@Pauli_Lohi har skrivit en utmärkt artikel om köplägen i kvalitetsbolag, med “exemplen” Vaisala och Hexagon. 
How do you find good buying opportunities in growing quality companies such as Vaisala and Hexagon, which almost always look expensive relative to their near-term performance? We believe these companies should be bought when the market fears the short-term effects of a weak demand cycle - in other words, a dip. Stock prices tend to rise too much when economic booms are prolonged and fall too much when the near-term outlook weakens. We compared the historical stock returns of Vaisala and Hexagon against historical valuation levels, which makes Hexagon in particular look like an interesting stock pick at the moment.
