What it means (plain English)

A style box places portfolios on market cap (large/mid/small) and style (value/blend/growth) axes—popularized by Morningstar, adapted for PMS via holdings analytics.

Indian PMS may claim 'value' while style box shows growth tilt on P/B and earnings growth. Factsheet market cap buckets help; deeper style needs factor data or platform analytics on Know Your PMS.

Style box drift across years shows mandate evolution—large-cap value migrating to mid-cap growth is risk profile change.

Use style box to match allocation: don't buy second growth box if portfolio already growth-heavy via other PMS.

Worked example (Indian PMS scenario)

Morningstar-style box placement: large-cap value quadrant based on median market cap ₹35,000 cr and value scores (low P/B, high dividend). Marketing says 'growth PMS' but factsheet metrics say value—explains FY23 underperformance in growth rally.

Your asset allocation assumed 30% growth tilt; this PMS adds value factor unintentionally. Combined style box of total wealth skews value—fine if deliberate, problematic if you wanted growth for 15-year horizon.

Recompute style box quarterly from holdings; Indian PMS rarely publish it explicitly—derive from median cap, P/E, P/B vs benchmark constituents.

Why it matters for PMS scheme selection

Style box makes abstract 'value' or 'growth' labels concrete—essential for diversification and drift detection.

FAQs

Do Indian PMS publish style boxes?

Some institutional decks do; many don't. Platforms may infer from holdings—verify methodology.

Style box vs sector allocation?

Complementary—box is cap/style factors; sectors are industry bets. Both needed.

Can style box change fees or benchmark?

If drift is material, renegotiate benchmark or reconsider mandate fit—drift with old benchmark flatters or punishes falsely.
