Two methods to improve the results:
1) Combine smaller portfolios that make sense to combine - for example retail trade could be paired with consumer non-durables. I will continue Y-6 with the portfolios as planned however, and then evaluate which ones could or should be combined.
2) Combine small groups together. For example, if one group only has one or two companies, move it to a higher or lower group.
Combined portfolio Candidates:
- Producer Mfg & Process Industries.
