     Columbus,  Ohio -- August 12, 2005, -- Diamond Hill  Investment  Group,
Inc. (NASDAQ:DHIL) today reported unaudited results for the quarter ended
June 30, 2005.  Assets under management increased by 152% to $811 million
compared to $322 million at the end of the second quarter of 2004 while
investment management revenue increased by 166% compared to 2004.  Both assets

or $0.15 per share in 2004.

     Ric Dillon, president and chief investment officer stated, "Our primary
business objective is to produce investment returns for our clients.  I am
pleased that we have continued to deliver strong results.  All of our client
funds and portfolios are highly ranked compared to other investment firms.
Our efforts to market our mutual funds and managed portfolios resulted in $103
million in new client investments in the second quarter of 2005 compared to
$23 million in the second quarter of 2004."

make progress" but cautioned that "first half results included $471,000
in performance fees and investment returns on the company portfolio, both of
which can be volatile, particularly in the short-term."

review of the compensation of all staff and expects to finalize a new
compensation program by November 2005.  Performance bonuses, which are
expected to be significant, will be finalized by the fourth quarter.  The
Company anticipates that it will earn a profit for the full year including
the impact of the new compensation program.
