How do growth ETFs work?
A growth ETF is a fund that invests in a portfolio of stocks. It's managed by a fund manager, and investors can buy shares of the fund via a stock exchange, just as they'd buy a regular stock.
The stocks in a growth ETF could be actively managed or passively managed. If actively managed, the fund manager is making decisions on which stocks to buy, sell, and hold in the fund's portfolio. If passively managed, the fund will track a benchmark index designed to represent growth stocks.
When an ETF experiences capital inflows or outflows, it relies on large financial institutions, called authorized participants, to create or redeem shares. They buy or sell the fund's individual components on the open market to ensure the right number of ETF shares is available.
Growth versus value ETFs
Growth ETFs can be much more volatile than value stock ETFs. Value stocks are generally more stable. Revenue and earnings are more predictable, and changes in outlooks don't move the stocks nearly as much. As a result, investors can expect a smoother ride from value ETFs than from growth ETFs.
Growth ETFs offer the possibility of outperformance in exchange for greater volatility, making them suitable for long-term investors willing to hold their shares for years.
Benefits and risks of investing in growth ETFs
There are quite a few benefits to buying a single growth ETF for your portfolio:
- They provide instant diversification across multiple businesses, reducing the risk relative to investing in just a handful of growth stocks.
- You gain exposure to the major growth trends without having to research or discover them yourself.
- The fees are relatively small, especially if you choose an index fund instead of an actively managed mutual fund.
There are some important risks to consider, though.
- Growth ETFs exhibit greater volatility than the overall market or value ETFs.
- You might not be as diversified as you think, since many growth ETFs are highly concentrated in specific sectors, such as technology.
- Some ETFs that don't fully replicate their index could exhibit greater tracking error than other indexes, leading to results that don't match the index they're meant to track.
