Low wages, high youth unemployment and a feeble social safety net mean China's household spending is less than 40% of annual economic output, some 20 percentage points below the global average. Investment, by comparison, is 20 points above.

China's finance minister says the government is looking at additional ways to boost the economy, but he didn't unveil a major new stimulus plan at a news conference Saturday.

Meanwhile, one expert suggested that investors are misunderstanding China's intent in providing the stimulus boosts. According to Arthur Kroeber, founding partner of Gavekal Dragonomics, Beijing's intent isn't to accelerate the economy by enabling consumers, but simply to stabilize it.
