We update today’s table on a regular basis to provide insight into the variability of sector performance by market
capitalization. As of the close on 4/30/24, the S&P 500 Index stood at 5,035.69, 4.16% below its all-time closing high of
5,254.35 set on 3/28/24, according to data from Bloomberg. The S&P MidCap 400 and S&P SmallCap 600 Indices stood
6.08% and 13.51% below their respective all-time highs as of the same date.

  • • Large-cap stocks, as represented by the S&P 500 Index, posted total returns of 6.04% on a year-to-date (YTD) basis
    thru 4/30/24, outperforming the S&P MidCap 400 and S&P SmallCap 600 indices, with total returns of 3.33% and
    -3.30%, respectively, over the period (see table).
    • Sector performance can vary widely by market cap and have a significant impact on overall index returns. Two of the
    more extreme cases in 2023 were the Communication Services and Technology sectors. In 2024, the Communication
    Services, Information Technology, and Utilities sectors all exhibit significant variability in performance across
    market capitalizations.
    • Communication Services and Energy stocks, the two top-performing sectors in the S&P 500 Index YTD, represented
    9.1% and 4.1%, respectively, of the weight of the Index on 4/30/24. By comparison, those sectors represented 1.4%
    and 5.6% of the S&P MidCap 400 Index, and 2.8% and 5.0% of the S&P SmallCap 600 Index, respectively, as of the
    same date.
    • As of the close on 4/30/24, the trailing 12-month price-to-earnings (P/E) ratios of the three indices in today’s table
    were as follows: S&P 500 Index P/E: 24.09; S&P MidCap 400 Index P/E: 18.66; S&P SmallCap 600 Index P/E: 17.92.

Takeaway

As evidenced by the variance in the total return of the Communication Services sector in today’s table, performance can vary widely across market capitalizations. The Utilities and Technology sectors reveal a similar trend, with total returns ranging from 16.04% to -5.87% and 12.07% to -8.61%, respectively. Notably, both the broader S&P 500 and S&P MidCap 400 Indices reached new all-time highs in March 2024, while the record high for the S&P SmallCap 600 Index occurred nearly three and a half years ago on 11/8/21. Combined, the SmallCap and MidCap Indices comprised just 8.1% of the total market capitalization of the S&P 1500 Index as of 4/30/24. The last time (pre-COVID) that small and mid-sized companies accounted for 8.1% or less of the S&P 1500 Index’s market capitalization was on 4/28/00. Since then, the S&P MidCap 400 and S&P SmallCap 600 Indices notched average annual total returns of 9.23% and 9.17% respectively (4/28/00 thru 4/30/24). For comparison, the average annual total return of the S&P 500 Index was 7.32% over the same period. While past performance is no guarantee of future results, it is our opinion that investors with the appropriate time horizons and risk profiles may benefit from exposure to small and mid-sized companies going forward.
