Most Indian investors track portfolio performance — returns, XIRR, how they compare to NIFTY. Fewer investors run a portfolio diagnosis — a structural analysis of the risk profile: how concentrated the portfolio is, how many truly independent positions it contains, how it behaves relative to the market, and whether it is structurally suitable for downside protection. These two things — performance tracking and risk diagnosis — are entirely different activities, and most investors only do the first one.
What a Portfolio Diagnosis Measures
1. Concentration Risk
Measures whether too much of the portfolio's value is concentrated in a small number of positions or sectors. A concentration risk score above a threshold indicates that a single adverse event — a fraud discovery, a regulatory setback, a commodity cycle reversal — could cause a disproportionate portfolio impact. Read our concentration risk guide for the full framework.
2. Effective Holdings
Converts your portfolio's weight distribution into a single number representing how many truly independent bets the portfolio represents. A portfolio with 40 stocks but Effective Holdings of 8 behaves like 8 independent positions — the apparent diversification is illusory. Read our portfolio size guide for what Effective Holdings means practically.
3. Portfolio Beta
Measures how much the portfolio moves relative to its benchmark. Beta of 1.2 means 20% more volatility than the index in both directions. This determines the expected downside in any market correction scenario. Read our portfolio beta guide for the full explanation.
4. Beta Coverage
The percentage of portfolio value with usable historical beta data. If coverage is 60%, only 60% of portfolio value is captured in the beta calculation — the rest is uncharted. Low beta coverage makes the beta number less reliable and reduces the precision of any index-based hedge.
5. Protection Readiness
Whether the portfolio is structurally suitable for hedging — covering beta coverage level, best benchmark match, and the completeness of data needed for scenario simulation. Read our hedging readiness guide for how this classification works.
What a Diagnosis Cannot Tell You
A portfolio diagnosis is not investment advice. It does not tell you which stocks to buy or sell. It does not predict returns. It does not tell you whether any specific position will go up or down. What it tells you is the structural risk profile of the portfolio as it currently stands — the facts about concentration, diversification, and market sensitivity that are knowable now, before any correction tests them.
LaHaie runs this complete diagnosis from your broker's holdings file — Zerodha, Kotak, or Groww portfolio export — and produces a full Portfolio Intelligence Report covering all five dimensions. The diagnosis is the starting point for every risk management decision: rebalancing, position sizing, hedging, and drawdown planning. Use our BBS Stock Scorecard to evaluate individual positions after the portfolio-level diagnosis identifies which positions are contributing most to risk.
🔍 BBS Insight
The most important use of a portfolio diagnosis is not validating that your portfolio looks fine — it is discovering where it does not. Most investors who run their first portfolio diagnosis on LaHaie discover at least one surprise: a position that has grown larger than intended, an Effective Holdings number far below the raw stock count, a beta significantly above 1.0 that the investor did not realise, or a protection readiness that is lower than assumed. These surprises are not failures — they are the value of the diagnostic. Catching these structural issues before a correction is infinitely preferable to discovering them during one.
