Ask a financial adviser anywhere in the world for a sensible portfolio and you will hear the same recipe: 60% stocks, 40% bonds. The 60 does the growing. The 40 is ballast—an asset that is supposed to hold steady, earn something, and rise when stocks fall, so that the whole portfolio never sinks as far as its riskiest part. That recipe, the 60/40, has been the benchmark for balanced investing for roughly fifty years.
Crypto copied the 60 and never built the 40. BTC and ETH turned out to be two of the great growth assets of the era, but every candidate for ballast beside them has failed the audition: the major alternative coins move nearly in lockstep with BTC, and stablecoins hold their price by going nowhere at all. A crypto portfolio has effectively been 100/0 since the day it existed. Over the last six years, for the first time, there is enough data to ask what happens when crypto gets a real 40.
How we measured it
The token numbers in this article come from our own pricing engine: daily returns for RiskOFF and the BTC and ETH prices it is struck against, from the end of 2019 to July 2026—the last six years, covering COVID, the 2021 mania, the 2022 unwind, two full cycles1. The traditional side uses total-return index funds as stand-ins: SPY for the S&P 500 and AGG for the US bond market, both with dividends included, plus gold futures and 3-month US Treasury bills—the standard stand-in for cash2. Every portfolio in this study follows one dumb rule: hold the target weights, and once a month sell a little of whichever side has drifted above its target and buy the side that has drifted below. That is rebalancing—no forecasts, no signals, a calendar. Nothing is cherry-picked: every day is in the sample, crashes included.
The job description of a 40
Ballast has three duties. It must hold its value on its own. It must not crash at the same time as the growth half—which is why the classic 40 is judged on correlation, a number between −1 and +1 measuring how much two assets move together, where ballast wants to live near zero or below. And it must give rebalancing something to push against: when the growth half doubles, the discipline of trimming it and topping up the calm half is what turns volatility into return instead of regret.
Notice that the second duty is an assumption, not a law. Bonds do not cushion stock crashes by contract; they usually have, in the specific economic weather of the last few decades. The 60/40 quietly bets that the weather holds.
The year the ballast sank
In 2022 the weather changed. Inflation forced interest rates up, and rising rates hurt stocks and bonds at the same time: the S&P 500 fell 18% that year and the US bond market fell 13%. The classic 60/40 lost 15.8%—by most long-run tallies its worst calendar year since 19373. The one thing the 40 exists to do, it did not do.
Stretch the lens across our whole window and the picture is worse than one bad year. Over the last six years the classic 40 returned 0.8% a year while cash paid 2.9%. On the standard score for this—the Sharpe ratio, which takes what an investment earned above cash and divides it by its volatility (how widely its daily returns swing, scaled to a yearly figure), so that higher is better and zero means cash did just as well—US bonds scored −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 to put beside the growth. The obvious candidates fail on the first two duties. Every major alternative coin is, statistically, the same trade as BTC wearing a different logo: over the last six years their daily moves ran 0.42 to 0.82 correlated with BTC’s, and the ones at the low end of that range earn their independence through chaos rather than calm—DOGE’s single best day in the window was +308%. Stablecoins pass the do-not-crash test by holding a price of exactly $1 forever, which means they fail the earn-something test by design: they are cash, and cash is what the classic 40 just spent six years losing to.
This is the gap RiskOFF was built for. RiskOFF is the defensive half of our split of BTC and ETH: every epoch it carries a floor about 5% below the starting price and a cap about 8% above, a band paid for structurally—the upside given away past the cap funds the protection below the floor4. In Calm Engineered we measured the result: volatility of 15.6% on BTC and 16.8% on ETH over the last six years—below gold and below the S&P 500. And unlike bonds, its protection makes no bet on correlation weather: the floor is a property of the structure, not of the economic regime. It holds its value, it earns, and it cannot crash with the 60 by more than its band allows. That is a job application for the 40.
The first crypto 60/40
So we built the portfolio crypto never had. Sixty cents of every dollar goes to the growth half, split equally between BTC and ETH. Forty cents goes to the ballast, split equally between RiskOFF BTC and RiskOFF ETH. Once a month, rebalance5. Over the last six years that meant 78 rebalances: 43 of them trimmed the growth half after it ran, 35 added to it after it fell, and the median trade moved just 3.1% of the portfolio. Here is what came out, with two yardsticks defined as they appear: CAGR, the compound annual growth rate, is the steady yearly growth that turns the starting dollar into the ending value; Calmar is that growth divided by the deepest drawdown—the fall from a peak to the lowest point after it—so it measures how much growth an asset delivers per unit of worst pain.
