Ericsson is currently dual listed in
Stockholm in SEK,
New York in USD, and
Frankfurt in EUR. The SEK shares consist of A and B classes, while the USD and EUR listed shares are both equivalent to the SEK class B shares. This is a basic ADR structure traded through 3 currency pairs and 2 different class structures.
As evidenced in the first chart below, at the time of the recording, the USD-listed ERIC shares were equivalent in price to the SEK-listed ERIC.B shares. Note the ERCB shares correspond to the right axis and trade at a roughly 50% discount to USD shares. The Class A SEK-denominated ERIC.A shares trade at a discount to their own and USD-listed B Class equivalents.
This study incorporated the cash markets for the EUR/USD, EUR/SEK, and
USD/SEK exchange rates. The principles of
triangular arbitrage were incorporated to derive values across the structure.
The Currency Adjusted USD-value Shares:
The US-listed shares register a bid/ask as early as 3am CST and track the SEK-listed B shares.
The Currency Adjusted Openings:
As is usually the case for these studies, the outright share prices correspond to the left axis, while the spread value corresponds to the right axis.
USD-listed shares vs. SEK-listed A and B Class shares.
EUR-listed B Class shares vs. USD-listed B Class shares.
EUR-listed B Class shares vs. SEK-listed A and B Class shares.
A closer look at the turbulence in the bid/ask of the EUR-listed ERCB shares. I believe this is similar in nature to some of the research posted by
Nanex.
And in the closing 5 minutes, the SEK-listed ERIC.B shares experience some unusual turbulence. I don't like to speculate because this could have happened for any number of reasons (data integrity, software integrity, etc.), but judging by the increase in the bid/ask spread of the ERCB shares (EUR-listed), the market maker appears to have known it was coming.
A closer look at the overall spreads during the 8:30-10:30am CST market overlap. Again, in order as before.
USD-listed shares vs. SEK-listed A and B Class shares.
EUR-listed B Class shares vs. USD-listed B Class shares.
EUR-listed B Class shares vs. SEK-listed A and B Class shares.
