RT Journal Article SR Electronic T1 Remarks on the Calculation of Earnings in the S&P 500 Index JF The Journal of Investing FD Institutional Investor Journals SP 15 OP 17 DO 10.3905/joi.2011.20.3.015 VO 20 IS 3 A1 Michael Keppler A1 Xing-Hong Xue YR 2011 UL https://pm-research.com/content/20/3/15.abstract AB Jeremy J. Siegel questioned Standard & Poor’s methodology regarding the earnings calculation of the S&P 500 Index, arguing that it gave far too much influence to firms with big losses and low market values, and thereby gave a distorted valuation to the S&P 500 Index. While Siegel’s arguments are understandable from an investor’s point of view, his suggestions on how to address the issue are questionable.TOPICS: Mutual funds/passive investing/indexing, statistical methods, security analysis and valuation