| Portfolio / asset | $1 grew to | CAGR | Volatility | Sharpe | Deepest drawdown | Calmar | Worst day |
|---|---|---|---|---|---|---|---|
| The crypto 60/40 | $8.03 | 37.6% | 44.6% | 0.88 | −58.0% | 0.65 | −19.3% |
| BTC-only version | $5.44 | 29.6% | 40.1% | 0.78 | −61.5% | 0.48 | −17.2% |
| ETH-only version | $9.77 | 41.8% | 53.0% | 0.87 | −59.2% | 0.71 | −21.4% |
| BTC | $8.69 | 39.3% | 58.8% | 0.81 | −76.6% | 0.51 | −27.1% |
| ETH | $14.48 | 50.6% | 79.6% | 0.88 | −78.8% | 0.64 | −34.7% |
| RiskOFF BTC | $1.68 | 8.2% | 15.6% | 0.40 | −33.6% | 0.25 | −5.8% |
| RiskOFF ETH | $2.08 | 11.9% | 16.8% | 0.58 | −31.6% | 0.38 | −5.2% |
| Classic 60/40 (S&P 500 + bonds) | $1.82 | 9.7% | 12.8% | 0.56 | −21.6% | 0.45 | −7.2% |
The last six years, daily data, monthly rebalancing. Sharpe: return above cash per unit of volatility (higher is better). Calmar: yearly growth per unit of deepest drawdown (higher is better). The crypto 60/40 is 30% BTC, 30% ETH, 20% RiskOFF BTC, 20% RiskOFF ETH.
As per our backtests, $1 in the crypto 60/40 grew to $8.03 at a Sharpe ratio of 0.88—the same risk-adjusted score as ETH, the best single asset of the era—while its deepest drawdown was −58% against ETH’s −79%.
Read the table once more. The 60/40 gave up meaningful raw growth against pure ETH—$8.03 versus $14.48—but it matched it per unit of risk, beat everything on the page per unit of worst pain except gold, cut the worst single day from −35% to −19%, and suffered 44 days worse than −5% where ETH suffered 177. That is exactly the trade the classic 60/40 has sold for fifty years—except this one still grew at 37.6% a year.
A dial, not a trade-off
Forty percent is a convention, not a law of nature. Slide the ballast weight anywhere from 0 to 100 and each blend is a different portfolio; plotting them all gives the curve below—up is more growth, left is less volatility. Two things stand out. The curves bow left: the first slices of RiskOFF remove volatility much faster than they remove growth. And on ETH the Sharpe ratio barely moves—it stays at 0.85 or better from pure ETH all the way to a 60% RiskOFF weight, while the deepest drawdown improves from −79% to −47%. Within that whole range, the ballast is nearly free on a risk-adjusted basis: it changes how much pain you take, not how well you are paid per unit of risk.
The crash test
Averages can hide what a crisis feels like, so here is the house tradition: the five worst market events of the window, and the deepest fall inside each one.
| Event | BTC | BTC 60/40 | ETH | ETH 60/40 | Crypto 60/40 | Classic 60/40 |
|---|---|---|---|---|---|---|
| COVID crash, Mar 2020 (46 days) | −52.4% | −37.4% | −60.3% | −42.3% | −39.9% | −21.6% |
| May 2021 cascade (80 days) | −49.6% | −37.7% | −58.2% | −43.6% | −39.4% | −2.7% |
| LUNA collapse, May 2022 (60 days) | −52.4% | −36.3% | −65.4% | −44.8% | −40.4% | −9.8% |
| FTX failure, Nov 2022 (60 days) | −26.2% | −19.9% | −32.9% | −24.3% | −21.9% | −5.0% |
| Yen-carry unwind, Aug 2024 (26 days) | −20.3% | −15.0% | −33.3% | −24.5% | −19.0% | −3.3% |
Peak-to-trough inside each window, daily closes. The 60/40 columns pair each asset (or both) with RiskOFF at a 40% weight, rebalanced monthly.
The pattern repeats in every row: the crypto 60/40 cut each crash roughly by a third against the raw assets. The classic 60/40 fell least in the macro events—that is what a mature, low-volatility portfolio does—but recall that its own worst event of the era, 2022, is not on this list because it was not a crypto crash: it was the year its ballast failed. The crypto 60/40’s ballast held its band in all five.
The recovery race
Drawdowns are quoted in percent but lived in time, and this is where the 40 earns its keep most visibly. After the 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, because it fell less and because every month of the bear it was mechanically topping up the growth half at lower prices. On BTC the race was a near tie; the shallower the crash, the less the 40 has to do.
