I’ve seen the trading volume in terms of shares, but what is that in terms of dollars. It should be attainable from the number of shares times the average price of each share.
Admittedly, I seem to be having trouble locating the trading volume in shares right now. I know I’ve seen it reported.
Ok, from here it looks as if volume on the NYSE was 4.480 billion shares and on the Nasdaq it was 1.840 billion shares. This doesn’t help that much though, since there may have been moreor less high value trades. I think the vast majority of stocks trade over $25 per share.
Are there really no investment wonks out there that can give a good estimate? I don’t expect a precise answer, but an approachable round figure would be great. Is the number in the trillions? Is it in the 100 billions? I think that it has to be that high just from multiplying the volume on individual stocks by there closing value.
Only assuming there’s no correlation between volume of trading and price of the share, i.e. high-priced shares are traded at exactly the same rate as low-priced shares.
From here, it appears that the dollar volume on the NYSE averages around a trillion per month.
And hereis the daily dollar volume for NYSE. Roughly $45-50 billion a day (which for a 20-day trading month would give you the $1 trillion figure Crotalus posted, which came from the same cite).
There is other data there but the site is rather wonky. I’m still looking for corroboration of these numbers.
Here’s some confirmation: http://www.knight.com/ourfirm/volumestats.asp
Seems to show about $32 billion a day for September (down from $41 in August).
This is a very important point. Before its reverse split, Citigroup accounted for an absurd amount of the share volume traded daily. However, the notational value traded wasn’t nearly as large as a percentage of the market.
Here is a list of stocks sorted by average daily volume. Export to Excel, mulitply average daily volume by price, add them up, and you should have your answer.
When looking at exchange, ECN, or broker-dealer volume statistics many times they are referring only to their volume. In your link the $32b figure refers to shares traded by Knight.
The link above to the NYSE data also is only referring to trades done on the NYSE, who doesn’t account for the majority of volume traded on NYSE listed stocks.
Too late to edit…
Hereis a more complete list of stocks sorted by avg. daily volume.
Just looking at SPY (S&P 500 ETF), you have $39 billion per day.
Are you looking for a number for any given day, or for an average? In 2010, the value of equity, bond, and ETF transactions processed by NSCC (which settles almost all broker-to-broker transactions in the United States) was $217.5 trillion (source: DTCC's Businesses, Subsidiaries & Joint Ventures | DTCC). Assuming there were 252 business days in 2010, that works out to about $863 billion per day. The number would be considerably larger if you included transactions in government securities, which change hands much more frequently.
Thanks for straightening that out, Trom. The numbers certainly seemed low.
Thanks guys. I think those are the numbers I was interested in.
