Asea and Switzerland's Brown Boveri commenced the discussion of creating a global giant. The two merged in 1986 to create ABB. During the 1980s, Electrolux acquired more than 200 companies. The 1990s were a more difficult time for Electrolux because of heavy debt from the acquisitions and from a recession.

The acquisitions made by STORA, the formation of ABB and the multiple acquisitions made by Electrolux called for expansion of Investor's management. Investor and Providentia grew their staff from 15 to around 60, all of whom are employed by Patricia.

The eventful 1980s included many other developments for Investor: start-ups of a number of companies, and the sale and acquisition of others. One example was the establishment of the stock exchange technologies company OM (OMX today). The new company, whose purpose was to establish a market for trading in standardized options, was a huge success from the start and grew quickly. Today, OMX owns and operates the largest integrated securities marketplace in Northern Europe.
