow German law; don't question the statehood of Israel.
  5. Be the signal, not the noise: Strive to post insightful comments. Add "/s" when you're being sarcastic (and don't use it to break rule no. 3).
  6. If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
  7. Light-hearted content, memes, and posts about your European everyday belong in other communities.
  8. Don't evade bans. If we notice ban evasion, that will result in a permanent ban for all the accounts we can associate with you.
  9. No posts linking to speculative reporting about ongoing events with unclear backgrounds. Please wait at least 12 hours. (E.g., do not post breathless reporting on an ongoing terror attack.)
  10. Always provide context with posts: Don't post uncontextualized images or videos, and don't start discussions without giving some context first.

(This list may get expanded as necessary.)

Posts that link to the following sources will be removed

Unless they're the only sources, please also avoid The Sun, Daily Mail, any "thinktank" type organization, and non-Lemmy social media. Don't link to Twitter directly, instead use xcancel.com. For Reddit, use old:reddit:com

(Lists may get expanded as necessary.)

Ban lengths, etc.

We will use some leeway to decide whether to remove a comment.

If need be, there are also bans: 3 days for lighter offenses, 7 or 14 days for bigger offenses, and permanent bans for people who don't show any willingness to participate productively. If we think the ban reason is obvious, we may not specifically write to you.

If you want to protest a removal or ban, feel free to write privately to the primary mod account @EuroMod@feddit.org

Ideally located in Germany, subject to German law and regulation, German taxes, and German national security interests, right?

[–] RidderSport@feddit.org 7 points 1 week ago

Probably yes, though to be fair European legislation has changed so much already that quite a few areas of the law have little national legislation left.

[–] Melchior@feddit.org 15 points 1 week ago (1 children)

Having a unified financial market makes sense, but having multiple stock exchanges is also a good idea. The US has New York and NASDAQ. Currently the EU has Euronext, DAX and NASDAQ Nordic and Baltic.

[–] oneser@lemmy.zip 5 points 1 week ago (1 children)

And Paris, and Vienna and Budapest and .... (link)

Maybe some consolidation wouldn't be a bad idea, but given how the markets are at the moment I would expect a significant crash is needed before anyone would give up their exchange.

[–] Melchior@feddit.org 2 points 1 week ago

There are already some large players and it is pretty likely that they just buy out smaller exchanges and then integrate them into a larger multinational one. Euronext is already quite far along in that process.

[–] Paragone@lemmy.world 6 points 1 week ago (1 children)

um, you REALLY might want to have 4, not 1, for redundancy, given how Russia's going to be waging WAR against the EU as soon as Trump guts NATO, you know?

[–] Atherel@lemmy.dbzer0.com 1 points 1 week ago

But then how will he manipulate the market like Trump does.

[–] Treczoks@lemmy.world 5 points 1 week ago (1 children)

He is not the smartest, but this is one of his dumber ideas.

[–] tired_n_bored@lemmy.world 16 points 1 week ago* (last edited 1 week ago) (2 children)

Why? Most stock exchanges are managed by Euronext anyways and having a single center of exchange improves liquidity and availability of assets

[–] randomname@scribe.disroot.org 4 points 1 week ago* (last edited 1 week ago)

I get your point, but market fragmentation must not necessarily translate into a worsening of liquidity compared to having one consolidated order book. We have the technological means where investors can gain access to multiple trading platforms simultaneously at low cost, including low search costs for investors (to identify the lowest possible price to execute a particular order).

Maybe more importantly, many long-term investors would argue that there can also be too much liquidity. Among my favorite citations regarding this has been for years Warren Buffet's Berkshire Hathaway shareholder letter of 1983:

One of the ironies of the stock market is the emphasis on activity. Brokers, using terms such as β€œmarketability” and β€œliquidity”, sing the praises of companies with high share turnover (those who cannot fill your pocket will confidently fill your ear). But investors should understand that what is good for the croupier is not good for the customer. A hyperactive stock market is the pickpocket of enterprise.

Former U.S. Fed chief Paul Volcker also made similar remarks about "too much liquidity" regarding the bond market if I remember that correctly.

There is also a more recent study investigating this issue. In, "Is too much liquidity harmful to economic growth?", the authors conclude:

... there exists a threshold, above which the marginal effect of financial liquidity on economic growth changes from positive to negative. In particular, the turning points for which domestic credit to private sector and stock market turnover start having negative effects on growth are 104% GDP and 107% respectively. Moreover, although the thresholds in middle- and low-income countries are higher than those in high-income countries, the growth-enhancing effect of financial liquidity is stronger in high-income countries.

Having said that, we must also consider the different dimensions of liquidity. Resilience is a strong point (measured by price volatiliy, the Amihud ratio) or the immediacy (e.g., the number of market makers, possibly related to the number of market participants), and many other metrics.

So I am not sure whether a consolidation of stock markets is a good thing, especially not for the long-term investor.

And helps concentrating the wealth even more. Exactly what Europe does NOT need.

[–] randomname@scribe.disroot.org 2 points 1 week ago (1 children)

How would stock market consolidation concentrate wealth?

[–] Treczoks@lemmy.world 1 points 1 week ago

By making trades and therefore speculation even faster.

What we seriously need is a way to slow the markets down, like a tax on trading. Why is there a 7% tax on groceries, but none at all on buying shares?

[–] tired_n_bored@lemmy.world 2 points 1 week ago

I agree that concentrating wealth sucks but won't be a unified stock exchange to make things worse

[–] kossa@feddit.org 4 points 1 week ago

I have no expertise and opinion about that.

I just know from extrapolating, that if Merz wants it, it is probably a bad idea for everyone Β―\_(ツ)_/Β―

That's a great idea. Maybe that exchange could then set the prices for the shares daily so that everybody can profit from fair prices. We should also create a European center of competence for strategic investments. That center could calculate the best opportunities for companies and help them make the best investment decisions and help them allocating their work force.

This is madness. If we believe in markets then we should have competing exchanges.

[–] hitmyspot@aussie.zone 2 points 1 week ago

There's an argument for competition and an argument for streamlining the purpose of exchanges, to make easy exchange possible. A trans European exchange linked with the individual exchanges wouldn't be a bad idea. But most of the benefits are already present in trading platforms that are seperate, already, as digital cooperation has increased.
