The S&P 500 Is Close to Its All-Time High. Should This Excite or Worry Investors Going Into 2026?

After the S&P 500 hit an all‑time high on Oct. 29 (~6,890 points) and was trading near that level (~6,870) as of Dec. 8, the Motley Fool argues investors should favor disciplined buying over market timing—recommending dollar‑cost averaging into an S&P 500 ETF such as Vanguard’s VOO (closing price on Oct. 29 $631.95) rather than sitting on the sidelines. The piece emphasizes VOO’s diversification, proven long‑term performance and ultra‑low expense ratio (0.03%) as reasons to keep it as a core holding despite acknowledging historically high valuations. Disclosure notes the author and Motley Fool hold and recommend VOO while also promoting Stock Advisor’s 10 stock picks that it believes could outperform the ETF.

Analysis

The S&P 500 reached an all-time high on Oct. 29 (~6,890 points) and was trading near that level at ~6,870 on Dec. 8, prompting both momentum-following behavior and concern about elevated valuations. Market signals accompanying the article register a moderately positive, bullish tone (sentiment_score 0.4, market_impact_score 0.25), suggesting investor positioning favors continued gains despite caution.

The article advocates disciplined dollar-cost averaging into a Vanguard S&P 500 ETF (VOO), noting sequential all-time closing highs this year (VOO closing prices: Oct. 29 $631.95; Oct. 8 $618.77; Sept. 22 $614.76; Aug. 28 $596.52; Aug. 14 $592.85) and highlights VOO’s diversification and ultra-low expense ratio (0.03%) as reasons to hold it as a core position. The author explicitly states VOO is his largest holding into 2026 and recommends a long-term focus rather than market timing.

The piece also flags risk and choice: it acknowledges historically high S&P valuations and discloses that the Motley Fool and the author hold and recommend VOO while promoting a separate Stock Advisor top-10 list (claimed average return 981% vs S&P 194%), creating an active-versus-passive tradeoff. Investors should weigh a low-cost passive core with selective active ideas, and remain prepared to adjust sizing if valuation or macro dynamics materially change.

Key Decisions for Investors

• Establish or maintain a core allocation to a low-cost S&P 500 ETF such as VOO and implement dollar-cost averaging rather than attempting to time market entries
• Given the article's note on historically high valuations, stagger purchases or limit initial position size to manage downside risk while DCA builds exposure
• Treat Stock Advisor or other active ideas as satellite positions to a VOO core and independently vet those picks given the disclosed conflicts and outperformance claims
• Set clear monitoring triggers for valuation shifts or "extreme, unforeseen" events and predefine rebalancing or risk-management rules aligned to your portfolio tolerance
