Co-branding has become a vital strategy in the fashion marketing industry. The strategy involves collaborating with other brands to jointly innovate new products. This paper looks at the positive and negative aspects of co-branding. Taking the co-branding initiatives by Gucci as a case study, this paper makes the following findings. Co-branding helps brands to grow as long as both the two collaborating brands have unique strengths that make them better together. Such strengths may include market reach, brand awareness and reputation, and technical know-how. However, co-branding may produce unintended negative consequences when one brand suffers a negative brand image, which ends up getting transferred to the co-branding partner. Furthermore, either of the collaborating brands may lose its original brand image due to the influence of the partner brand. In the case of Gucci, it is found that the co-branding initiatives have resulted in mutual benefits for Gucci and its partners, but the strategy should not be extended for a long duration, as this is a risk factor for brand dilution.

For a long time, both nationally and internationally, RMB hedging has been a contentious issue. The study and analysis of triangle and quadrilateral hedging in 30 countries are the focus of this article. In addition, they are classified into three groups: industrialized nations, developing countries, and backward countries, with the 30 countries that were chosen falling into each category. On the other hand, triangular arbitrage is an arbitrage that benefits from cross-exchange rate price movements. In contrast, quadrilateral arbitrage follows in the footsteps of those above but involves going via two more countries. Moreover, the data analysis for triangular and quadrangle arbitrage uses the total average, average, maximum, and minimum of favorable spreads, per the study below. From all of this, it could be seen that square hedging frequently has a broader spread or more losses, while triangular hedging frequently has a narrower spread.
