Questions people ask
What are the top holdings of IYZ?
Its filing lists 22 stock positions. The largest are CSCO 22.6%, ANET 11.0%, VZ 11.0%, and the ten largest together are 69.5% of the fund. The full list with weights is on this page.
How many stocks are in IYZ?
IYZ reports 22 stock positions in its SEC filing of Jun 30, 2026, and together they are 100% of the fund. Cash, futures and bonds the fund holds are not counted.
How do I check whether IYZ holds a particular stock?
Search the full list on this page by ticker or company name, for example NVDA or Nvidia. A stock the fund holds shows with its weight and its rank in the fund. If it does not show, the fund did not report it as a position in this filing.
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.
