Moving Averages of the Ivy Portfolio and S&P 500: June 2026

1. The Ivy Portfolio 10-month simple moving average shifted to a single invest position after the IEF bond ETF closed below.
2. The S&P 500 lost 1.1% in June, ending its two-month winning streak despite remaining above major moving averages.
3. The S&P 500 closed June 7.3% above its 10-month simple moving average, maintaining an invest position for three months.

The Ivy Portfolio is based on the asset allocation strategy used by endowment funds from Harvard and Yale. It is an equally weighted portfolio constructed with 5 ETFs that feature a mix of different asset classes. By allocating across different asset classes, diversification is achieved, and risk is reduced. The different asset classes and their corresponding ETFs are below.

1. Domestic stocks, represented by Vanguard Total Stock Market ETF (VTI A)
2. International stocks, represented by Vanguard FTSE All-World ex-US Index Fund (VEU A-)
3. Bonds, represented by iShares 7-10 Year Treasury Bond ETF (IEF B-)
4. Real estate, represented by Vanguard Real Estate ETF (VNQ A)
5. Commodities, represented by Invesco DB Commodity Index Tracking Fund (DBC A-)

The process of using the Ivy Portfolio is quite simple. First, compose a diversified portfolio from each of the major asset classes held in equal weight (see above). Then, compute a moving average of closing prices over the prior 10 months for each fund (or desired time frame). Lastly, observe the portfolio at the end of each month. If a fund closes out the month below the level of its moving average, sell it and hold cash, repurchasing only when it closes back above its moving average at the end of any subsequent month. Similarly, if a fund closes out the month above the moving average, hold it.

The table below details the 10-month simple moving average (SMA) for the five Ivy Portfolio asset classes. As of month-end June, the signal has shifted to a single “invest” position as the iShares 7-10 Year Treasury Bond ETF (IEF B-) closed just below its 10-month SMA.

To assist with trend monitoring, the table also includes the percentage by which each fund sits above or below its moving average. Positions highlighted in yellow indicate a fund is within 2% of its signal, flagging a potential reversal in the coming month.

For a broader perspective, the following table displays the 12-month simple moving average (SMA) signals. As of month-end June, all five Ivy Portfolio ETFs closed above their respective averages. This “no cash” signal is unchanged from May, keeping the entire portfolio in an “invest” position for a third straight month. Similar to the 10-SMA strategy, the iShares 7-10 Year Treasury Bond ETF (IEF) is currently highlighted in yellow, indicating they finished the month within 2% of their moving average, only this time it closed just above.

The S&P 500 closed out June with a monthly loss of 1.1%, ending its two month win streak. But let’s examine the index through the lens of moving averages.

Buying and selling based on a moving average of monthly closes can be an effective strategy for managing the risk of severe loss from major bear markets. In essence, when the monthly close of the index is above the moving average value, you hold the index. When the index closes below, you move to cash. The disadvantage is that it never gets you out at the top or back in at the bottom. Also, it can produce the occasional whipsaw (short-term buy or sell signal), which was seen most recently in 2020.

Nevertheless, a 10- or 12-month simple moving average (SMA) strategy would have ensured participation in most of the upside price movement since 1995 while dramatically reducing losses. For confirmation, here is a chart of the S&P 500 monthly closes since 1995 with a 10-month SMA. In June, the S&P 500 closed 7.3% above its 10-month SMA, resulting in an ‘invest’ position for the index for a third straight month.

To further demonstrate, the next chart uses the 12-month variant. By using 12-months instead of 10, the moving average becomes slightly less volatile. Still, we can see that this is just as, if not more, effective in reducing losses. In June, the S&P 500 closed 8.9% above its 12-month SMA, marking its fourteenth consecutive ‘invest’ position.

The next chart uses one more variation to the moving average strategy. The chart shows the 10-month exponential moving average (EMA), which is a slight variant to the simple approach used in the previous two charts. This version mathematically increases the weighting of newer data in the 10-month sequence. Since 1995 it has produced fewer whipsaws than the equivalent simple moving average. However, it was one month slower to signal a “sell” after the two market tops in 2000 and 2007. In June, the S&P 500 closed 7.5% above it’s 10-month EMA, marking a third consecutive ‘invest’ position.

To summarize, all three approaches closed above their respective moving averages and therefore resulted in an ‘invest’ position at the end of June.

A look back at the 10- and 12-month moving averages in the Dow during the Crash of 1929 and Great Depression shows the effectiveness of these strategies during those dangerous times.

Timing works because of a basic human trait. People imitate successful behavior. When they hear of others making money in the market, they buy in. Eventually, the trend reverses. It may be merely the normal expansions and contractions of the business cycle. Sometimes the cause is more dramatic: an asset bubble, a major war, a pandemic, or an unexpected financial shock. When the trend reverses, successful investors sell early. The imitation of success gradually turns the previous buying momentum into selling momentum.

Our illustrations from the S&P 500 are just that — illustrations. We use the S&P 500 because of the extensive historical data that’s readily available and the index signals give a general sense of how U.S. equities are behaving. However, followers of a moving average strategy should make buy/sell decisions on the signals for each specific investment, not a broad index. Even if you’re investing in a fund that tracks the S&P 500 (e.g., Vanguard’s VFINX or the (SPY A-) ETF) the moving average signals for the funds will occasionally differ from the underlying index because of dividend reinvestment. The S&P 500 numbers in our illustrations exclude dividends.

The strategy is most effective in a tax-advantaged account with a low-cost brokerage service. You want the gains for yourself, not your broker or your Uncle Sam.

Valid until the market close on January 31, 2026.

Footnote on calculating monthly moving averages: If you’re making your own calculations of moving averages for dividend-paying stocks or ETFs, you will occasionally get different results if you don’t adjust for dividends. For example, in 2012 VNQ remained invested at the end of November based on adjusted monthly closes, but there was a sell signal if you ignored dividend adjustments. Because the data for earlier months will change when dividends are paid, you must update the data for all the months in the calculation if a dividend was paid since the previous monthly close. This will be the case for any dividend-paying stocks or funds.
