Accounting and financial analyses are performed for an investment
portfolio to produce comprehensive reports on the performance and/or
current real net worth of this investment portfolio. These reports are
generated in response to a user request that is received over the
Internet based on automatically based on security price data retrieved
from a real-time security price reporting service and transaction records
of the investment portfolio that are retrieved from one or more of the
user's trading accounts that are kept at different financial
institutions. As a result, a single financial report that is
representative of the collective performance of different accounts in
different financial institutions can be generated.
