Wedbush sought a larger stake in Great American.

Wedbush Corp., a Los Angeles brokerage, sought permission from the Federal Home Loan Bank Board to increase its 9.8% stake in San Diego-based Great American First Savings Bank. If the bank board grants approval, Wedbush may buy up to 24.9% of Great American’s stock, although officials from both companies maintained that the filing did not signal an attempted takeover.
