The Truth Everyone Pretends to Know
Ask anyone: “Is there a relationship between risk and return?” The answer will always be yes. Of course there is. Everyone knows it. It is the basic concept of finance.
Then look at what that same person does with their money. They look for a guaranteed 5% return. They complain that their savings account pays too little. They buy the product that “returned 20% last year” without asking why. They flee equities after a 15% decline, swearing they will never go back.
In practice: everyone knows the relationship between risk and return. No one respects it.
The human brain is programmed to avoid danger and seek rewards. In finance, this translates into the impossible search for high returns without risk. The El Dorado of investing, which, like its geographical counterpart, does not exist.
(Spoiler: every time someone tells you they have found it, you are about to lose money. Every single time.)
A Simple Relationship the Brain Rejects
The relationship between risk and return is one of the fundamental laws of finance. It is easy to state, but impossible to respect once emotions enter the picture.
It works like this.
Do you want higher returns? You have to accept more volatility, more uncertainty, and more nights when your portfolio is in the red. Do you want to sleep peacefully? You have to accept lower returns, eroding purchasing power, and life goals moving further away.
There is no third option. There is no magic product. There is no perfect moment. There is no genius who has discovered how to obtain equity-market returns with the risk level of a checking account.
Historical figures speak with disarming clarity:
| Asset class | Average annual real return (long term) | Typical maximum drawdown |
|---|---|---|
| Global equities (MSCI World) | ~5–7% | −30% / −50% every 5–10 years |
| Investment-grade bonds | ~1–2% | −10% / −15% |
| Cash / Savings accounts | ~0% (often negative after inflation) | No nominal loss, but constant erosion |
The table says it all. Global equities deliver 5–7% in real terms over the long term, but the entry price is drawdowns of 30–50% that arrive with brutal regularity. Bonds deliver 1–2% in real terms with limited fluctuations. Cash delivers no real return; in fact, with inflation, you lose purchasing power every day.
There is no free lunch. Ever.
And here comes the point that no one in Italy wants to hear: according to the Intesa SanPaolo–Centro Einaudi survey, 9 out of 10 Italian savers declare an absolute aversion to risk, with security as their primary objective. Only 6.7% cite long-term returns as a priority.
The result is predictable: an entire country parking its savings in instruments that protect them nominally while destroying them in real terms. Year after year, silently, without alarms or notifications.
Why the Risk Premium Exists
The Mathematics of Losses (and Why the Brain Gets It Wrong)
Jason Zweig constructed a table that every investor should tattoo on the hand they use to click “sell”:
| Loss incurred | Return needed to recover |
|---|---|
| −10% | +11.1% |
| −25% | +33.3% |
| −50% | +100% |
| −75% | +300% |
| −95% | +1,900% |
The table appears to argue for caution: the more you lose, the harder it becomes to recover. And the brain interprets it exactly that way, as a warning not to take risks.
But that is the wrong interpretation. Because the right question is not, “How much do I have to recover after a loss?” The right question is: “How much does it cost me never to have participated in the rise?”
(Loss aversion—the tendency to feel losses roughly twice as strongly as equivalent gains—is the bug in the human operating system. Kahneman and Tversky demonstrated it in the 1970s. Fifty years later, the bug is still there. It does not update.)
The Premium Exists Because People Are Afraid
Here is the most important paradox in all of finance: the equity risk premium exists precisely because people are afraid to accept it.
If everyone were perfectly rational and capable of tolerating volatility without flinching, stocks would not need to return more than bonds to attract capital. The risk premium would disappear.
But people are not rational. They sell in a panic. They buy in euphoria. They flee after a 20% decline and return after a 30% rise. And every time they do so, they give returns to those who remain invested.
Morgan Housel summed it up perfectly in Investment Law #5: “Luck and risk are opposite sides of the same coin, but we treat them very differently.” Risk is seen as something that happens to us; luck as something we caused ourselves.
Josh Brown quantified the cost of this irrationality: an investor who sold the S&P 500 at every 5% decline and re-entered after a 1% rebound would have achieved an annual return of just 2.8%. They transformed an equity portfolio into a bond portfolio, giving up decades of compounded returns for the privilege of “feeling safe” at the wrong moments.
