Rohr Industries was the only San Diego stock to make a new high last week as it traded at 39, closing the week at 36 3/4, said Irving Katz, director of research for San Diego Securities. The stock moved up on financial analyst Dan Dorfman’s speculation that Boeing would acquire the Chula Vista-based company to help fend off takeover specialist T. Boone Pickens, Katz said.

Aerospace industry analysts, however, put little credence in that eventuality--or the threat of Pickens taking over Boeing, Katz said.

Agouron Pharmaceuticals was up 2 to 13 as the market digested an institutional research report issued by their underwriter, San Diego Securities. BSD Bancorp gained three-eighths to 4 as First National Corp. increased its initial, undisclosed offer for the assets of the Bank of San Diego.

Monitor Labs gained one-quarter to 2 7/8 as it announced earnings of 12 cents for its latest quarter and 22 cents for its first half compared to losses in the previous year, Katz said.

Burnham Pacific Properties gained three-quarters to 16 7/8 as it raised its quarterly dividend to 29 cents from 27 cents.

Other good gainers included Price Co., up 2 1/2 to 48, and Home Federal Savings & Loan, up 2 5/8 to 31 3/8.

On the down side, there was profit taking in Fisher Scientific Group, which dropped 1 1/2 to 19 3/4 despite reporting its second consecutive profitable quarter, compared to losses last year, Katz said.

Cipher Data Products was down five-eighths to 9 1/8 on large volume transactions as institutions were disappointed in its fourth-quarter earnings of 7 cents, compared to 26 cents during 1986, and yearly earnings of 36 cents, down from 50 cents during 1986.

An additional negative was the award of a $60-million optical disk data system by the U.S. Dept. of Commerce to Sony. Cipher Data, which had paired with 3M, had anticipated winning part of that contract, Katz said.

Continental Graphics, a division of locally based Triton Group, made a successful public offering of 1 million shares of stock at 10 1/2, with a simultaneous listing on the American Stock Exchange with the symbol CIG. Triton is a subsidiary of La Jolla-based Intermark.
