Computer software and services deals increased.

The number of mergers and acquisitions involving companies in computer software and services rose to a record 130 in the first half of 1986, up 58% from a year earlier, according to Broadview Associates, an investment banking firm. The value of those transactions more than doubled to $1.9 billion from $846 million, Broadview said. One factor in the hot pace of acquisitions is that many companies in the field have been lagging behind the overall rise in the stock market, making them inexpensive targets.
