The stock market appears to be broadening, with participation increasing beyond the dominant megacap tech and energy sectors. Recent chart analysis suggests a potential shift away from mega-cap leadership, indicating a more widespread bull market.
Investors should consider diversifying their portfolios to capture potential gains from sectors beyond the largest technology and energy companies, as market breadth expands.
As August winds down, a period traditionally marked by investor caution due to the 'summer doldrums,' it's crucial to discern meaningful market movements from seasonal noise. Last year, a brief dip in U.S. bond yields and the dollar/yen pair, triggered by weaker nonfarm payrolls, ultimately amounted to little. This serves as a reminder not to overreact to conflicting market signals.
While discussions about rising rates, U.S. deficit challenges, and inflationary pressures persist, recent inflation readings do not yet justify the start of a tightening cycle. Charts indicate a recent uptick in the iShares value/growth and Vanguard value/growth ratios, coinciding with the U.S. 10-year Treasury yield pressing against its upper range. However, this move in rates may not be the sole driver for a rotation from growth to value.
To illustrate the market's current complexity, consider the year-to-date sector performance. Energy and technology have vied for leadership, with energy briefly taking the lead with a 42% year-to-date gain compared to tech's 29%. However, the broader S&P 500's gain of approximately 13% is surrounded by other sectors clustered more closely around this benchmark. This suggests the ongoing secular bull market is not threatened by higher rates or a significant rotation out of growth stocks.
Participation in this bull market is becoming more widespread, with leading equities emerging from sectors beyond just tech and energy. While energy constitutes about 3.5% of the S&P 500's weighting and technology around 38%, energy's contribution to overall S&P 500 gains is limited due to its smaller market capitalization. Conversely, technology has been responsible for approximately 80% of the S&P 500's gains this year. This dynamic may be shifting.
Three key ratio charts illustrate this evolving trend:
- S&P 500 Market Cap Weighted vs. Equal Weighted Ratio (SPY/RSP): This ratio double-topped in Q4 2025 and Q2 2026 and is now testing its 2023 uptrend line.
- Invesco QQQ Trust vs. First Trust Nasdaq-100 Select Equal Weight ETF (QQQ/QQEW): The uptrend on this ratio has been broken, mirroring the SPY/RSP trend.
- Roundhill Magnificent Seven ETF vs. Equal Weight QQEW (MAGS/QQEW): A declining ratio here indicates the Magnificent Seven (MAGS) is weakening relative to the equal-weighted Nasdaq-100 (QQEW). This implies that QQEW is either outperforming MAGS during a rally or declining less severely during a sell-off.
Taken together, these charts suggest that mega and large-cap stocks are no longer the sole leaders of this bull market. Savvy active investors should consider gaining exposure to sub-megacap names. At Inside Edge Capital, we have increased our weighting in energy to 2x in our growth portfolio and nearly 3x in our equity income portfolio. As we rebalance and reallocate for investors to provide alpha, we are looking beyond the Magnificent Seven and hyperscalers to identify fundamental and technical leaders across the other nine S&P 500 sectors.
