Risk and return measures — CFP IPS

Returns matter, but the risk taken to earn them matters too. A 14% return at 25% volatility is very different from 14% at 8% volatility. Risk-adjusted measures combine both into single numbers usable for comparison. This sub-module covers the practitioner's shortlist — Sharpe, Sortino, Treynor, Jensen, Information Ratio — and when each is most appropriate.

Foundation

Risk metrics: • Standard deviation (σ): total volatility around the mean. Captures both upside and downside. • Beta (β): sensitivity to market index. β > 1 = aggressive, β < 1 = defensive. • Alpha (α): excess return over CAPM-predicted. Skill measure (with caveats). • Tracking error: SD of fund return minus benchmark return. Lower = closer to benchmark. • Maximum drawdown: largest peak-to-trough loss over a period. Risk-adjusted measures: • Sharpe = (return − risk-free) / σ. Total-risk-adjusted. • Sortino = (return − risk-free) / downside-σ. Downside-only-adjusted. • Treynor = (return − risk-free) / β. Market-risk-adjusted (assumes diversified portfolio). • Jensen's alpha = return − [risk-free + β × (market − risk-free)]. Excess over CAPM expectation. • Information Ratio = (return − benchmark) / tracking error. Active manager efficiency.

Deep Dive

Worked computations: A fund returned 16% with SD 18%. Risk-free rate 7%. Market return 13% (SD 16%, β of fund = 1.05). Sharpe = (16 − 7) / 18 = 0.50 Treynor = (16 − 7) / 1.05 = 8.57 Jensen α = 16 − [7 + 1.05 × (13 − 7)] = 16 − 13.3 = 2.7% Fund's Sharpe of 0.50 is decent (>0.4 is okay; >0.6 strong; >1.0 rare). Jensen alpha of 2.7% suggests skill — but check statistical significance (alpha t-stat = α/SE(α)). Indian large-cap fund typical metrics: • Sharpe: 0.3-0.5 (median; some funds reach 0.6+) • Beta: 0.85-1.05 • R² vs NIFTY: 0.85-0.95 • Tracking error: 3-7% per year • Max drawdown (5-year): 35-45% For active funds, Information Ratio > 0.5 is good (alpha 2-3% over 4-5% tracking error). Most don't achieve this consistently.

Worked example

Worked example — comparing two equity funds Fund A: 12% return, SD 16%, β = 0.95, max drawdown 32%, R² vs NIFTY = 0.92 Fund B: 14% return, SD 22%, β = 1.20, max drawdown 45%, R² vs NIFTY = 0.85 Risk-free 7%, NIFTY 12% (SD 17%). Sharpe A = (12 − 7) / 16 = 0.31 Sharpe B = (14 − 7) / 22 = 0.32 Treynor A = (12 − 7) / 0.95 = 5.26 Treynor B = (14 − 7) / 1.20 = 5.83 Jensen α A = 12 − [7 + 0.95 × (12 − 7)] = 12 − 11.75 = 0.25% Jensen α B = 14 − [7 + 1.20 × (12 − 7)] = 14 − 13.0 = 1.0% Observations: • Sharpe is essentially equal — fund risk-adjusted performance is similar. • Treynor and Jensen suggest Fund B has slightly more alpha. • Max drawdown: Fund B much worse (45% vs 32%) — significant emotional impact. • For risk-tolerant client: Fund B's slightly higher absolute return + alpha may be acceptable. • For risk-averse client: Fund A's lower drawdown is preferable despite lower return. The CFP's job: match the choice to client risk tolerance, not just chase higher numbers.

Real-world scenario

Real-world scenario — Mrs. Bansal's "10% loss" panic Mrs. Bansal, 60, just retired. Her portfolio dropped 10% in a single quarter. She panics and asks her CFP to liquidate everything. CFP's analysis: • Her portfolio: 50% equity, 50% debt • SD of equity portion (annualised): 18%; SD of debt portion: 4%; portfolio SD ≈ 9.5% • A one-quarter 10% loss for the portfolio is roughly 1.5 standard deviations from mean. • Empirically, this happens ~5-10% of quarters. Not unusual. • Her risk tolerance was assessed as "moderate" 5 years ago. Reality check: this drop is within normal range. However, Mrs. Bansal's behavioural reaction is real. The CFP's response: 1. Acknowledge the loss without dismissing concern. 2. Show the historical context: similar drops have happened many times; equity recovered each time. 3. Reaffirm her allocation matches her plan and goals (essential to revisit IPS). 4. Educate about Sortino — what matters at retirement is sequence-of-returns and drawdown, not absolute volatility. 5. If her fundamental risk tolerance has truly shifted (she's newly retired; first market drop), rebalance to lower-vol mix (40% equity, 60% debt). But do this with a documented decision, not panic-sell at the bottom. This is exactly where CFP value-add separates from DIY. A client buying Direct funds doesn't have this guardrail in panic moments.

