The Dow Jones Industrial Average continues on...

The Dow Jones Industrial Average continues on its merry way to new high after new high, but the broadly based averages have yet to catch up, said Irving Katz, director of research at Thomas Green/San Diego Securities.

“Only four of the 61 stocks that we chart managed new highs last week, and there was one new low,” Katz said.

Synbiotics, which went public in 1983 at an adjusted price of $5 and which reached a high of $15.75 in 1987, was the stand-out low. The company recently reported a loss of 83 cents ar share for the fiscal year ended March 31, versus a loss of 79 cents a share for the previous year. Revenues increased moderately to $8.6 million from $7.3 million.

On the brighter side, Cohu made a new high during the week of $12.75 and closed Monday at $12.375, up $1 for the day, on a favorable mention in the lastest issue of Barron’s financial weekly. Mycogen made a new high of $18.75 but closed the week at $17.50. On April 27, the company filed for permission to sell stock at a public offering totaling 1.7 million shares.

The third new high was La Jolla Bancorp at $14.375. The company’s stock will be exchanged for $15 worth of Security Pacific stock when the merger is completed in late July. Rounding out the list of new highs was Christiana at $13.50, although there have been no recent news announcements to account for the move.

The best point mover of the week was Price Co., which was a case, to use Yogi Berra’s phrase, of deja vu all over again. Price Co. stock, which had recently climbed from $33.50 to $39.25 before retreating back to $35.50, rebounded $3.75 to close the week at $39.25 again.

The best percentage gainer was Great American Bank, which climbed from $2.25 to a high of $3.50 per share before closing on Monday at $3, a 33% gain.

The largest point loser of the week was Xytronyx, which fell $3.25 in continued reaction to a negative analysis by Barron’s Editor Alan Abelson in his column a week ago. Xytronyx, whose low for the year was $6.50, had recently made a new high of $22.625.

Intermark, which closed the week unchanged at $7, reported a fiscal 1990 loss of $1.20 a share versus a $.03 loss per share for the previous year.
