The S&P 500 dropped below a key technical level this week, threatening a year-end rally

The S&P 500 briefly rallied on optimism around Nvidia’s quarterly report but remains under pressure from stretched AI valuations and is down at least 1% on the week after trading below its 50-day moving average for the first time in 138 sessions and breaching the lower bound of a rising price channel. LPL Financial strategist Adam Turnquist warns that deteriorating momentum, breadth and leadership raise the odds of a 10%+ correction, citing near-term downside targets of 6,550 and 6,200 (levels that would test the 200‑day MA and could call the bull market’s continuation into question). Defensive sectors are already outperforming (health care up ~5% in November) and historical patterns after long runs above the 50‑DMA point to potentially muted 12‑month returns, suggesting limited scope for a year‑end rally if AI stocks keep weakening.

Analysis

The S&P 500 is attempting to halt a four-day slide on Wednesday as hopes build that Nvidia's third-quarter report will avoid a negative surprise, yet all three major U.S. indexes remain down at least 1% on the week. The index closed below its 50‑day moving average for the first time in 138 trading days and traded beneath the lower boundary of its rising price channel, a dual technical breach that LPL strategist Adam Turnquist flags as elevating pullback risk.

Turnquist cites deteriorating momentum, market breadth and leadership as collective signals that raise the odds of a correction of 10% or more; historically the recent extended run above the 50‑DMA was the 18th such instance since 1950, and prior ends to such runs produced an average 12‑month return of 6.2% versus a 9.5% norm. Defensive positioning is already evident: health care is the strongest sector in November, up about 5%, indicating risk‑off rotation.

He offers near‑term downside targets of 6,550 and 6,200 for the S&P — levels that would test the February highs and the 200‑day MA — and warns that a decisive break below those supports would force a re‑evaluation of whether the bull market can continue.

Key Decisions for Investors

• Trim or hedge high‑multiple AI and growth exposures (including NVDA) ahead of earnings and given the 50‑DMA breach and elevated correction risk
• Shift a portion of equity allocations toward defensive sectors such as health care or increase cash weighting, reflecting the ongoing risk‑off rotation and relative outperformance of defensives
• Implement defined hedges (put protection or modest inverse exposure) for core long positions and monitor whether the S&P holds the 200‑day MA near February highs; if it breaks toward 6,200, reassess for a larger de‑risking move
