MTUM risk-adjusted returns: Sharpe, Sortino and volatility

Over 5 years, MTUM had a Sharpe ratio of 0.36 against 0.58 for the S&P 500, so it earned less return per unit of risk than the index. Its annualized volatility was 21.1% and its beta 1.08: it tended to move about 1.1× as much as the market.

MetricMTUMS&P 500
Annual return+9.5%+12.0%
Volatility (annualized)21.1%15.5%
Sharpe ratio0.360.58
Sortino ratio0.580.91
Max drawdown (month-end)−30.2%−23.9%
Beta to the S&P 5001.081.00

Sharpe divides return above cash by total volatility; Sortino counts only downside volatility. Both use monthly returns and the 1–3 month T‑bill ETF (BIL) as the risk‑free rate.

How MTUM behaved in past crashes

MTUM’s deepest fall in the crises below was −34.1% in the covid crash (feb–mar 2020), against −34.1% for the S&P 500. The last column turns that into money: what a $100,000 position would have lost from peak to trough.

Peak‑to‑trough declines from daily prices inside each crisis window. A crash replay does not predict the next crisis; it shows how much room a holding needs. Run the same replay on a whole portfolio with the crash test.

What moves with MTUM, and what doesn’t

The right benchmark for MTUM

Exent matches every holding to the index with the most similar risk. For MTUM that is SPY (the S&P 500). Comparing a holding with an index that carries very different risk makes good results look bad and risky ones look clever. Read why the S&P 500 is the wrong benchmark for most portfolios.
