Strategic Allocation

We have updated monthly allocations and performance data for the Simple Asset Class ETF Momentum Strategy (SACEMS) and the Simple Asset Class ETF Value Strategy (SACEVS). We have also updated performance data for the Combined Value-Momentum Strategy.

Very unusually, the different between SACEMS ranks 2 and 3 is within the range of post-close ETF adjustments. If these adjustments change the ranks, we will make the changes to SACEMS for consistency with historical backtest.

We have updated the Trading Calendar to incorporate data for August 2024.

The home page, Simple Asset Class ETF Momentum Strategy (SACEMS) and Simple Asset Class ETF Value Strategy (SACEVS) now show preliminary positions for September 2024. SACEMS rankings for positions two through four are very close and could change by the close. SACEVS allocations are unlikely to change by the close.

“SACEVS and SACEMS Strategy Momentum?” finds support for belief that a strategy exploiting the relative performance of Simple Asset Class ETF Value Strategy (SACEVS) Best Value and Simple Asset Class ETF Momentum Strategy (SACEMS) Equal-Weighted (EW) Top 2 boosts performance, with focus on a 60%-40% tilt toward the strategy with the stronger past returns. It also considers a full tilt (100%-0%) toward the stronger strategy for one lookback interval. Here, we examine sensitivity of the performance of the full tilt alternative (SACEVS-SACEMS Momentum) across lookback intervals ranging from one to 12 months. This alternative holds either SACEVS Best Value or SACEMS EW Top 2 according to which has the higher past return. We focus on gross compound annual growth rate (CAGR) and gross maximum drawdown (MaxDD) as essential performance metrics. As a benchmark, we use the monthly rebalanced SACEVS Best Value-SACEMS EW Top 2 50%-50% baseline (SACEVS-SACEMS 50-50 Baseline). Using monthly returns for SACEVS Best Value and SACEMS EW Top 2 during July 2006 through July 2024, we find that:

Do alternative “Cash” (deemed risk-free) instruments materially affect performance of the “Simple Asset Class ETF Momentum Strategy” (SACEMS)? Changing the proxy for Cash can affect how often the model selects Cash, as well as the return on Cash when selected. To investigate, we test separately each of the following yield and exchange-traded funds (ETF) as the risk-free asset:

• 3-month Treasury bills (Cash), a proxy for the money market as in base SACEMS
• SPDR Bloomberg Barclays 1-3 Month T-Bill (BIL)
• iShares 1-3 Year Treasury Bond (SHY)
• iShares 7-10 Year Treasury Bond (IEF)
• Vanguard Short-Term Inflation-Protected Securities Index Fund (VTIP)
• iShares TIPS Bond (TIP)

We focus on compound annual growth rate (CAGR) and maximum drawdown (MaxDD) as key performance metrics and consider Top 1, equally weighted (EW) EW Top 2 and EW Top 3 SACEMS portfolios. Using end-of-month total (dividend-adjusted) returns for the specified assets during February 2006 (except May 2007 for BIL and October 2012 for VTIP) through July 2024, we find that:

Are the “Simple Asset Class ETF Value Strategy” (SACEVS) and the “Simple Asset Class ETF Momentum Strategy” (SACEMS) mutually diversifying. To check, based on feedback from subscribers about combinations of interest, we look at three equal-weighted (50-50) combinations of the two strategies, rebalanced monthly:

1. 50-50 Best Value – EW Top 2: SACEVS Best Value paired with SACEMS Equally Weighted (EW) Top 2 (aggressive value and somewhat aggressive momentum).
2. 50-50 Best Value – EW Top 3: SACEVS Best Value paired with SACEMS EW Top 3 (aggressive value and diversified momentum).
3. 50-50 Weighted – EW Top 3: SACEVS Weighted paired with SACEMS EW Top 3 (diversified value and diversified momentum).

