Assigning a Weight to Each Measure of Competitive Strength Assessment

Assigning a weight to each measure of competitive strength assessment is generally analytically superior because

A) a weighted ranking identifies which competitive advantages are most powerful.
B) an unweighted ranking doesn't discriminate between companies with high and low market shares.
C) it singles out which competitor has the most competitively potent core competencies.
D) weighting each company's overall competitive strength by its percentage share of total industry profits produces a more accurate measure of its true competitive strength.
E) all of the various measures of competitive strength are not equally important.
