From their announcement this morning:
After trimming two pages from our daily listings of stock and mutual fund prices last week, we are returning a few hundred stocks and mutual funds to that list in response to reader requests.
Starting today, we will publish trading information on 1,400 stocks and 2,100 mutual funds. The list now includes shares of the biggest companies and mutual funds, stocks issued by local companies and those stocks and funds held by a large number of Post readers.
Full listings of individual stocks and mutual funds will continue to appear in Sunday Business. Monday’s Washington Business will continue to publish expanded data on local stocks. You can find up-to-the-minute stock quotes, mutual fund data and investing tools at http://washingtonpost.com/markets.