Advanced

A nuanced angle: most retail-grade risk metrics are computed over short windows (3-5 years) and miss tail risk. A fund with low SD over 5 years can have one massive drawdown (e.g., debt fund with credit blow-up). Better risk measures for sophisticated analysis: • Maximum drawdown: largest peak-to-trough loss. • Conditional Value-at-Risk (CVaR): expected loss in worst tail (e.g., bottom 5%). • Downside deviation: SD of negative returns only (used in Sortino). • Ulcer Index: time spent in drawdown weighted by drawdown depth. Also: SD assumes normal distribution. Equity returns have fat tails — actual extreme moves are more frequent than normal-distribution would predict. VaR computed under normal assumption systematically understates downside. Sophisticated CFPs combine multiple risk metrics rather than relying on a single number. For client conversations: maximum drawdown is most intuitive ("how bad was the worst stretch"). For comparison across funds: Sharpe and Sortino. For active manager evaluation: Information Ratio + alpha t-stat.

Common mistakes & pitfalls

Using Sharpe alone — misses tail risk and asymmetry.
Comparing risk-adjusted measures across very different mandates.
Ignoring statistical significance of alpha.
Assuming high beta = high return (CAPM is a model, not law).
Reporting volatility without context of investor's specific drawdown tolerance.

Frequently asked

What's a "good" Sharpe ratio for an Indian equity fund?

5-10 year Sharpe of 0.3-0.5 is typical. >0.5 is strong; >0.7 exceptional and rare. Compare fund Sharpe to benchmark Sharpe — fund needs higher Sharpe to add risk-adjusted value.

Sharpe vs Sortino: which is better?

Sharpe penalises both up- and downside volatility equally. Sortino penalises only downside. For most investors who don't mind upside surprise, Sortino is more relevant. CFPs often use both for completeness.

How do I explain risk to a risk-averse client?

Focus on maximum drawdown ("worst case in past 5 years"), not standard deviation. Drawdown is intuitive; SD is statistical. Show the historical worst-case loss for each portfolio mix. Match the mix to their drawdown tolerance, not their stated risk preference.

Practice questions

Click each question to reveal the answer and explanation.

Q 1

A fund has 14% return, SD 20%, risk-free 7%. Sharpe ratio:

(a)0.20
(b)0.35
(c)0.50
(d)0.70

Correct: (b) 0.35

Sharpe = (14 − 7) / 20 = 0.35. Decent for an Indian equity fund.

Q 2

Beta of 1.2 indicates:

(a)Fund moves 20% less than market
(b)Fund moves equally with market
(c)Fund moves 20% more than market
(d)Fund is uncorrelated with market

Correct: (c) Fund moves 20% more than market

β = 1.2 means fund moves 20% more than market. If market is up 10%, fund expected up 12%; if market down 10%, fund down 12%.

Q 3

Jensen's alpha measures:

(a)Total portfolio return
(b)Excess return over CAPM-predicted (market exposure adjusted)
(c)Standard deviation
(d)Tracking error

Correct: (b) Excess return over CAPM-predicted (market exposure adjusted)

Jensen α = actual return − [risk-free + β × (market − risk-free)]. Excess over CAPM expectation; measures manager skill (or luck — must test significance).

Q 4

A risk-averse retiree most cares about:

(a)Maximum drawdown
(b)Information Ratio
(c)Treynor ratio
(d)Tracking error

Correct: (a) Maximum drawdown

Maximum drawdown — the worst peak-to-trough loss — is the most relevant for a retiree because it captures emotional and financial pain of a single bad period. A retiree relying on portfolio for income cannot easily wait out long drawdowns.

Q 5

Sortino ratio uses:

(a)Standard deviation in denominator
(b)Beta in denominator
(c)Downside deviation in denominator
(d)Tracking error in denominator

Correct: (c) Downside deviation in denominator

Sortino = (return − risk-free) / downside deviation. Penalises only downside volatility, treating upside as good. Often more intuitive for client communication.

Q 6

A fund with low Sharpe and high alpha may have:

(a)Pure skill
(b)Pure luck
(c)Possibly high tracking error vs benchmark
(d)No risk

Correct: (c) Possibly high tracking error vs benchmark

Low Sharpe + high alpha can indicate the fund deviates significantly from benchmark (high tracking error) — capturing alpha through a non-market-correlated bet, but with associated active risk. CFPs check Information Ratio for full picture.
