Ask a financial adviser anywhere in the world for a sensible portfolio and you will hear the same recipe. The 60 does the growing. The 40 keeps the boat steady—which is why finance borrowed a sailing word for it: ballast. On a ship, ballast is the heavy material—stone, iron, seawater—loaded low into the hull. It does not make the ship faster. It keeps the ship upright when the weather turns. In a portfolio, ballast is an asset that holds its value while the growth assets are being thrown around, so the whole portfolio never sinks as far as its riskiest part. The recipe travels under different names in different places—a balanced fund, a pension mix, a moderate allocation—but underneath they are all the same 60/40, and it has been the benchmark for balanced investing for roughly fifty years.
Crypto copied the 60 and never found a 40. BTC and ETH turned out to be two of the great growth assets of the era, but everything tried as ballast beside them has failed the audition: the major alternative coins move nearly in step with BTC, and stablecoins hold their price by earning nothing at all. A crypto portfolio has been all engine and no ballast since the day it existed. So we measured what the last six years would have looked like if crypto had a real 40.
First, the yardstick
The Sharpe ratio answers one question: how much did an investment earn above cash, per unit of volatility—how widely its daily returns swing, scaled to a yearly figure? Divide the return above cash by the swing and you get a score on which a wild asset and a calm one can compete fairly. Higher is better; zero means cash did just as well; a negative score means cash did better. We lean on it for the same reason the rest of the industry does: raw return flatters whatever happened to swing hardest in a lucky direction, while return per unit of risk measures what an investor was actually paid for what they had to sit through—the only fair scoreboard when one asset swings four times harder than another.
The measure has a history. William F. Sharpe proposed it in 1966 under the name reward-to-variability ratio; the industry kept the idea, shortened the name to his, and has used it as the default scorecard for fund performance ever since. The work earned him a share of the 1990 Nobel Memorial Prize in Economics.
How we measured it
The token numbers come from our own pricing engine: daily returns for RiskOFF and for the BTC and ETH it is built on, from 2020 through July 20261. The benchmarks—the S&P 500, US bonds, gold, and Treasury bills—come from the standard public sources2. Two portfolios do the work: a BTC 60/40, which is 60% BTC and 40% RiskOFF BTC3, and an ETH 60/40, which is 60% ETH and 40% RiskOFF ETH. Each is rebalanced monthly, and each faces the same judges: its own raw asset, and the classic 60/40 of stocks and bonds run the same way.
The job description of a 40
A 40 has three duties. First, it must hold its value in the storm—when the growth side falls by two-thirds, the ballast is the part that does not. Second, it should earn something while it waits: ballast that pays nothing is dead weight, and dead weight quietly loses to everything around it. Third, it must still be worth something on the day the growth side goes on sale. Rebalancing—selling whichever side has drifted above its target weight and buying the one that has fallen below—is how a portfolio turns a crash into a purchase, and it only works if the 40 kept its value while the 60 was falling. A ballast that crashes with the engine has nothing left to spend at the bottom.
The recipe is older than its mathematics. Balanced stock-and-bond funds date to 1929, when the Wellington Fund carried a bond sleeve through the Depression; Harry Markowitz supplied the formal argument in 1952, in the paper that founded modern portfolio theory and later shared the same 1990 Nobel that honored Sharpe. Somewhere between those two dates and now, the institutional world settled on 60/40 as the reference blend, and it has kept the job ever since.
The year the ballast sank
Then 2022 happened to it. The classic 60/40 lost 15.8%—not because stocks fell 18%, which is what stocks do, but because bonds fell 13% in the same year, the one thing the recipe assumes cannot happen. By one long-running tally it was the worst year for US bonds since 19374, and the worst year for the blended portfolio since the global financial crisis.
And 2022 was not the whole problem. Across our full window, US bonds returned 0.8% a year while cash—in the TradFi sense, meaning 3-month Treasury bills—paid 2.9%. On the yardstick above, that is a Sharpe ratio of −0.30. For six straight years, the world’s default ballast was a worse place to stand than a money-market account.
