SPDR S&P Semiconductor ETF (NYSEARCA:XSD) offers equal-weight exposure to the semiconductor sector, a structure that amplifies both opportunity and risk. The fund has gained 43.15% over the past year as AI infrastructure spending supercharged demand for chips across the supply chain. The equal-weight structure - which gives smaller names the same influence as giants - has both amplified those gains and introduced drag from legacy players like Intel that have not kept pace with the AI cycle.
When geopolitical tensions rise or defense budgets expand, investors often chase the sector through broad market funds. But SPDR S&P Aerospace & Defense ETF (NYSEARCA:XAR) doesn't work like most sector plays. It spreads capital equally across 41 holdings, giving smaller aerospace suppliers and emerging space companies the same weight as industry giants like Boeing ( NYSE:BA) and Lockheed Martin ( NYSE:LMT). That structural choice creates a fundamentally different risk profile than market-cap weighted alternatives.
The Direxion NASDAQ-100 Equal Weighted Index Shares ( NASDAQ:QQQE) doesn't generate income the way traditional dividend ETFs do. With just $1.2 billion in assets and a 0.35% expense ratio, this fund tracks the NASDAQ-100 using equal weighting rather than market cap weighting. That structural difference means each of the 100 holdings gets roughly 1% of the portfolio instead of letting mega-caps dominate. The result is a growth-focused ETF where dividends are secondary.
The S&P 500 has a concentration problem. At the start of 2026, the top seven stocks account for roughly a third of the market-cap weighted index, leaving investors heavily exposed to a handful of mega-cap technology companies. Invesco S&P 100 Equal Weight ETF ( NYSEARCA:EQWL) offers a different approach: it takes the 100 largest companies in the S&P 500 and gives each equal weight, capping even giants like Apple Inc. ( NASDAQ:AAPL) and Microsoft Corporation ( NASDAQ:MSFT) at roughly 1% of the portfolio.
