The following are some interesting points for advertisers and sponsors of the Olympic based on research papers in https://www.academia.edu

1. Olympic Advertisers Outperforming the S&P 500 Index:

- A study found that Olympic advertisers tend to outperform the S&P 500 Index in the four-week window around the Games. This suggests that being associated with the Olympics can positively impact stock performance.

2. Specific Companies as Olympic Sponsors:

- Some companies have been long-standing Olympic sponsors. For instance:

- Coca-Cola: Their century-long partnership with the Olympic Games has been successful. They often release limited-edition products and packaging to celebrate the Games.

- Cisco Systems, Panasonic, etc: These companies have been involved in various capacities as Olympic sponsors, providing technology, construction services, and support.

3. Domestic vs. Foreign Sponsors:

- Research shows that Olympic sponsorship announcements impact stock returns differently for domestic versus foreign sponsors. Abnormal returns are significantly higher for firms domiciled in the host country compared to those outside the host country. Olympic partners (who pay higher sponsorship fees) also experience higher returns than Olympic supporters.

In summary, Olympic sponsorship can be a value-creating strategy, especially for domestic firms. The impact varies based on factors like sponsorship type, company size, and market dynamics.
