Thanks for your post, sounds to me as the source you describe is also the source that the individual banks get their info from? I find it always hard to tell on a forum who is actually in the know as many people are often just acting that way, but sounds to me you know more than you get credit for (which would also explain why many posts following yours report the same info from different brokerages). Maybe you can explain what Clearstream does exactly...
no prob, no worries...
Clearstream bank is depo that handles clearing for trading venues in germany. they have frankfurt and luxembourg. they are a CSD (central securities depository)
- basically same as DTCC is to US markets
- euroclear/Crest for u.k./ireland, french markets
- etc etc
the depos hold all the settled stock that trades on exchanges within their market venue
dtcc settles stock for all US trading (nyse/arca, bats, nasdaq, etc etc) but not until it passes through NSCC from T to T+ 1. on t+2 it either settles or it fails. dtcc also provides a litany of other services
europe is fairly de-centralized so it doesn’t have 1 NSCC equivalent but each market has its own CCP (central counterpart)
in this case EuroCCP tracks T and T+1 while Depo (CBF and CBL) accounts for the settled position
__________
for corp actions, what happens is:
- the company makes the announcement
- there are corp action data vendors:
Bloomberg, SIX (telekurs), Mediant, etc
also,
Exchanges sell corp action data along with market data and other stuff
the depositories themselves also disseminate this data to their market participants (dtcc corp action data is ‘free‘ but not really, it’s bundled with all the clearing stuff that brokers pay gobs of money for every month)
...in europe places like CBF and Euroclear use swift messages to disseminate the data, (usually at added cost)
- the core corp action vendors (Bloom, Six are amongst the largest) have programs and/or staff that read the sec docs and press release, scrub and field the data, and create an ‘announcement’
- basically everyone subscribes and pays for the top corp action vendors; brokers, funds, depos, exchanges, the banks,
- then some of those like dtcc or CBF will make their own announcement from that data, and disseminate
therefore a broker will receive numerous announcements for tesla’s split from all the ‘sources’ it pays for, directly or indirectly.
the broker then has corp action operations staff / and hopefully a smart and well built system that also scrub all these announcements to fit into one ‘event’ in a db that is responsible for all the key critical criteria needed to for ‘posting’ the event accurately to its ‘customers’ that hold tesla as of the ex date
but that’s why it’s important to read all of the banks’ SWIFT messages and the original source announcements, because there’s often a human entering some info somewhere and is subject to error. i never saw a tax implication on a standard forward split such as this, but i’m not a tax expert that knows every country’s quirks
