Unisys Corp was suddenly the most popular stock on the Big Board last week after it reported unexpectedly firm fourth-quarter profits of $80.5m and the shares rose $1.25 to $7 as holders took profits and bulls clamoured to buy, so that nearly 9% of the shares were traded; Tom Willmott, vice-president of research outfit Aberdeen Group, said the profit indicated the confidence of their customer base, that Unisys’ quality products weren’t going to be overcome by the shaky financial situation; we’ve got this positive surprise even without volume shipments of the new mainframes, Martin said, who warned that there would still likely be a return to losses this quarter.
