The BOJ first started their buying spree in December 2010 – when they held no ETFs at all – and have since accumulated some $150 billion in aggregate holdings. The buying was all as part of unprecedented “economic stimulus” which has undoubtedly contributed to the Nikkei 225 Stock Average surging roughly 125% since December 2010.
