Exhibit 99.1

SWS Group Reports Net Income of $31.9 Million for Fiscal 2008

Fourth Quarter Diluted EPS of 31 Cents versus 25 Cents

DALLAS, August 27, 2008 – SWS Group, Inc. (NYSE: SWS) today reported net income of $31.9 million, or diluted earnings per share (EPS) of $1.17, on net revenues of $301.6 million for fiscal 2008, compared with net income of $37.6 million, or diluted EPS of $1.38, on net revenues of $273.6 million for fiscal 2007. Net revenue is total revenue less interest expense.

For the fourth quarter ended June 27, 2008, SWS recorded net income of $8.4 million, or diluted EPS of 31 cents, on net revenues of $87.8 million, compared with net income of $7.0 million, or diluted EPS of 25 cents, on net revenues of $65.5 million in the fourth quarter of the prior fiscal year.

A $1.1 million extraordinary gain, 4 cents per diluted share, from the acquisition of M.L. Stern & Co. is included in net income for the fourth quarter and fiscal year just concluded.

Adjusted income from continuing operations was $30.9 million, or diluted EPS of $1.13, in fiscal 2008, compared with $34.5 million, or diluted EPS of $1.26, in the prior fiscal year. In fiscal 2007, the adjustment eliminates the 3 cents per share impact of the company’s investment in NYX common stock and the 8 cents per share gain from company-owned life insurance proceeds. (See Non-GAAP Reconciliation table at the end of this release.)

“We are very pleased with our quarterly and annual financial results considering the disruptions the financial industry has experienced over the past year,” said President and Chief Executive Officer Donald W. Hultgren. “Our institutional businesses – securities lending, fixed income, municipal securities and investment banking – had an outstanding year and fourth quarter. Our retail brokerage, clearing and banking segments made progress toward their business goals in spite of turbulent markets and a tough economic environment.”

Hultgren said the results of M.L. Stern & Co., which were included in SWS Group’s consolidated financial statements for the fourth quarter, made a positive contribution to the company’s retail segment. “M.L. Stern and Tower Asset Management are excellent additions to our private client business,” he said. “Our associates at M.L. Stern will play an important role in growing our brokerage business.”

“Many of our business lines are in a building period,” Hultgren continued. “Our Clearing Services Division, for example, has incurred heavier than usual expenses as the new head of clearing restructures that business to enhance the correspondent’s experience, increase operational efficiency and drive future growth. We believe the investment we’re making in building our business segments will reward our shareholders as those efforts mature.”

Hultgren said the bank continued to diversify and increase its lending in areas that are experiencing good demand such as commercial, small business and commercial real estate. He said interest rates began to stabilize in the fourth quarter of fiscal 2008, resulting in improved net interest margins. “We are continuing to recruit experienced bankers and open new, full-service banking centers,” Hultgren said. The bank recently had a grand opening for its new banking center in Waxahachie, Texas and will open its first out-of-state banking center in Ruidoso, New Mexico in a few weeks.

The company’s net revenues increased $28.0 million from fiscal 2007 to fiscal 2008. Commissions increased $21.0 million, net interest increased $10.7 million, investment banking, advisory and administrative fees improved $4.1 million, and net revenue from clearing organizations rose $1.5 million. The rise in commission revenue primarily resulted from the acquisition of M.L. Stern and higher commissions in the fixed income business. Net interest revenue improved because of an improved spread earned on securities lending balances, investments in tax-exempt municipal auction rate bonds and higher average loan balances at the bank. An increase in money market fees and fees from M.L. Stern resulted in increased investment banking, advisory and administrative fee revenues. These increases were partially offset by a decrease in net gains on principal transactions of $6.8 million. The prior fiscal year included a $1.2 million gain on the value of NYX stock as well as a $2.7 million gain on the restructuring of a commercial mortgage backed security. Trading profits were also reduced in fiscal 2008 as a result of carrying lower inventories.

Operating expenses increased $35.1 million for fiscal 2008 as compared with operating expenses for the prior fiscal year. Commissions and other employee compensation increased $23.9 million. Occupancy, equipment and computer service costs increased $3.6 million, and other expense increased $6.7 million. Compensation expenses rose as a result of the acquisition of M.L. Stern in the fourth quarter and expenses related to the employment of a new head of clearing and new lenders and staff at the bank. Occupancy,

equipment and computer service costs increased primarily because of increased maintenance expenses for the CSS software system and new branch offices in the retail, institutional and banking business segments. Other expense increased as a result of higher professional and legal services costs of $4.2 million as well as an increase in the provision for loan loss of $2.9 million.

Net revenue for the fourth quarter was $87.8 million, an increase of 34 percent over net revenue for the fourth quarter of fiscal 2007. Pretax income of $11.4 million was up $451,000, or 4 percent, over pretax income recorded for the prior year’s fourth quarter. The increase in net revenue was driven by the M.L. Stern acquisition, increased net interest revenue from improved stock loan spreads, and improved results in the corporate finance and fixed income businesses. While pretax income in the institutional segment increased 163.5 percent in the fourth quarter of fiscal 2008 from the prior year period, this increase was offset by increased expenses in the other segments.

Southwest Securities processed 31.6 million securities transactions in fiscal 2008 compared with 17.4 million in fiscal 2007, an increase of 82 percent. The firm served 201 correspondents at the end of fiscal 2008.

Non-GAAP Reconciliation

SWS has included the presentation of income from continuing operations and diluted earnings per share from continuing operations, excluding the impact of the gain realized from our investment in NYX common stock and the proceeds from company-owned life insurance. SWS believes this presentation is useful to investors because it is more indicative of SWS’ income and diluted earnings per share from ongoing operations. Management has provided this information to assist the reader in understanding the impact of our investment in NYX common stock for fiscal 2007 and fiscal 2008 and the gain recognized on company-owned life insurance in fiscal 2007. While management believes these non-GAAP financial measures are useful in evaluating SWS, this information should be considered as supplemental in nature and not as a substitute for or superior to the related financial information prepared in accordance with GAAP.
