Introduction

Of the 20 stock categories that I follow (see articles here), 4 declined in excess of 20% in November, another 3 by at least 10%, and 8 by lesser amounts, leaving only 5 categories that actually increased. This article highlights the performances of the 4 categories that declined in November, in descending order, and their constituents, and the reasons behind the category declines.
