Fundamental factors such as low inflation, low interest rates and prospects for higher earnings may be some of the reasons for the market’s strong showing this year, but the violent swings are caused by the emotions of greed and fear, according to Irving Katz, director of research at San Diego Securities.

Profit-taking was the order of the day for most San Diego stocks last week, as the losers were those stocks that had risen the most this month, Katz said.

Among these were Intermark, down 1 1/2; WD-40, down 2; Beeba’s Creations, down 2 3/4, and IRT Corp., down three-fourths despite announcing a new president.

Most other San Diego stocks were down fractionally, Katz said.

On the upside, good earnings reports brought a 1 1/2-point increase to Great American First Savings Bank, which also reported a 50% dividend increase to 15 cents per share.

Imperial Corp. of America was up just one-fourth, despite reporting earnings of $3.55 per share for the year.

San Diego Gas & Electric rose one-fourth, despite an optimistic forecast last week by Chairman Thomas Page that some major utility dividends in a few years will be paid out at a rate of 80% of earnings. SDG&E; is now paying dividends at the rate of 67% of earnings, but the utility, as it has done in recent years, expects to raise its dividend in May.

Christiana Cos. was the big mover of the week, as it rose seven-eighths to close at 6 on the announcement that a Milwaukee investment group had bought 24% of the stock at an average price of 6 3/8 per share.

La Jolla Bancorp made a new high of 6 5/8 after announcing earnings up more than 50% and a 5% stock dividend.

Decom Systems rose five-eighths to 3 1/2 as its annual report showed earings of 34 cents per share, thanks primarily to its growing aerospace system and the elimination of the land mobile radio operation.

Mission West Properties appears to be selling down 1 7/8 for the week, but that’s without the $2 special dividend declared from the sale of the company’s Del Mar property.

International Totalizator rose one-quarter as it announced additional contracts.

Northview Corp., controlled by Ivan Boesky’s wife, Seema, as majority stockholder, rose a point. The trading included a 100,000-share block of stock.

Syntro Corp. rose one-quarter on the receipt of new National Institutes of Health funding for one of its syphilis diagnostic tests.

Fabulous Inns of America was unchanged despite news that a Superior Court judge may place the company in receivership.
