The Case for Liquidity as an Investment Style (Podcast)
We last talked with Roger Ibbotson, chairman and CIO of Zebra Capital Management, in late 2011, when John Bowman, CFA, interviewed him about his ongoing research on liquidity for our Take 15 video series. Ibbotson’s subsequent paper “Liquidity as an Investment Style” appears in the May/June 2013 issue of the Financial Analysts Journal, and Rodney Sullivan, CFA, recently chatted with him as part of our new series of FAJ author interviews.
Ibbotson says that he and his coauthors — Zhiwu Chen, Daniel Kim, and Wendy Hu — showed that liquidity meets William F. Sharpe’s four criteria for benchmark investment styles. They also constructed portfolios using each investment style (size, value/growth, momentum, and liquidity) and studied the returns. Ibbotson notes that “there was a gain from buying the stock that was less liquid; that was true for high-value stocks, it was true for growth stocks, it was true for high-momentum stocks, it was true for low-momentum stocks.”
Ibbotson says that buying less-liquid stocks “makes more sense than any of these other styles.” To hear all of the benefits he ascribes to liquidity as a style, as well as a more thorough discussion of his research and findings, listen to the complete interview above or download the MP3.
