There is strong evidence that investors around the world favour their home market and this is reflected in their portfolio holdings. The phenomenon is known as home bias and has remained a puzzle in academic literature for decades.
Despite barriers to international investment continuing to fall, most individual investors have remained overly invested in their domestic market.