We consider as a benchmark a simple technical strategy (SPY:SMA10) that holds SPDR S&P 500 ETF Trust (SPY) when the S&P 500 Index is above its 10-month simple moving average and 3-month U.S. Treasury bills (Cash, or T-bills) when below. We also test sensitivity of results to deviating from equal SACEVS-SACEMS weights. Using monthly gross returns for SACEVS, SACEMS, SPY and T-bills during July 2006 through July 2024, we find that: Keep Reading

A subscriber observed and asked: “Many Bogleheads at Vanguard prefer a buy and hold portfolio of 50% SPY, 25% each BND and EFA [rebalanced annually]. How does this compare to your current strategy? And how does it compare to buy and hold QQQ?” To compare, we compute gross monthly returns for the following six strategies:

1. SPY-EFA-BND Portfolio: the specified combination of SPDR S&P 500 ETF Trust (SPY), iShares MSCI EAFE ETF (EFA) and Vanguard Total Bond Market Index Fund (BND), rebalanced at the end of each June.
2. Simple Asset Class ETF Value Strategy (SACEVS) Best Value: the best SACEVS asset, reselected monthly.
3. SACEVS Weighted: the weighted combination of undervalued SACEVS assets, rebalanced monthly (probably the most closely related to SPY-EFA-BND Portfolio)..
4. Simple Asset Class ETF Momentum Strategy (SACEMS) EW Top 2: the equal-weighted combination of the top two SACEMS assets, reformed monthly.
5. Best Value – EW Top 2: the monthly rebalanced combination of 50% SACEVS Best Value and 50% SACEMS EW Top 2.
6. Buy-and-hold QQQ: buy and hold Invesco QQQ Trust (QQQ).

We focus on compound annual growth rate (CAGR) and maximum drawdown (MaxDD) as essential performance statistics. Using monthly dividend-adjusted prices for SPY, EFA, BND and QQQ and monthly gross returns for SACEVS and SACEMS during April 2007 (limited by inception of BND) through June 2024, we find that: Keep Reading

A subscriber requested evaluation of versions of the Simple Asset Class ETF Value Strategy (SACEVS), the Simple Asset Class ETF Momentum Strategy (SACEMS) and a combination of the two, as follows:

1. For SACEVS Best Value, which chooses the asset proxy for the term, credit or equity premium that is most undervalued (if any), use only every third signal rather than every monthly signal. We start these quarterly signals with the first available signal in July 2002.
2. For SACEMS Equal-Weighted (EW) Top 2, use only every third signal rather than every monthly signal, rebalancing to equal weights only with these quarterly signals. We align quarterly signals with those for SACEVS.
3. For the SACEVS-SACEMS combination, use 30%-70% weights (per “SACEVS-SACEMS for Value-Momentum Diversification”) and rebalance only quarterly. We align quarterly rebalancings with those for SACEVS.

The overall approach is to suppress trading by limiting portfolio reformations/rebalancings to quarterly, while retaining the informativeness of monthly inputs. We apply these changes and compare results to those for the tracked (baseline) versions of SACEVS Best Value, SACEMS EW Top 2 and their 50%-50% combination. Using monthly SACEMS and SACEVS data during July 2006 (limited by availability of a commodities proxy in SACEMS) through June 2024, we find that: Keep Reading

The four iShares Core Asset Allocation exchange-traded funds (ETF) offer exposures to U.S. stocks, global stocks and bonds semiannually rebalanced to fixed weights, as follows.

1. iShares Core Conservative Allocation (AOK) – 30% stocks and 70% bonds (30-70).
2. iShares Core Moderate Allocation (AOM) – 40% stocks and 60% bonds (40-60).
3. iShares Core Growth Allocation (AOR) – 60% stocks and 40% bonds (60-40).
4. iShares Core Aggressive Allocation (AOA) – 80% stocks and 20% bonds (80-20).

Each fund holds a portfolio of seven iShares Core stocks and bonds ETFs, thereby compounding management costs and fees. Do these funds of funds offer attractive performance? To investigate, we compare performance statistics for these funds with those for comparably weighted and rebalanced combinations of SPDR S&P 500 Trust (SPY) and iShares 20+ Year Treasury Bond (TLT), or SPY and iShares iBoxx $ Investment Grade Corporate Bond (LQD). We start tests at the end of December 2008 (about a month after inception of the asset allocation ETFs). We ignore semiannual rebalancing frictions for the SPY-TLT and SPY-LQD comparison strategies. Using semiannual dividend-adjusted prices for all specified funds during December 2008 through June 2024, we find that: Keep Reading

Are all of the potentially trending/diversifying asset class proxies used in the Simple Asset Class ETF Momentum Strategy (SACEMS) necessary? Might one or more of them actually be harmful to performance? To investigate, we each month rank the nine SACEMS assets based on past return with one excluded (nine separate test series) and reform the Top 1, equally weighted (EW) Top 2 and EW Top 3 SACEMS portfolios.
