Tracks the Nasdaq-100 index less the 0.48% Management fee.  This index is the top 100 non financial companies listed on the NASDAQ.  Think Google, Amazon, Apple, TESLA etc  through to small holdings in things like Peloton, Netease. 

It does have a big focus on the bigger companies as it is market weighted so Apple, Microsoft, Amazon, Google and Facebook make up about 41% of the index. 

I use this as an easy way to get access to the US technology sector without the need for direct investment and without the pesky W-8BEN form some ETFs require for US tax purposes.  I also prefer it to the FANG funds as while 41% is FANGY like companies, you still get exposure to the next big things.

There may be cheaper ways to do this than this fund but have not researched of late.
