While the Dow Jones average flirted with the 1900 mark, several interest-rate-sensitive San Diego stocks hit new highs last week, according to Irving Katz, director of research at San Diego Securities.

Chairman Gordon Luce’s forecast of second quarter earnings sparked Great American First Savings Bank to hit a new high of 23 1/2, closing the week up 3 7/8 to 22 7/8.

Other interest-rate-sensitive stocks followed suit. Home Federal Savings & Loan reached a new high of 38 5/8, Imperial Corp. of America hit a new high of 16 and SDG&E; marked a new high of 36 3/4.

Intermark also hit a new high of 21, in continued sympathy with its majority-owned Pier 1 Imports, according to Katz.

Intermark Chairman Charles “Red” Scott will speak today at the first San Diego meeting of the Amex Club, scheduled for 1 p.m. at the Westgate Hotel.

Mail Boxes, which went public June 10 at 11 per share, hit a new high of 18 3/4, and rose 3 points for the week, closing at 18.

PSA dropped another 1 3/8, closing at 25, as transportation stocks lagged the general market. Airline analysts expect continued price wars, regardless of what happens to discount-flier Peoples’ Express, said Katz.

Molecular Biosystems continued downward from its recent high of 7, closing at 5 3/4, as tests for AIDS are announced by competitors.
