Tata Consultancy Services and Infosys were strongly correlated from October 17, 2025 to October 16, 2026. The reported average correlation of 0.79 showed strong positive linear co-movement in the observed sample.

Correlation alone does not establish portfolio risk reduction or predict selloff behavior. This comparison does not model a combined portfolio.

Metric	Value
Current (30-day)	0.76
Average (full period)	0.79
Minimum (30-day rolling)	0.51
Maximum (30-day rolling)	0.94

Correlation measures linear co-movement of returns: near +1 indicates strong positive co-movement, near 0 indicates weak linear co-movement, and negative values indicate inverse co-movement. Near-zero correlation does not establish independence. Current, minimum, and maximum figures are 30-day rolling correlations on shared daily returns.

Drawdown

±2.03% 1-day vol

INFY Volatility

33.4%

±2.1% 1-day vol

1-day volatility (1σ)

TCS

±2.03%

INFY

±2.1%

Tata Consultancy Services's 32.3% annualized volatility translates to about ±2.03% one-standard-deviation daily volatility.

Infosys's 33.4% annualized volatility translates to about ±2.1% one-standard-deviation daily volatility.

INFY had the wider volatility profile over this window. That means its day-to-day return distribution was broader; TCS was calmer, but lower volatility does not by itself mean better returns.

Treat the ± daily figure as a one-standard-deviation estimate from historical returns, not a forecast or expected absolute daily move. For context, 15-18% annualized volatility is roughly ±1% one-standard-deviation daily volatility.

Risk-adjusted ratios

Sharpe Ratio of TCS and INFY

Sharpe Ratio: TCS vs. INFY

Return per total volatility

Sharpe gives us excess return per unit of risk. Upside and downside volatility both count as risk.

Higher is better

excess return / total volatility

Formula

\displaystyle \mathrm{Sharpe} = \frac{\mathbb{E}[R] - R_f}{\sigma_R}

Sharpe ratio measures return per unit of risk (volatility). A higher Sharpe indicates better risk-adjusted performance. Both Sharpe ratios were negative (TCS -0.65 vs INFY -0.72), meaning both underperformed the risk-free rate; TCS was less negative.

A Sharpe above 1.0 is generally considered good, above 2.0 is excellent. Negative Sharpe means the asset underperformed the risk-free rate. Calculated on each asset's full 365-day lookback of available prices and annualized using the asset calendar (365 for crypto, 252 trading days for equities/ETFs/metals).

Sortino Ratio of TCS and INFY

Sortino Ratio: TCS vs. INFY

Return per downside volatility

Sortino keeps the return-over-risk idea, but only returns below the target rate count as volatility.

Higher is better

excess return / downside volatility

Formula

\displaystyle \mathrm{Sortino} = \frac{\mathbb{E}[R] - R_f}{\sigma_{\mathrm{down}}}

Sortino ratio measures return per unit of downside risk. Unlike Sharpe, it only counts downside deviation (returns below the target return). TCS had better downside-adjusted returns.

A higher Sortino is better. It's useful when upside volatility is common (crypto is the obvious example). Downside deviation: TCS 23.2% vs INFY 23.8%. Calculated on each asset's full 365-day lookback of available prices, using the daily risk-free rate as the target return, and annualized using the asset calendar (365 for crypto, 252 trading days for equities/ETFs/metals).

Calmar Ratio of TCS and INFY

Calmar Ratio: TCS vs. INFY

CAGR per worst drawdown

Calmar compares CAGR against the single deepest peak-to-trough loss over the period.

Higher is better

CAGR / max drawdown

Formula

\displaystyle \mathrm{Calmar} = \frac{\mathrm{CAGR}}{|\mathrm{MaxDD}|}

Calmar ratio compares CAGR to maximum drawdown. Higher Calmar means more return per unit of worst drawdown. TCS posted the higher Calmar ratio.

Calmar is computed on each asset's full 365-day lookback and uses the max drawdown over that same window.