Crypto never had one
Crypto’s problem is the mirror image. It has never lacked growth. It has lacked anything worth putting beside the growth, and the shortage shows up in the oldest statistic in this article: correlation, the measure Karl Pearson formalized in the 1890s for how two series move together. It runs from +1 (lockstep) through 0 (strangers) to −1 (opposites). Ballast lives near zero or below: an asset that ignores the engine’s weather. Every candidate crypto has produced lives near +1 instead. Over the last six years the major alternative coins’ daily moves ran 0.42 to 0.82 correlated with BTC’s—statistically the same trade wearing different logos. And the coins at the low end of that range are not calm—they are chaotic. DOGE, the least correlated of the majors, lost 40% in a single day inside the window; SOL lost 42% in one. Low correlation earned through wildness is not ballast. It is a second storm.
The other candidate is stablecoins, and they fail the second duty instead. A stablecoin holds its dollar price by holding nothing else: it pays no yield, so it does not even keep pace with the T-bills that TradFi calls cash—the same 2.9% a year that made the classic 40’s six years look so poor.
Rebuilt with a real 40
RiskOFF is our candidate for the missing 40: a token built on BTC or ETH that gives up its upside beyond a point in exchange for a floor in case of losses. It holds its value in crypto’s storms, and it earned while it waited—11.9% a year on ETH and 8.2% on BTC across the window, turning $1 into $2.08 and $1.68. Whether it fills the job is exactly what the two portfolios test.
So we put it to work. Sixty cents of every dollar goes to the asset; forty cents goes to the RiskOFF built on that asset; once a month, the portfolio is traded back to 60/405. Over six and a half years of data that meant 78 rebalances per portfolio. On the ETH version, 42 of them trimmed the engine after it ran and 36 added to it after it fell, and the median trade moved just 2.8% of the portfolio; the BTC version split 45 and 33 with a median of 1.9%. In plain terms, a typical rebalance shifted two or three cents of every dollar from one sleeve to the other—on a $10,000 portfolio, a trade of two or three hundred dollars. Small, boring, mechanical—and that is the whole strategy.
Two more yardsticks appear in the table, both defined here. CAGR is the compound annual growth rate, and the Calmar ratio divides that growth by the deepest drawdown—the fall from a peak to the lowest point after it—so it scores growth per unit of worst pain. Higher is better: the highest scores go to assets that grow fast without ever falling far. Terry W. Young introduced it in 1991 and named it after his newsletter, the CALifornia Managed Account Reports. It caught on first among futures traders—they trade with leverage, so a single deep fall can wipe an account to zero, and they wanted the score that punishes exactly that—and it stuck as the industry’s pain-adjusted measure.
| Portfolio | $1 became | CAGR | Volatility | Sharpe (higher is better) | Deepest drawdown | Calmar (higher is better) |
|---|---|---|---|---|---|---|
| ETH | $14.48 | 50.6% | 79.6% | 0.88 | −78.8% | 0.64 |
| ETH 60/40 (60% ETH, 40% RiskOFF ETH) | $9.77 | 41.8% | 53.0% | 0.87 | −59.2% | 0.71 |
| BTC | $8.69 | 39.3% | 58.8% | 0.81 | −76.6% | 0.51 |
| BTC 60/40 (60% BTC, 40% RiskOFF BTC) | $5.44 | 29.6% | 40.1% | 0.78 | −61.5% | 0.48 |
| Classic 60/40 (60% S&P 500, 40% US bonds) | $1.82 | 9.7% | 12.8% | 0.56 | −21.6% | 0.45 |
Six and a half years of daily data, January 2020 through July 2026. CAGR and volatility are per year; cash for the Sharpe ratio is the 3-month US T-bill (mean 2.9%). Crypto rows use all calendar days; stock-and-bond rows use NYSE trading days.
