Are Exchange-Traded Funds (ETFs) less safe than regular mutual funds?
I wonder if ETF's are further removed from the actual underlying holdings or assets giving value to the fund, as compared to regular mutual funds. Not exactly removed. But slightly different. Whenever a Fund want to launch an ETF, it would buy the underlying shares; create units. Lets say it purchased 10 of A, 20 of B and 25 of C. And created 100 units for price x. As part of listing, the ETF company will keep the purchased shares of A,B,C with a custodian. Only then it is allowed to sell the 100 units into the market. Once created, units are bought or sold like regular stock. In case the demand is huge, more units are created and the underlying shares kept with custodian.  So, for instance, would VTI and Total Stock Market Index Admiral Shares be equally anchored to the underlying shares of the companies within the index? Yes they are. Are they both connected? Yes to an extent. The way Vanguard is managing this is given a Index [Investment Objective]; it is further splitting the common set of assets into different class. Read more at Share Class. The Portfolio & Management gives out the assets per share class. So Vanguard Total Stock Market Index is a common pool that has VTI ETF, Admiral and Investor Share and possibly Institutional share. Is VTI more of a "derivative"? No it is not a derivative. It is a Mutual Fund.
