All of the following are characteristics of multinational companies except:

Multinational companies are defined by their operations across multiple countries, allowing them to take advantage of global market opportunities. They often seek to maximize profits not just within their home country but across all the markets where they operate. Therefore, the statement that they aim to maximize profits only within their home country does not align with the fundamental objectives of multinational enterprises.

In contrast, multinational companies typically operate in multiple national environments, which allows them to diversify their markets and reduce their dependence on any one country's economy. They maintain a single head office in their home country for overarching strategic direction but employ various strategies tailored to local markets, enhancing their adaptability and effectiveness. Additionally, one of their primary strategies for growth involves expanding into foreign markets, thereby broadening their market reach and increasing potential profits on a global scale.

The correct assertion, that they aim solely at profits within their home country, contradicts the very nature of what defines a multinational company.
