It's been a roller coaster ride for the stock market over the past few months. After nearly reaching a cycle high in late July, the S&P 500^® suffered a correction of a little more than -10% by the end of October, only to rebound more than 7% since then. It was an even sharper boomerang for the Nasdaq; having a correction of more than -12% between mid-July and the end of October, only to rebound by nearly 10% since then.

The performance table below, which goes on my X (Twitter) feed every day, dives into more detail on the stock market's behavior both year-to-date (YTD), and since last year's October low for the S&P 500. Perhaps most notable are the "average member maximum drawdown" columns for each period. Courtesy of the bias in performance toward a few mega-capitalization (mega-cap) stocks, the significant weakness under the surface of index-level performance has been somewhat masked. In particular, notice that the average Nasdaq member maximum drawdown from YTD highs is nearly -50%.

In terms of sector-level behavior during the correction phase, deep cyclicals and interest-rate-sensitive segments of the market—like Real Estate Investment Trusts (REITs) and Consumer Discretionary—fell the most, while Energy performed the best (but still fell by -3%). Conversely, the sharp rally from the late October low has been led by the "big 3" sectors that house the "Magnificent 7" (Mag7): Technology, Communication Services, and Consumer Discretionary. Within the Technology sector are Apple, Microsoft, and NVIDIA; within the Communication Services sector are Alphabet (Google), and Meta; and within the Consumer Discretionary sector are Amazon and Tesla. Each of the Mag7 weightings with the S&P 500 are shown below.

The performance bias of the Mag7 can be clearly seen in the chart below, covering the period since the early-2022 market top that ushered in last year's bear market. It's a stark reminder that although the Mag7 has been this year's darling group (shown via the ascendency of the yellow line in 2023), they represented the ultimate drag during 2022's bear market; only accelerating sharply relative to the overall S&P 500 and the S&P ex-Mag7 since the beginning of this year.

Although the stocks are often lumped together for analysis, it is the case that they have not behaved as a monolith, as shown below via the maximum drawdowns chart which I put on my X (Twitter) feed every day. They are the seven largest stocks within the S&P 500, but don't confuse size with performance. Yes, they all have strong YTD performance, but their ranking within the index is as follows: NVIDIA-1st, Meta-2nd, Tesla-9th, Amazon-11th, Microsoft-24th, Alphabet-28th, and Apple-33rd.

Specific to this year so far, less than a third of S&P 500 stocks have outperformed the overall index during the past three months. That is above the record low of 19% on June 1 this year, but it has remained below 50% since the end of February. The long-term average of that statistic is just below 50%. (Hat tip Ned Davis Research for the historical stats.)

Our friends at Strategas Research Partners recently wrote an interesting report highlighting what the Mag7's characteristics would be if it were its own sector within the S&P 500. We dive in with some updates here. As shown below, if the Mag7 were its own sector, it would be the largest, at 30% of the overall index. That eclipses the current largest weight associated with the Technology sector.

The Mag7 would not only be the largest sector in terms of weight within the S&P 500 index; when comparing sectors' market cap with net income, it would represent the largest spread, as shown below. In other words, its market cap weight is not "justified" by its net income weight. On the other end of the spectrum are the Financials and Energy sectors, both carrying significantly larger net income weights relative to their market cap weights.

In terms of sector laggards during the rally off the correction lows of late October, Energy takes the prize and is the only sector in negative territory, largely due to the reversal lower in oil prices. One major theme throughout the correction phase was the inability of traditional defensives to work like they are "supposed to" in selloffs. Namely, Utilities and Consumer Staples did not provide any kind of edge, having underperformed the overall S&P 500. We do not believe that's an aberration. Staples have struggled this year as disinflation has dented their pricing power, while Utilities—typically considered bond proxies—have been under increasing pressure from the recent upward move in Treasury yields.

Below is our take on the traditional asset class "quilt," which typically shows broad asset classes ranked by year. Instead, we show all 11 of the S&P 500's sectors, ranked by month over the past year. You can see the extraordinary month-to-month volatility of sector performance—with a glaring example being Energy sitting atop the leaderboard for three consecutive months starting in July, only to find itself at the bottom of the pile in October (also notice that in seven months of the one-year period shown, Energy was either at the very bottom or very top). Even Utilities have bounded a few times from the very top to the very bottom.

