Oil prices have surged 48% in a single month. The VIX sits in elevated uncertainty territory. Retirees who spent years building portfolios are asking a reasonable question: should I be doing something right now? For many, the answer is probably less than they think. But what they hold matters enormously.
SPDR Portfolio S&P 500 ETF (NYSEARCA:SPLG) rarely gets headlines, yet quietly earns its place in a retirement portfolio. With an expense ratio of just 0.02%, it is the lowest-cost way to own the S&P 500 as an ETF.
What SPLG Is Built to Do
SPLG’s mandate is straightforward: track the total return performance of an index that follows large capitalization exchange-traded U.S. equity securities, benchmarked to the S&P 500. No derivatives, no options overlays, no income engineering. The fund makes money the same way the American economy does: through earnings growth and reinvested dividends of 500 large U.S. companies. For retirees who want core equity exposure without complexity, SPLG delivers exactly what it promises.
The Iran Backdrop and What History Shows
The current environment is genuinely unsettling. WTI crude oil has surged WTI crude oil has surged 48% in a single month in a single month to $93 per barrel as of mid-March, a direct reflection of conflict-related supply disruptions that markets are pricing in rapidly. That anxiety is visible in the VIX, which sits at 25.09 — a level historically associated with meaningful investor stress. Against that backdrop, SPLG is down about 3% year-to-date, less a warning sign than a reminder that broad equity indexes absorb geopolitical shocks differently than commodity markets.
History offers a useful counterweight. Investors who sold at the first sign of conflict typically fared worse than those who stayed put.
SPLG’s longer-term track record reflects this resilience. Over the past year, the fund has returned 19%, and over a decade it has compounded to more than more than 283% — a result of staying invested through multiple crises, including COVID, rate hike cycles, and geopolitical shocks. That long-run compounding is precisely what retirees with a 10-to-20-year horizon are trying to capture, and it is only accessible to investors who did not sell during the scary moments.
Tradeoffs Retirees Should Understand
SPLG is not a defensive fund. Its top holdings are heavily concentrated in mega-cap technology: Nvidia, Apple, and Microsoft together represent a substantial share of the portfolio. A geopolitical shock that specifically hammers tech valuations would hit SPLG harder than a more equally weighted fund.
Retirees also need to weigh equity exposure against bonds. The 10-year Treasury currently yields 4.2%, a meaningful income stream with far less volatility. For someone drawing down a portfolio rather than accumulating, sequence of returns matters: a 10% to 15% drawdown early in retirement is more damaging than the same drawdown a decade in.
There is also the comparison to lower-volatility alternatives. Invesco S&P 500 Low Volatility ETF (NYSEARCA:SPLV) returned 8.8% year-to-date through February 2026, showing how defensive positioning can outperform during stress. SPLV costs more at 0.25% and tilts heavily toward utilities, but offers a smoother ride for retirees with lower risk tolerance.
SPLG has historically served as a core equity sleeve in retirement portfolios for investors with higher risk tolerance. Those with lower risk tolerance or income needs have historically paired broad market ETFs with bonds or lower-volatility alternatives, according to financial planning research.
