Investors buy and sell ETFs like stocks, typically through a brokerage account.
Investors can also employ traditional stock trading techniques, including stop orders, limit orders, margin purchases, and short sales using ETFs. Margin purchases are subject to SEC approval. As with all stocks, you may be required to deposit more money or securities into your margin account if the equity including the amount attributable to your ETF shares, in your account declines. To preserve the balance between supply and demand for shares of an ETF, large institutions are authorized to create or redeem shares when necessary. This process of creating or redeeming shares requires the authorized institution to contribute or receive in-kind baskets of the underlying stocks to or from the fund.
