  ## Publications
  
  What I Learned This Week (WILTW) is 13D Research's flagship publication. WILTW began as an English-language international weekly newsletter in 2001, although today the newsletter is also published in Mandarin Chinese. The newsletter developed a global following of institutional investors, political leaders, and corporate executives. The publication covers a wide range of investing themes, including commodities, currencies, central bank policies, technology, demographics, political and social trends, energy markets, food security, credit markets, cyber security, climate change, and country-specific analyses of China, Japan, India, et al. It also covers a breadth of topics outside of the financial sector, such as literature, history, and personal health.
