Here’s Why You Should Invest in All the Sectors, Not Just One


Featured image for “Here’s Why You Should Invest in All the Sectors, Not Just One”

When markets shift unexpectedly, portfolios focused on a single sector can take a hard hit. That’s why diversifying across all sectors, from technology and health care to energy and financials—helps smooth performance and reduce risk over time.

Annual Rankings of Equity Sector Returns 2015–2024

Sectors Move in Waves

  • From 2015 to 2024, no sector was a consistent outperformer.
  • Energy, the best performer in 2016, 2021, and 2022, delivered the worst annual returns five times. Tech, the leader in 2023, finished ninth out of 11 in 2022. Health care finished first in 2015, last in 2016, and first again in 2018.
  • The absence of a reliable pattern in sector performance supports an “own them all” approach.

Balancing Acts for Your Portfolio

Holding stocks across all sectors puts investors in a position to capture higher returns where and when they appear.

  • Risk reduction: If one sector crashes, others may cushion the blow
  • Unpredictable leadership: Historical data shows no reliable pattern; by investing across sectors, you capture potential upside wherever it emerges
  • Leverage long-term trends: Diverse exposure positions you for growth driven by macroeconomic, demographic, or industry cycles
