Why defence has become a key sector for the markets
The shift is not only geopolitical: it is financial as well. In just a few years, defence and aerospace companies have ceased to be seen as peripheral stocks, tied solely to public spending, and have instead become a sector attracting growing interest from global investors. This transformation is being driven by rising military expenditure, competitive industrial margins, solid dividend policies, and a demand for security that is set to remain high. The result is a profound change in the way capital interprets the relationship between defence, industry, and development.
