Want $1 Million in Retirement? 9 ETFs to Buy Now and Hold for Decades.

If you want to amass a million dollars (or more!) by retirement, the stock market is arguably your best long-term investing approach. There are lots of ways to invest in the stock market, though. For example, you can do quite well just plunking significant sums into a simple, low-fee index fund, such as one that tracks the S&P 500. The S&P 500 has averaged annual returns close to 10% (ignoring inflation) over long periods.

To aim for better returns than that, you might add lots of carefully chosen individual stocks to your portfolio. Alternatively, you might want to consider sector exchange-traded funds (ETFs) for sectors you're bullish on.

What are Sector ETFs?

The business world can be divided into 11 sectors (groups of stocks with multiple commonalities, usually because they are in similar industries). Some sectors will perform better than others over any given period. As you decide on an ETF, think about which sectors seem most promising to you. Once you have a few in mind, look for ETFs with low fees and good track records that specialize in those sectors.

An ETF is very much like a mutual fund, filled with a variety of securities and invested in by many shareholders. But it trades like a stock, not a fund, so you can buy a few or a lot of shares whenever the stock market is open through your regular brokerage account.

Here are nine sector ETFs to learn more about and consider. Each might turbocharge your portfolio -- though none is guaranteed to do so, of course. You might compare each one's returns with those of a low-fee S&P 500 index fund like the Vanguard S&P 500 ETF (VOO 1.00%), which is at the top of the chart below.

Remember, though, that an ETF with an 11% 10-year average annual return might average far less or much more than that over the coming decade. Past performance is not a certain indicator of future performance. Think more about your expectations for each sector and then look closely at ETFs of interest, seeing what stocks constitute their portfolios and what expense ratios (annual fees) they charge.
