I've been using Yahoo's finance.uk pages to display my portfolio.
Today I looked and it said BT, under the symbol bt.a.l at 0 last
traded 1970.
Is this a cock-up or has the ticker symbol changed.
Yahoo's own symbol look-up only gave bt.l which again was valued at
0.
The proper symbol for British telecom is BT.A, plus whatever prefix or
suffix is needed to define the exchange. It sounds like Yahoo have
been taking a shortened version, but suddenly got fussier.
Having just had a try, they now need BT-A with a hyphen instead of the
dot. The note on the link from their quotes page says:
Dear Users, We are changing the quotes data provider for Y! Finance in
the next few weeks. Y! Finance is switching all European exchanges
from Reuters to our new data provider Telekurs Financial. We would
like to give you advance warning about any changes you might notice
during the switch so your use of Y! Finance continues without any
hitches
And:
If you are tracking a lot of stocks and other securities in your
portfolio, some quotes may not update after the switch. The reason for
this could be that you're using a Reuters-specific symbol for the
stock that is no longer supported by our new quotes provider Telekurs.
For example the Reuters ticker for the stock Yahoo! is "YHOO", but the
Telekurs ticker for Yahoo! is "YHO". You then just need to update the
entry in your portfolio. Please visit the Help with updating your
portfolio page and the How to modify your portfolio page.".
