Growth stocks have been the dominant performers for ten plus years. If we are holding an index such as the s and p 500 or total stock market for a very long time, then it seems plausible we could see a reversal where value stocks out perform their growth counterparts. The matrix book is put out by dimensional fund advisers every year and is up dated. It has all this data going back t 19 26, for all of these different factors. So there's data for small cap value back to 19 26, or any other thing you want to look at.
