Analysis of Reddit Claim: Walmart (WMT) 'Carrying' the S&P500 Amid Tech Sector Lag

A Reddit post (timestamp: 2025-11-21 EST) claimed Walmart (WMT) was “carrying” the S&P500 while Nvidia (NVDA) and AI stocks lagged, suggesting a market rotation from technology to consumer defensive sectors. The post highlighted WMT’s outperformance on November 20 as evidence, though comments disputed the claim due to WMT’s small index weight [3].

• Relative Outperformance
  : On November 20, WMT rose +3.05% amid a broader market decline where the S&P500 dropped -2.96% and NVDA fell -7.81% [0,1,2]. This aligns with the rotation narrative but does not mean WMT “carried” the index.
• Index Contribution
  : WMT’s estimated S&P500 weight (~1.68% based on its $839.7B market cap vs. the S&P500’s ~$50T total market cap) limits its impact on the index [5]. The S&P500’s +0.72% gain on November 21 was driven by Healthcare (+1.73%) and Industrials (+1.52%), not WMT [4].
• Sentiment
  : The post reflects a perception of defensive strength, but data shows it was short-term relative outperformance, not structural leadership.

• WMT’s YTD gain (+17.02%) and 1-year return (+19.15%) indicate sustained defensive appeal, while NVDA’s recent losses reflect tech sector volatility [5].

Metric	WMT	NVDA	S&P500
5-Day Performance	+5.11%	Negative	-1.0% (Nov17-21)
Nov20 Change	+3.05%	-7.81%	-2.96%
Market Cap	$839.7B	N/A	~$50T
Sector Performance (Nov21)	Consumer Defensive (+0.5%)	Technology (+0.14%)	N/A

• Direct
  : WMT (consumer defensive), NVDA (technology).
• Sectors
  : Consumer Defensive (outperformed tech Nov20-21), Technology (lagged).
• Index
  : S&P500 (broader drivers beyond WMT).

• Exact S&P500 weight of WMT (estimated ~1.68% but unconfirmed via direct data).
• NVDA’s fundamental drivers (e.g., AI demand) behind its Nov20 drop.

• Exaggerated Claims
  : The Reddit post’s “carrying” narrative is misleading—WMT’s small index weight limits its impact.
• Rotation Risks
  : Short-term defensive outperformance may reverse if tech rebounds.
• Key Metrics to Monitor
  : WMT’s earnings sustainability (recent beat drove Nov20 gain), NVDA’s AI demand trends, and sector rotation persistence.
