Johnny同学你好，home bias是familiarity bias在资产配置中的一种体现，也就是说familiarity bias会导致home bias，home bias是familiarity的子集

讲义中说home bias是familiarity with a country may lead investors to own high concentrations of domestic assets. familiarity是employees underestimate risk because of familiarity with the employer and overconfidence.这样看home bias对应的是domestic， familiarity对应的仅仅是employer，感觉familiarity是home bias的真子集？

同学你好，Familiarity with a country may lead investors to own high concentrations of domestic assets. Enthusiasm for own company investment springs from the same familiarity bias that leads to home bias in geographic allocations. The familiarity bias also led US investors to invest more in their local phone company than in other telephone companies.
所以familiarity bias不仅是对本公司也会对于本国，当familiarity体现在本国时就是home bias了