It's no coincidence that REITs and Utilities are the two worst-performing sectors over the past year, with both sectors hovering near multi-year lows. It's one reason why we've been emphasizing that the S&P 500's advance since its October 2022 low does not yet look like a strong/durable new bull market. The reality in a higher-for-longer interest environment is that investors may have to leave monolithic mindsets behind. Traditional "defensives" have not provided downside protection to the same degree they have in the past.

For what it's worth, factor performance (based on how stocks screen on certain characteristics) has been more consistent. As most readers know, we have been very focused on factors vs. sectors during this market cycle, with a particular emphasis on quality-oriented factors like high interest coverage, low volatility, and strong free cash flow. Interest coverage has been one of the best-performing factors this year, with less volatility than sector-based performance.

Helping explain interest coverage as a dominant factor in terms of performance is the close connection between bond yields and stock prices—even when muting the impact of the Mag7. Shown below, since the S&P 500 peaked on July 31 this year, the inverse correlation between the S&P Equal Weight index and the 10-year Treasury yield has been nearly perfect (we inverted the 10-year yield so the relationship is clear to see).

Even as bond yields are lower than their recent peak, they continue to hover around the highest level in more than a decade. This has been disruptive for companies that are heavily indebted; especially those which haven't termed out their debt and/or don't have strong enough cash flows to cover rising interest expense. This has put emphasis on sectors like Utilities—which has a low and falling interest coverage ratio—and REITs. For the latter, as shown below, it's the weakest in terms of interest expense as a percentage of revenue. Interestingly, as you can see at the far right in the chart below, if the Mag7 were its own sector, it would have the lowest interest expense as a percentage of revenue. That represents one of the key "fundamental" supports of the group's outperformance this year.

As regular readers of our work know (Say Goodbye…to Great Moderation? | Charles Schwab), we have been highlighting the inverse relationship between bond yields and stock prices as one sign that we are likely transitioning to a different secular backdrop relative to the Great Moderation era from the late 1990s to the start of the pandemic. We believe this new secular era may be somewhat akin to what we've been calling the "Temperamental Era" spanning from the mid-1960s to the late 1990s. During that span, there was a consistent inverse relationship between bond yields and stock prices, when measured on a one-year rolling basis. During the Great Moderation, it was the opposite: nearly the entire period was characterized by a positive correlation. This is clearly shown below.

This week is chock-full of economic data, including the much-anticipated consumer price index (CPI) and producer price index (PPI) inflation reports, retail sales and several key housing-related reports. We're also closing the book on earnings season; but the important messages from many retailers are still in front of us given they typically have a one-month-later fiscal year end. As shown below, third-quarter earnings season has been decent courtesy of a higher-than-average "beat rate," which means the "blended growth rate" (incorporating reports already in the books with estimates for companies not yet having reported) has moved up sharply from only 1% in mid-October to more than 6% as of Friday. However, notice the mirror image move down in estimates for the fourth quarter, from about 11% in late September to less than 6% as of Friday. This is denting the "earnings have put in a bottom" refrain, evident as recently as a month ago.

There have been a few shorter-term "breadth thrusts" during the latest rally, but they haven't yet had a significant impact on longer-term breadth. For the S&P 500, only 50% of its stocks are trading above their 50-day moving averages; while it's only 38% for the Russell 2000 and 34% for the Nasdaq. Relative to their 200-day moving averages, they are 42% for the S&P 500, 30% for the Russell 2000, and 27% for the Nasdaq. In the meantime, although it's been a nice two-week reprieve from the selling during the correction phase, only 5% of the S&P 500's members have made a new 52-week high.

We are hoping to see a broadening out in terms of performance, with less dominance by the Mag7. However, we continue to think leadership (within and beyond the Mag7) will be defined by high quality factors. It's a theme we will address in more detail in our 2024 outlook report being published in a couple of weeks, so stay tuned, stay up in quality, and stay disciplined.
