Questions people ask
What are the top holdings of QTUM?
Its filing lists 86 stock positions. The largest are ARQIT QUANTUM INC 2.4%, HQ 2.4%, QNT 1.6%, and the ten largest together are 16.9% of the fund. The full list with weights is on this page.
How often do these holdings change?
Funds report their positions to the SEC at each quarter end, and the SEC publishes the filing about 60 days later. Ploutos reads the latest one every week, so the page changes four times a year, and shows the date of the filing it reads.
Why does the coverage not reach 100%?
The list is the stock positions the fund reports. Cash, futures, bonds and other assets the filing carries are not listed, and what the stocks add up to is the coverage shown. A stock fund lands near 100; a fund that holds futures or a cash sleeve lands lower. Weights are of the whole fund.
