When a share changes its name/code, it seems that it loses all its history, etc, on OST. Look for example at ACD which now became ALM. Only price info if available, everything else seems to have gotten unlinked. There should be some way of tracing the share through all its changes - if I did not have ACD/ALM in my protfolio, it would have been difficult to see what the new name or code now is. Also I would think that automated updating people's watchlist to the new share code should not be that difficult - the portfolio does get updated. The share code changes happen quite frequently, so it is not an once-off problem. Hey Simon?...
