How did Quality and low volatility do after costs and tax?
50% Nifty200 Quality 30, 50% Nifty100 Low Volatility 30, rebalanced each January. From Apr 2005 to Oct 2026 it compounded at 15.1% a year after costs and tax (15.6% before tax), against 11.4% after tax for 60/40. Its worst fall was −52%, bottoming in Nov 2008 and recovered by Oct 2009.
Written for investors weighing this allocation against a plain 60/40, and advisers who want its tax and cost drag measured. Data to 5 Oct 2026.
How it works
One of 136 portfolios in the lab, in the family "Beta plus factors, and factor blends". The rule and its parameters were written down before any result was computed.
Historical research on index portfolios, not investment advice. Returns are after fund costs; 'after tax' applies Indian capital-gains rules by date for a 30% slab investor and sells everything at the end. Most factor, mid-cap and small-cap index history before each index's launch date is back-tested by NSE. One 21-year sample, domestic assets only.

Growth and falls
What one rupee became, and how far it fell on the way. 60/40 is drawn in grey for comparison. Both curves are after fund costs and before tax; the after-tax figures are in the costs chapter.
Growth of 1 rupee
Weekly, shown month by month, Apr 2005 to Oct 2026. After costs, before tax. Log scale. Back-tested before launch: Nifty100 Low Volatility 30 (live from Jul 2016); Nifty200 Quality 30 (live from Apr 2018).
How to read it. On a log scale equal slopes are equal rates of return. One rupee became 22.48× here and 11.21× in 60/40; a steeper line in one stretch says which did better then.
Fall from the previous peak
The lowest weekly reading of each month, per cent below the highest value reached so far.
How to read it. Zero means a new high. The deepest fall here was −52.2% (Nov 2008), against −36.5% for 60/40. Depth is half the story: the width of each dip is how long an investor waited to get back to even.

What costs and tax took
The same Apr 2005 to Oct 2026 run, peeled back one layer at a time. Fund costs are those of the cheapest widely available index fund or ETF of each era; tax applies Indian capital-gains rules as they stood on each sale date, and everything is sold at the end so deferred tax is counted. Turnover was 0.01 times the portfolio a year.
| Layer | Quality and low volatility | Cost of this layer (pts) | 60/40 | More |
|---|---|---|---|---|
| Index return, before any cost | 16.61% | – | 12.48% | |
| After fund costs and trading (before tax) | 15.55% | 1.05 | 11.89% | |
| After tax, 30% slab | 15.13% | 0.42 | 11.41% | |
| After tax and inflation | 8.16% | 6.97 | 4.67% |
| Tax case | Quality and low volatility | 60/40 |
|---|---|---|
| 30% slab, equity exemption off (the headline) | 15.13% | 11.41% |
| 30% slab, equity exemption on (Rs 10 lakh start) | 15.15% | 11.44% |
| 20% slab | 15.13% | 11.42% |
How sure we can be
One 21-year history is one draw. These numbers say how much the result could move with a different ordering of the same months, and how it looks once the 136 portfolios tried are taken into account.
- Return, 90% interval
- 9.2% to 22.5% a year before tax (block bootstrap of monthly returns; the point estimate is 15.6%).
- Against 60/40, 90% interval
- +0.5 pts to +7.2 pts a year. The whole interval is above zero.
- Five-year windows ahead of 60/40
- 95% of rolling five-year windows. The windows overlap: only about 4 of them are independent, so this is a description of the past, not a probability.
- Longest stretch behind 60/40
- 1,427 days
- Deflated Sharpe against 60/40
- 0.13. This is the probability that its edge over 60/40 is real once 136 tries are allowed for; 0.95 would be the usual bar.
- Worst five years after inflation
- −0.7% a year
- Rolling five-year return
- Lowest 3.6%, middle half 13.1% to 17.4%, highest 28.2% a year (before tax).
As a monthly SIP
Rs 10,000 a month, bought at the first session of each month, held for a fixed number of years and then sold, after costs and tax (with the annual equity exemption on). Each start month is one window. Windows that start a month apart share almost all their months, so the number of independent periods is printed next to every figure.
10-year SIP: after-tax return by start month
XIRR of each 10-year SIP, by the month it started (139 windows). Grey: the same instalments in one-year fixed deposits, taxed each year. FD proxy: 364-day T-bill primary yield (91-day before April 2005), after slab tax and cess each year.
How to read it. Each point is a whole 10-year SIP. Neighbouring points share most of their months, so the line is far smoother than the evidence is deep. The best start was Apr 2005 (19.9%), the worst Apr 2010 (7.4%).
per cent a year, after tax
The latest 10-year SIP in the data started in Oct 2016. It put in ₹12,00,000 and was worth ₹19,40,260 after tax at the end, against ₹14,81,288 for the same instalments in fixed deposits.