The ETH 60/40 (60% ETH, 40% RiskOFF ETH) kept essentially the entire risk-adjusted score of the era’s best asset—0.87 against ETH’s 0.88—while the deepest fall shrank from −79% to −59% and the days worse than −5% fell from 177 to 78. The BTC 60/40 (60% BTC, 40% RiskOFF BTC) paid a visible toll—0.78 against BTC’s 0.81—in exchange for fifteen points less drawdown and 35 ugly days instead of 93. One got the safety free; one paid a fair price for it. Both beat the classic 60/40’s 0.56 by a distance.
A dial, not a trade-off
Forty percent is a convention, not a law. The ballast can be set anywhere from 0% to 100%, and every setting is a different portfolio, so the chart below plots them all. Reading it is simple: higher means faster growth, further left means a calmer ride.
Follow the ETH curve first. From pure ETH all the way down to 60% ballast, the Sharpe ratio never drops below 0.85—at every setting on that stretch you are paid just as well for each unit of risk—while the deepest fall shrinks from −79% to −47%. Turning the dial changes how much pain you take, not how well you are paid. That is why we call it a dial, not a trade-off. The BTC curve is more ordinary: each notch of ballast costs a sliver of score, from 0.81 with no ballast to 0.73 at 60%. The reason is mostly that RiskOFF BTC earned 8.2% a year over the window while RiskOFF ETH earned 11.9%, so ETH’s ballast pulls more of its own weight. The safety is real on both curves; on ETH it also came free.
The crash test
Averages hide the nights that matter. The table below takes the five worst crypto storms of the window and asks one question of each: from that storm’s peak to its bottom, how much did you lose? The answer repeats in every row: each 60/40 lost roughly a quarter to a third less than its raw asset, because RiskOFF’s floor held through every one of them. The classic 60/40 barely felt these storms—crypto crashes are not its weather.
The last row turns the question around. The classic recipe’s defining storm was 2022, the year stocks and bonds sank together—and this time the cause is well understood: inflation. To fight it, the Federal Reserve raised rates at the fastest pace in four decades, and rising rates cut the price of existing bonds by simple arithmetic while the same tightening dragged stocks down, so both sides of the recipe fell at once. The table measures that full 365-day year for every column; inside the window, the classic 60/40’s own fall ran from January to October—20.5% peak to trough, nearly as deep as its COVID crash, except COVID was over in weeks. The crypto 60/40s, crypto-sized as their falls were, still cut a quarter to a third off their raw assets’ declines. The ballast everyone expected to fail held; the ballast everyone expected to hold failed.
| Event | Days | BTC | BTC 60/40 | ETH | ETH 60/40 | Classic 60/40 |
|---|---|---|---|---|---|---|
| COVID crash, Mar 2020 | 46 | −52.4% | −37.4% | −60.3% | −42.3% | −21.6% |
| May 2021 cascade | 80 | −49.6% | −37.7% | −58.2% | −43.6% | −2.7% |
| LUNA collapse, May 2022 | 60 | −52.4% | −36.3% | −65.4% | −44.8% | −9.8% |
| FTX failure, Nov 2022 | 60 | −26.2% | −19.9% | −32.9% | −24.3% | −5.0% |
| Yen-carry unwind, Aug 2024 | 26 | −20.3% | −15.0% | −33.3% | −24.5% | −3.3% |
| 2022, stocks and bonds together | 365 | −66.9% | −50.4% | −73.6% | −52.8% | −20.5% |
Deepest peak-to-trough fall inside each event window; Days is the window’s length. BTC 60/40 = 60% BTC, 40% RiskOFF BTC; ETH 60/40 = 60% ETH, 40% RiskOFF ETH; both rebalanced monthly. The last row is the classic 60/40’s own worst storm, measured across the full year for every column.