Sterling Ratio of TCS and INFY

Sterling Ratio: TCS vs. INFY

Return per average drawdown

Sterling smooths the drawdown penalty by using average drawdown events instead of only the worst one.

Higher is better

excess annual return / average deep drawdown

Formula

\displaystyle \mathrm{Sterling} = \frac{\mathrm{CAGR} - R_f}{\overline{D}_{>10\%}}

Sterling ratio measures excess return per unit of average drawdown (typically drawdowns worse than 10%). TCS posted the higher Sterling ratio.

Sterling uses average drawdown events deeper than 10% and subtracts the risk-free rate to report excess return.

Treynor Ratio of TCS and INFY

Treynor Ratio: TCS vs. INFY

Excess return per market beta

Treynor divides excess annualized return by beta — the sensitivity of the asset to broad-market moves. The slope shown is each asset’s beta vs SPY.

Higher is better

excess return / market beta

Formula

\displaystyle \mathrm{Treynor} = \frac{\mathbb{E}[R] - R_f}{\beta}

Treynor ratio measures excess return per unit of market risk (beta) instead of total volatility. TCS posted the higher Treynor ratio.

Treynor uses beta vs the S&P 500 (SPY) on shared dates and the average 3-month Treasury rate as the risk-free rate.

Ulcer Index of TCS and INFY

Ulcer Index: TCS vs. INFY

Drawdown pain

Ulcer Index is a risk index, not a return-over-risk ratio. Lower means smaller and shorter drawdowns.

Lower is better

root-mean-square drawdown

Formula

\displaystyle \mathrm{UI} = \sqrt{\mathbb{E}[D_t^2]}

Ulcer Index captures drawdown depth and duration. Lower Ulcer Index means less drawdown pain. TCS had the lower Ulcer Index (less drawdown pain).

Ulcer Index is computed from each asset's drawdown series over the full lookback window.

Tail Risk & Distribution Shape (1-Year): Tata Consultancy Services vs. Infosys

This section looks at the shape of daily returns, not just the average. Tail stats are computed per asset on its own daily series (crypto includes weekends). We use daily log returns $\ln\left(\frac{P_t}{P_{t-1}}\right)$ so multi-day moves add cleanly.

Definitions: Value at Risk (VaR), Expected Shortfall, skew, kurtosis, and fat tails.

Tail Risk & Distribution Shape: TCS vs. INFY (1-Year)

Actual daily return tails

The bars are real daily log-return observations from the article window. Darker bars are observations at or beyond each asset’s 5% VaR cutoff.

Observed returns

VaR marks the 5th percentile loss cutoff; Expected Shortfall averages the observations beyond that cutoff.

Formula

\displaystyle \mathrm{VaR}_{5\%}=Q_{0.05}(r_t),\quad \mathrm{ES}_{5\%}=\mathbb{E}[r_t\mid r_t\le \mathrm{VaR}_{5\%}]

Metric (1-Year)	TCS	INFY
5% VaR (daily log return)	-3.33%	-3.56%
5% Expected Shortfall (CVaR)	-4.87% (worst 13 days)	-5.00% (worst 13 days)
Skew	-0.10	-0.11
Excess kurtosis	2.58	1.49
2σ tail days (down / up)	8 / 8	7 / 10
Worst day	-8.11% (2026-06-03)	-7.44% (2026-02-04)
Best day	+7.90% (2026-10-13)	+5.52% (2026-01-16)

Downside co-moves (2σ) — 1-Year

Computed on shared dates only (n=245). A “2σ downside move” means a shared-close log return more than 2 standard deviations below that asset’s own mean on this shared-date series. Dates below show simple returns (%) for readability.

Downside co-move map: TCS vs. INFY (2σ)

Shared-close daily returns

Dots mark actual downside days: asset-colored dots are one-sided downside moves, and red dots are joint downside days. Grey dots add sampled shared-return context when available. The shaded lower-left zone shows where both TCS and INFY crossed their own 2σ downside threshold.
