What Difference Do Dividends Make?
研究了股息支付股票的投资收益，发现高股息股票风险更低但年收益比无股息股票高1.5%以上，且对成长型和小盘股收益最大，同时价值投资策略应关注无股息股票。
We evaluate the investment benefits of dividend-paying stocks and identify three major findings. First, high-dividend payers have the least risk yet return over 1.5% more per year than do nondividend payers. Second, the benefit of targeting dividend payers is conditional on investment style. Surprisingly, the benefit is largest for growth and small-cap stocks, the stocks of companies usually thought to benefit the most from reinvesting their cash flows. Third, long–short managers exploiting the value premium should focus on non-dividend-paying stocks as non-dividend-paying small-cap value stocks return 1% more per month than do non-dividend-paying small-cap growth stocks.