Against the original
Put everything on one ruler and the six-year league table reads as follows.
| Portfolio / asset | Sharpe | Calmar | $1 grew to | Deepest drawdown |
|---|---|---|---|---|
| The crypto 60/40 | 0.88 | 0.65 | $8.03 | −58.0% |
| ETH | 0.88 | 0.64 | $14.48 | −78.8% |
| BTC | 0.81 | 0.51 | $8.69 | −76.6% |
| Gold | 0.74 | 0.66 | $2.68 | −25.0% |
| S&P 500 | 0.67 | 0.46 | $2.54 | −33.7% |
| Classic 60/40 | 0.56 | 0.45 | $1.82 | −21.6% |
| US bonds (the classic 40) | -0.30 | 0.04 | $1.05 | −18.4% |
Sorted by Sharpe ratio. Same window, same conventions throughout; the ordering is unchanged when every series is sampled on shared trading days2.
Honesty requires two concessions here. Gold—quietly one of the great assets of this window—matched the crypto 60/40 on Calmar, though with less than half the growth rate. And the classic 60/40’s deepest drawdown, −21.6%, is far shallower than the crypto version’s −58%: an investor who cannot tolerate a crypto-sized drawdown should not hold a crypto portfolio, 40 or no 40. What the comparison does establish is narrower and still remarkable: measured per unit of risk taken, the first crypto 60/40 beat the portfolio construct it borrowed its name from—0.88 against 0.56—in the same six years.
What the 40 does not do
We want to be precise about the limits, because they are part of the result.
- It does not diversify; it de-risks. RiskOFF runs 0.77 correlated to its underlying asset—it is carved from the same coin, so it dampens the same move rather than zigging when the 60 zags. The flip side: it makes no correlation bet. The thing that broke the classic 40 in 2022—a regime change flipping a friendly correlation hostile—has no analogue here, because the floor is structural4.
- It does not make crypto mild. A −58% drawdown is still crypto-sized. The 40 turns a catastrophic ride into a survivable one; it does not turn BTC into a bond.
- On BTC alone, the dial is fair rather than free. The BTC-only 60/40 scored 0.78 against BTC’s 0.81—pain relief at roughly fair price. The ETH version and the two-asset version are where the ballast came free.
- The usual assumptions apply. Results are gross of protocol fees, rebalancing is assumed at NTV, and the study is a backtest over one six-year stretch of history5. The structure needs live, battle-tested markets before anyone should treat these numbers as a promise.
The other half
In The Leverage Tax we measured what crypto’s favorite offense actually costs. In Calm Engineered we measured the calm that crypto never had. This study puts the two findings in one portfolio and lets them do the oldest job in finance: growth on one side, ballast on the other, a calendar in between. Over the last six years, that portfolio matched the era’s best asset per unit of risk, beat the construct it was named after, and came back from the bear a year and a half sooner than its own growth engine.
Crypto did not need better coins. It needed the other half. The 40 is not missing anymore.
1 Token figures use each token’s daily returns as our own pricing engine computes them—marked daily, re-struck at each epoch, chain-linked across epoch resets so re-pricing never counts as a gain or a loss—the same canonical series as Calm Engineered. NTV, each token’s Net Token Value, is built exactly as the protocol prices it. Results are computed before any protocol fees.
2 S&P 500 and US bonds are represented by the SPY and AGG exchange-traded funds with dividends reinvested (Yahoo Finance adjusted closes), gold by front-month futures, and cash by the 3-month US Treasury bill rate (FRED), which averaged 2.9% a year over the window. Crypto series run on a 365-day calendar and traditional series on their 252-trading-day calendar, each annualized on its own; re-running everything on shared NYSE trading days leaves the ordering unchanged (crypto 60/40 Sharpe 0.87 versus 0.56 for the classic).
3 Several long-run tallies—among them Charlie Bilello’s data as reported by The Motley Fool—place 2022 as the 60/40’s worst calendar year since 1937, with US stocks and 10-year Treasuries both down double digits for the first time in modern records. The −15.8% figure in this article is our own computation: dividend-adjusted SPY and AGG at 60/40 weights, rebalanced monthly.
4 RiskOFF’s floor is fixed at −5% per epoch; the upside cap is set afresh each epoch so that the collar prices to zero—the premium for the surrendered upside exactly funds the protection. The full risk profile, including how the floor behaved through every crash of the last six years and what a knock-out barrier is, is measured in Calm Engineered.
5 Rebalancing trades are assumed to execute at NTV; a listed market price can trade around it. The result is not sensitive to reasonable frictions or scheduling: charging 25 basis points per rebalance moves the ending value from $8.03 to $7.98, and every rebalancing cadence from weekly to annual beats never rebalancing on both Sharpe and drawdown, as per our backtests.
