IPKW is an international twist on the issuers US-based buyback fund PKW. IPKW invests in companies included in the NASDAQ Global Ex-US Index (base index) that have recently repurchased significant amounts of their own shares, subject to liquidity and market cap constraints. The concept is straightforward: Management has the greatest insight as to future business prospects so, when they elect to buy back their own stock, it's because they see it as undervalued. The counterargument is that buybacks are indicative of a lack of future growth opportunities, otherwise the company would invest its cash in those prospects. The Index is reconstituted annually in July and rebalanced quarterly starting January.
