Sharpe ratio example with Excel

Intro If you’re dipping toes into prop trading, you’ve probably felt the pull of a clean, comparable metric. The Sharpe ratio offers that clarity: risk-adjusted performance you can trust across assets. Excel keeps this honest and approachable, letting a trader quickly sanity-check strategies whether you’re chasing forex moves, stock swings, or crypto volatility.

What the Sharpe ratio measures Think of it as the extra return you earn per unit of risk. It’s the average excess return (over a risk-free rate) divided by the variability of those returns. In the real world, that means you’re not chasing big wins that come with big ups and downs; you’re chasing steady, repeatable upside per unit of risk. If you’ve sat with a dashboard late at night, you know numbers don’t lie—they just tell a story you’ll either learn from or ignore.

A practical Excel-backed example Imagine you’ve tested three ideas across daily data: a forex pair, a tech stock, and a crypto token. You pull daily returns for each, pick a reasonable risk-free rate (say a short-term treasury yield), and compute the mean excess return and the standard deviation of returns. The Sharpe ratio emerges as a simple quotient: higher is better, all else equal. Convert to an annualized view if you’re working with daily data (there’s a standard multiplier for that), then compare the ratios side by side to decide which approach looks most durable. You don’t need fancy software to do this; what matters is consistency and a clean data feed.

Multi-asset testing: advantages and caveats

• Forex: liquid, tight spreads, good for backtesting many days; watch for regime shifts and liquidity squeezes.
• Stock: equity risk premium is familiar, but dividend adjustments and price gaps matter.
• Crypto: volatility can juice the Sharpe, but data quality and exchange reliability are critical.
• Indices: broad exposure helps smooth some risk, though correlations shift.
• Options: risk can explode; use the ratio to compare defined-risk strategies versus outright directional bets.
• Commodities: seasonality and carry must be considered; storage costs aren’t always obvious.

Reliability tips and strategies

• Use clean, consistent data and a clearly defined period.
• Align the risk-free rate with your chosen horizon and asset class.
• Backtest with walk-forward validation to avoid overfitting.
• Pair Sharpe results with drawdown, win-rate, and maximum adverse excursion for a fuller picture.
• Don’t chase a single high ratio; look for robustness across regimes.

DeFi, challenges, and the road ahead DeFi tempts with transparency and open access, but price feeds, smart-contract risk, and liquidity fragmentation complicate the math. Oracles can misprice assets, and sudden liquidity drains alter realized risk. The future lies in resilient oracles, secure on-chain governance, and better risk controls that parlay Excel-style backtests into on-chain, guarded execution.

Smart contracts, AI, and prop trading Smart-contract trading promises speed and programmability; AI adds pattern recognition and adaptive risk management. Expect hybrid models: on-chain signals refined with off-chain backtests, all screened through transparent Sharpe-based comparisons.

Prop trading outlook Across forex, equities, crypto, indices, options, and commodities, the edge comes from disciplined risk budgeting, cross-asset calibration, and honest measurement. Excel remains a practical navigator: quick insight, shared language, and a portable workflow that travels with you from a coffee shop to a pro desk.
