Not sure anyone read the Vanguard's paper published last year on international equity and home bias.
This paper?
That's not the conclusion drawn by the authors.
In light of our quantitative analysis and qualitative considerations, we have demonstrated that domestic investors should consider allocating part of their portfolios to international equities. In determining how much to allocate between domestic and international equities, a helpful starting point for investors is global market-capitalization weight.
Singapore's data was not in Figure 2. The paper compared 4 other countries in Figure 3. Our market cap weight is really a tiny dot compared to the world's.
