Richard, will the data in excess of what is available to your current beta testers now? Are we likely to see historical changes in the metrics or will the data be 'most recent available'. What i mean is will the metrics be a single number over the entire price series? I would like to test some mechanical systems using say a P/S ratio or market cap that changes over time for example.
We only plan to provide current fundamentals. Historical fundamentals are actually very difficult to get right.
Here's are some factors off the top of my head that really mess with historical fundamental data:
Stock dividends (bonus share offers)
Capital raising/Rights issues (i.e. dilutive events)
Conversion of hybrid debt/equity instruments
Exercise of warrants/company options
Employee share issues
Mergers/Reverse Mergers between companies that have different fiscal year boundaries
Reconciling differences between multiple sources of data that have different surviving entity interpretations for mergers/demergers
Multiple classes of stocks that have different ownership/voting rights - how many total shares actually exist for this company?
Companies that have large tranches of unlisted shares
Corporate re-orgs (e.g. creation of different classes of securities, with different ownership regulations)
Changes in fiscal year reporting dates
Changes in fiscal interim reporting frequency (some countries only require half-yearly accounts)
Changes in domicile/reporting currency
What currency value do you use for foreign currency-reporting companies? The value as at the report date? An average for the period?
Re-statement of most recent or previous periods (e.g. irregularities/mistakes)
Staggered reporting of financials (e.g. some companies just report the headline earnings figures and some weeks later provide the rest of the detailed balance sheet/earnings figures, so you have some fundamentals that are "current" and some that related to the previous period).
Tracking stocks that track only a portion of the company
To do this on an accurate and consistent basis historically is difficult and unlikely to be a sound business move on our behalf based upon the limited demand expressed so far.
I'm surprised that you have no plans to add other stock markets in the future, like say the London Stock Exchange. The London exchange is the 3rd largest in the world, after NYSE and NASDAQ. It’s a far larger market than Australia, yet you provide data for Australia, but not Lonon??
Regarding coverage of other exchanges - you'd be surprised how little demand there is for LSE. In order to cover an exchange correctly there's usually a few man-years of time to get it right prior to release. We actually spent some time a few years back looking at it and decided it wasn't commercially viable.
