Wealth Concentration: The Top 10% Own 87% of Stocks — Market & Options Implications

The Wealth Gap Is Real—and Getting Bigger

According to Ritholtz Wealth Management and author Ben Carlson on his blog A Wealth of Common Sense, the top 10% of American households now own:

• ~87% of all publicly-traded stocks.
• ~84% of private businesses
• ~44% of real estate.
• Over two-thirds of overall wealth.

Meanwhile, the bottom 80% hold a shrinking share of each asset class. This isn’t just a social commentary—it is a structural shift with market consequences.

Why This Matters for Stocks & Options

Consumer Spending Power Is Skewed

The top 10% now accounts for roughly 50% of all consumer spending in the U.S.—a dramatic shift from decades past when their share was far lower.
That means companies whose revenue depends on mass-market consumption may struggle if the bulk of spending is concentrated among a narrow demographic.

Market Concentration = Risk of Narrow Rallies

If almost all value is concentrated in a small group who own most stocks, then broad market rallies become vulnerable if that group pulls back. The upside may be limited to a few mega-caps, while the rest of the market languishes.
Options traders should watch for:

• Elevated implied volatility in narrow-market names (mega-caps) versus the broad indices.
• Divergences such as big cap calls being bid while small-cap puts start flowing.

Names to Watch

• SPY (S&P 500 ETF) – look for skew between mega-cap exposure vs. broad index.
• QQQ (Nasdaq-100 ETF) – heavy concentration in tech/large caps means risk is skewed.
• IWM (Russell 2000 ETF) – more diversified exposure; may underperform if wealth concentration persists.
  Options flow: bullish call interest on mega-caps may be a sign of concentration; protective put interest in broad indices may signal fear of underlying weakness.

Structural Risks: What Could Trigger a Market Jolt?

1. Wealth Effect Weakens – If asset prices for the top 10% fall (stocks, real estate, private businesses), their consumption and investment pullback could drag broader markets.
2. Consumer-Cyclicals Suffer – Firms relying on middle-class spending may miss earnings expectations if wealth concentration reduces their customer base.
3. Sentiment Shock in Retail/Institutional Markets – If retail investors perceive the upside has been captured by the few, participation may drop, reducing market breadth.

Trade Ideas & Options Setups

• Small-cap Put Spread: Buy puts on IWM or a small cap index ETF if you believe the wealth effect is narrowing upside to mega caps.
• Large-cap Call Skew: Look for unusual bullish calls on mega cap stocks (e.g., in QQQ) that signal concentration bets.
• Consumer Discretionary Hedging: Use call hedges on mega caps or purchase puts on consumer-cyclical ETFs if you foresee a spending pullback.

Final Take

Wealth concentration isn’t just about fairness—it’s about market mechanics. When 87% of stocks are owned by 10% of households, liquidity, momentum, and breadth become distorted. For traders, that means: be aware of concentration risk, monitor options flow in mega-caps vs. broader indices, and hedge accordingly.
If the top 10% reduce risk appetite, the broader market could face a sudden ripple—even if nothing “bad” happened in headlines.
