Investment bank Öhman was founded in 1906 by Emric Öhman (1863 - 1934). He was previously part owner of the family-owned grain business but left this in order to start his new business. Öhman became a member of the Stockholm Stock Exchange in 1911 and started trading in equities.
During the 1920s, the company led a fairly quiet life but in 1929 Öhman began to publish a market newsletter for its customers. The comments were typewritten on a single sheet of paper and covered broadly the same topics as today´s newsletters.
When Emric Öhman died in 1934 and his son decided not to succeed him, the firm was taken over by Max Dinkelspiel, who had been employed at the firm since the beginning of the 1930s. Max Dinkelspiel incorporated the company in 1936 and at the same time became Managing Director, a position he held until 1969 after which he was chairman of the company until 1980.
During his student years at the Stockholm School of Economics and INSEAD, Claes Dinkelspiel became interested in measuring company profits and it was during this time that he laid the foundations of what later became Öhman´s Stock Market Guide. The first guide was published in 1966 and with the foundation of Öhman Investment Consultants in 1969, Öhman´s research business took off in earnest.
In the 1950s and 60s, Max Dinkelspiel´s sons Ulf and Claes started employment in the company. However, Ulf Dinkelspiel soon left to join the Ministry of Foreign Affairs, while Claes Dinkelspiel became Managing Director in 1969.
