During its latest rebalance, the Invesco S&P 500 Momentum ETF (SPMO) halved its exposure to the tech sector from 36.6% to 17.2%, and more than doubled the weight in health care to 27.9%. Utilities and real estate went from nearly zero to 11.7% and 7.1% of the portfolios, respectively. That helps explain the fund’s moderate loss of 1.7% in May, even though the tech stocks within the S&P 500 slumped a much steeper 5.7%.
Few professional investment managers make use of momentum investing, believing that individual stock picking based on an analysis of discounted cash flows and other fundamental factors tends to produce more predictable results, and is a better means of beating index performance over the long term. "As an investment strategy, it’s a thumb in the eye of the 'efficient market hypothesis' (EMH), one of the central tenets of modern finance," to quote a UCLA Anderson Review article, "Momentum Investing: It Works, But Why?" published on Oct. 31, 2018.
Investors should consider the investment objectives and unique risk profile of Exchange Traded Funds (ETFs) carefully before investing. ETFs are subject to risks similar to those of other diversified portfolios. Leveraged and Inverse ETFs may not be suitable for all investors and may increase exposure to volatility through the use of leverage, short sales of securities, derivatives and other complex investment strategies.
How much money do I need to start investing in stocks? The amount of money you need to buy an individual stock depends on how expensive the shares are. (Share prices can range from just a few dollars to a few thousand dollars.) If you want mutual funds and have a small budget, an exchange-traded fund (ETF) may be your best bet. Mutual funds often have minimums of $1,000 or more, but ETFs trade like a stock, which means you purchase them for a share price — in some cases, less than $100).
How much money should I invest in stocks? If you’re investing through funds — have we mentioned this is our preference? — you can allocate a fairly large portion of your portfolio toward stock funds, especially if you have a long time horizon. A 30-year-old investing for retirement might have 80% of his or her portfolio in stock funds; the rest would be in bond funds. Individual stocks are another story. We’d recommend keeping these to 10% or less of your investment portfolio.

Momentum investing usually involves a strict set of rules based on technical indicators that dictate market entry and exit points for particular securities. Momentum investors sometimes use two longer-term moving averages, one a bit shorter than the other, for trading signals. Some use 50-day and 200-day moving averages, for example. The 50-day crossing above the 200-day creates a buy signal. A 50-day crossing back below the 200-day creates a sell signal. A few momentum investors prefer to use even longer-term moving averages for signaling purposes.
