Also in the Wall Street wars yesterday was Digital Equipment Corp, whose shares were briefly suspended because there were too many sellers after Merrill Lynch & Co analyst George Elling reduced his earnings estimates for the fiscal second quarter to the end of 1991 to a range of 25 to 30 cents a share from his previous estimate of 50 cents – against 92 cents a share in the year-ago quarter; he has also cut his 1992 fiscal year estimate to $3.25 a share from his previous range of $3.75 to $4 a share – DEC did $3.17 a share after charges in its fiscal 1991 to June 30 last; the shares were off $2.25 at $60.75 in mid-morning trading in New York; by 12.30pm New York time, the Dow Jones Industrial Index, off 25 earlier, had recovered 11 of that.
