Last week saw the Dow Jones Industrial Average of 30 stocks twice break through the elusive 3000 barrier before falling back to close lower, according to Irving Katz, an independent stock market analyst in San Diego.

Still, San Diego stocks generally remained in their own lackluster level, although some stocks managed to show some good gains, Katz said.

The three stocks that made new highs were PS Group, Gensia Pharmaceuticals and Mail Boxes Etc. The best gainer of the week was Xytronyx, which gained $4 to close at $19.50 after FDA approval to export a periodontal tissue monitor kit.

Other good gains last week included Burnham Pacific Properties, up $1.50; Molecular Biosystems, up $2.25; Biomagnetic Technologies, up $1.625; Alliance Pharmaceuticals, up $1.75, and Magma Power, up $3.

Price Co. was down $1.50 for the week. The prospectus for its recent convertible debenture offering indicated that its second quarter, which ends this week, will show little or no earnings growth over last year’s second quarter.

Agouron Pharmaceuticals, which in recent weeks had run up from $6 to $11, gave back $2 and closed the week at $7.75, Katz said.