The recovery race
Drawdowns are quoted in percent but lived in time, and time is where the ballast earns its keep most visibly. After the November 2021 peak, ETH spent 1,374 days underwater—its holders were not whole again until August 2025. The ETH 60/40 was whole by March 2024, 17 months earlier. It fell less to begin with, and through every month of the bear its calendar was mechanically selling ballast to buy more ETH at lower prices. On BTC the same race ended in a five-day tie—841 days for the 60/40 against 846 for BTC—which is its own honest lesson: the shallower the crash, the less the ballast has to do.
Against the original
The ladder below puts every portfolio and asset in this study on one scale: the Sharpe ratio. Gold is on it because gold is finance’s oldest ballast—the thing people have bought for centuries when they wanted weight that holds—and this window was quietly one of its great runs. That earns two honest concessions before the punchline. First, on the pain-adjusted Calmar score, gold (0.66) beat every raw asset and the BTC 60/40; only the ETH 60/40 scored higher (0.71). Second, the classic 60/40’s deepest fall, −21.6%, is far shallower than either crypto version’s: an investor who cannot stomach a −59% fall should not hold a crypto portfolio, ballast or no ballast.
What the ladder does establish is narrower, and still remarkable: per unit of risk taken, both crypto 60/40s beat the portfolio construct they borrowed the name from—0.87 and 0.78 against 0.56—over the same six years, on the same yardstick.
The other side
This is the fourth study in a series. In Risk Alpha: The 55% Threshold we measured the switch: rotating one position between RiskON—the ~2X token minted opposite RiskOFF—and RiskOFF as the market turns, where the backtests put the break-even at calling the market right roughly 55% of the time, barely better than a coin flip, for the switching to beat buy-and-hold. In The Leverage Tax we measured what crypto’s favorite offense actually costs: holding a 2X leveraged position through perpetual futures burns double-digit percentages a year in funding fees alone, and as a result RiskON, which pays no funding, vastly outperformed the 2X Perp—compounded through the bull markets since 2020, $1 grew to $53 against $18 on BTC and to $97 against $22 on ETH. In Calm Engineered we measured the defense: RiskOFF ran calmer than gold and the S&P 500 over the same six years. This study does the portfolio construction, doing the oldest job in finance: growth on one side, ballast on the other. As per our backtests, that construction kept nearly all of the era’s best risk-adjusted score on ETH, bought its calm at a fair price on BTC, and surfaced from the bear a year and a half sooner on the asset that needed it most.
Crypto did not need better coins. It needed ballast. The missing 40 finally has a design.
1 Daily returns for BTC, ETH, RiskOFF BTC, and RiskOFF ETH from The Risk Protocol’s pricing engine (net token value), chain-linked across epochs: 2,382 daily observations from 2019-12-31 through 2026-07-08.
2 S&P 500 (SPY) and US bonds (AGG, the Bloomberg US Aggregate ETF) as dividend-adjusted daily closes from Yahoo Finance; gold as the COMEX continuous front-month contract; cash as the 3-month US Treasury constant-maturity yield (FRED series DGS3MO). Crypto trades every day of the year and US markets do not; each series is scored on its own trading days, and re-scoring the crypto portfolios on NYSE days only moves their Sharpe ratios by at most a hundredth (0.87 and 0.77 against the classic’s 0.56).
3 RiskOFF is minted by splitting a BTC or ETH deposit into two tokens: RiskOFF keeps a floor under each epoch’s losses in exchange for a cap on its gains, and the balance of the exposure goes to the other token in the pair. Its behavior over these six years—volatility below gold’s and the S&P 500’s—is measured in Calm Engineered.
4 Bloomberg US Aggregate total return of roughly −13% in 2022, the worst calendar year in the index family’s history and, per Charlie Bilello’s long-run series as cited by The Motley Fool, the worst year for US bonds since 1937.
5 All portfolio results are backtests on engine net token values; live results would also reflect execution, gas, and slippage. Trading costs barely move the result: charging 25 basis points on every rebalance trade shifts the ETH 60/40’s ending value from $9.77 to $9.70 and the BTC 60/40’s from $5.44 to $5.41.
