Value-weighted, without changing your records.
Holding value = saved share quantity × your manually entered price. Only positive values you include are analyzed.
HHI is the sum of squared decimal weights × 10,000. Effective count is 1 ÷ the sum of squared decimal weights.
Equal-weight reference is 100 ÷ the number of included positive-value holdings. Duplicate symbols stay as separate holdings.
About this analysis.
Does this change my portfolio?
No. The analyzer is read-only, and inclusion choices exist only for this page session.
Are these live market values?
No. Every value uses the price saved manually in your portfolio.
Does HHI tell me what to buy or sell?
No. It is only a mathematical concentration measure, not a risk label or recommendation.
