The FTSE 100, the index of large caps in London, still sits below its 1999 high! I myself have had some luck finding some value on the London Stock Exchange, though mostly with smaller names. To track the filings of these stocks, I have now made notifications available on conferencecalltranscripts.org for stocks on the LSE.
So all in the same place, you can now get filing notifications on American, Canadian, Australian and now English companies.
As always, let me know if you experience any difficulties with the site or have ideas for making it more useful.
