After scoring the largest one-week gain in stock market history with the Dow Jones Industrial Average up more than 100 points, the activity and interest seemed to center only on institutional favorites, said Irving Katz, director of research at Thomas Green/San Diego Securities.

The few San Diego stocks that participated were led by Rohr Industries, up $2.875 to $29.875 after reaching a 1988 high of $30. Some of the activity might be attributable to a multimillion-dollar Boeing airplane contract of which Rohr is a prime subcontractor. In addition, earnings trends have been upward the last few quarters.

Other institutional favorites that moved up were Fisher Scientific Group, up $1.25; Price Co., up $1; and Henley Group, up $1.375. Henley Group announced Monday that it had recently purchased 1,622,500 shares of Santa Fe Southern Pacific, raising its holdings from 15.7% to 16.7%.

Some of the interest-sensitive savings and loans participated in the rally, including Home Federal Savings, up $1.625; Imperial Corp. of America, up $.875; and Great American First Savings Bank, up $.625.

According to a listing of institutional holdings in Barron’s financial weekly, institutional investors held 81% of Fisher Scientific Group stock and 79.5% of Home Federal Savings stock.

Advanced Marketing Services, the supplier of books to wholesale membership clubs, rose $1.50 after a favorable mention in Fortune magazine and inclusion in the Business Week list of best small companies.

Wavetek gained $.25 to 7, despite an announcement by a New York investment firm that it would like to sell its block of stock representing 20.35% of the company’s outstanding shares.

BSD Bancorp, which gained $.375 to $4.625, will hold its annual meeting today at 5 p.m. at the Sheraton Harbor Island.
