Although the stock market was buffeted last week by fallout from the Russian nuclear reactor accident and weakness in the bond market, it rebounded Monday on extremely low volume, according to Irving Katz, director of research at San Diego Securities.

San Diego Gas & Electric was down three-quarters for the week, as were most utilities with any nuclear plant involvement. The stock, however, was up three-eighths on Monday as the nuclear cloud seemed to evaporate, Katz quipped.

Great American First Savings Bank was down fractionally after a successful offering of 2.6 million shares.

Investor Victor Goulet finally made his first, $16-million partial payment for Imperial Corp. of America stock, which he had optioned at $15 a share more than two years ago. The $36 million remaining is supposed to be paid before May 15. The stock closed down seven-eighths, at 11 3/8.

Oak Industries successfully completed its exchange offering after much delay. The offering, in which common stock was traded for debentures, allowed Oak to sell its materials division to Allied-Signal. The stock was down one-eighth to 1 1/2.

PSA Inc. was down one-half, to 30, in continued response to its poor first-quarter showing and the calling for redemption of its two outstanding convertible issues.

Handyman was down one-half to 29 3/8 as it held an annual meeting Monday in San Diego--its first since being spun off from Edison Brothers. The company seems to be selling on its real estate value rather than operating earnings, according to Katz, who added that Handyman operates in a very competitive environment and is selling at about 30 times its operating earnings. Real estate sales were responsible for most of last year’s $3.50 in earnings, Katz said.

DeCom Systems was up three-eighths to 3 as it reported earnings of 9 cents a share for the quarter, compared to 1 cent during the same quarter a year ago.

Cousins Home Furnishings was down 1 to 5 1/8 with no earnings reported--and none expected.

Infrasonics units were up three-quarters to 3 3/4 as the company announced the splitting of its units and having the stock and warrants each trade separately effective today.

Kaypro was down one-quarter to 2in continuing response to management’s closed-mouth annual meeting, where officers refused to answer any questions about profitability or shipments, Katz said.

Monitor Labs was down one-quarter to 3 3/4 as newspaper accounts had founder Ed Etess selling his stock and the company reporting that profits would not be likely before the end of the year.

Sym-tek was up 1 to 16 3/4 on reported earnings of 21 cents for the fourth quarter and 92 cents for the year. Sym-tek was one of the few semiconductor-related companies to show any profit last year, Katz observed.

Synbiotics was up 1 point to 14 after registering a 1-million-common-share offering. After the offering, Synbiotics will have 3 million outstanding shares and will remain one of the smaller capitalized biotechnology companies available to investors.
