Stocks continued their lackluster performance last week with the uncertainties of recession, war, inflation and deflation casting ominous clouds over the market, according to Irving Katz, director of research for Thomas Green/San Diego Securities.

San Diego stocks--which did not participate as the Dow Jones Industrial Average soared toward 3,000 this past summer--are, however, joining an overall downward trend with most selling at or near their lows for 1990.

A handful of stocks did manage to make good gains during the past week.

The largest percentage gainer of the week was Charthouse Enterprises, up 21%, following a favorable forecast that was presented at a meeting of analysts and money managers last week in San Francisco.

PS Group was up $2.25 on Monday on the announcement that Warren Buffett of Berkshire Hathaway fame had won permission to increase his affiliate holdings in excess of 20%. PS Group’s board agreed to modify a stockholder rights package that clears the way for the purchase.

Molecular Biosystems gained $.50 on Monday as it announced the submission of a pre-marketing approval application to the U.S. Food and Drug Administration for Albunex, its ultrasound imaging agent. The submission followed 2 1/2 years of testing in the United States, Europe and Japan.

The week, however, had some major casualties. Intermark, a $2-billion holding company with interests in 14 companies, made a new low of $3, down from its 1990 high of $10.75. Since its recent merger with majority-owned Triton Group Ltd., whose shareholders received 1.4 shares of Intermark for each Triton share, the stock has dropped from $5 to $3. The stock has now dropped 40% in less than a month.

Cubic was down $.75 this past week as it announced the phasing out of operations of its communications subsidiary in Oceanside and a layoff of up to 85 people

Besides Intermark, the only other new low registered was Beeba’s Creations at $5.
