“Does the small stock premium as presented in Ibbotson’s data include some of the difference in liquidity between the large stocks and small stocks?” a BVR subscriber asked recently. “Should we be concerned about double-counting the effect of large vs. small stocks?”

For the answer, we turned to Ashok Abbot, Ph.D., Associate Professor of Finance at West Virginia University (Morgantown). “Ibbotson has been revising their size premiums downward,” he says. “A better source is Kenneth French’s data on size premium.” To access the French data, go to http://mba.tuck.dartmouth.edu/pages/faculty/ken.french/data_library.html.