And the most brutal statistic: less than 20% of 5% declines turned into a genuine bear market. 80% of the time, it was a false alarm. Those who sold were running from ghosts four times out of five.
The Safety Paradox
Here we reach the point that few have the courage to state clearly: being too cautious is a guarantee of underperformance.
It is not an opinion. It is arithmetic.
If your life goals require a real return of 5% per year—and for most people with a 20–30-year horizon, that is exactly what is needed—and you are invested in Italian government bonds and savings accounts returning 1% in real terms at best, you are not “playing it safe.” You are guaranteeing the failure of your financial plan.
The “safety” you are seeking does not protect you. It condemns you.
Historical MSCI World data confirms this with almost embarrassing regularity: over horizons of 15 years or more, negative returns are virtually absent. Global equities have produced positive returns in almost all 15-year periods since 1969. Positive versus negative years over the same time span: 34 to 12.
The long term works. But only for those with the courage—and the structure—to stay invested.
How to Manage the Risk–Return Relationship
Knowing that risk and return are inseparable is necessary. Knowing what to do with that knowledge is another matter. Here is how to translate the concept into real decisions.
1. Stop Looking for a “High Guaranteed Return”
It does not exist. If someone offers you one, there are only two possibilities: either they are lying, or the risk is hidden where you cannot see it. Capital-protected insurance policies with annual costs of 3%? The risk lies in the costs that consume the return. Structured funds with “90% protection”? The risk lies in the complexity you do not understand and the fees you do not see.
In finance, when something seems too good to be true, it always is. Without exception.
2. Define the Risk You Need (Not Just the Risk You Can Tolerate)
The MiFID questionnaire measures how much risk you can tolerate emotionally. It is useful, but it is only one-third of the story. The crucial question is: how much risk must you take on to achieve your goals?
If the required return calls for a 70% equity allocation and you have 20%, you are not being cautious. You are sabotaging your future. Build an asset allocation that reflects not only your fears, but also your goals.
3. Use Time as an Ally (Not as an Excuse)
Volatility—the 20%, 30%, and 50% declines—is the entry price for equity returns. But that price is amortized over time. Over one year, the stock market is a gamble. Over 15 years, it is almost a certainty.
Your task is not to eliminate volatility. It is to make sure you have enough time to endure it.
4. Do Not Confuse Risk with Volatility
Volatility is the price. The real risk is failing to achieve your life goals. They are two different things. A portfolio that fluctuates by 20% a year but grows by 7% in real terms over the long term is less risky for your goals than a savings account that never fluctuates but returns nothing.
The stock market is volatile. It is not risky for someone who has a plan, a time horizon, and the discipline to follow them. It is extremely risky for someone who has none of the three.
(To avoid the seven mental errors that sabotage even the best plans, and to avoid panic selling, you need a process. Not a product.)
The Sentence to Remember
The risk is not the enemy of return. It is the entry price. Those unwilling to pay it have no right to complain about the ticket.
Risk is not the enemy of return. It is the entry price. Those unwilling to pay it have no right to complain about the ticket.
Risk and return are inseparable. Like the two sides of a coin, like cost and value, like effort and results. You cannot have one without the other. And every time someone promises you the opposite—high return, zero risk—they are selling you an illusion.
The good news is that the price of risk is known, documented, and manageable. Global equity markets have rewarded those who had the patience and discipline to remain invested for sufficiently long horizons. Not always, not every year, and not without moments of panic. But over the long term, with a consistency that should reassure anyone with a plan.
The real risk is not investing. The real risk is failing to invest and discovering twenty years from now that your “security” cost you everything.

FAQ
What is meant by the risk–return relationship?
The risk–return relationship is the fundamental principle of finance according to which higher returns are possible only by accepting higher levels of risk—volatility and the possibility of loss. Global equities have historically returned 5–7% in real terms annually, but with drawdowns of 30–50% every 5–10 years. Bonds return 1–2% in real terms with limited fluctuations. Cash produces no real return. There is no investment that offers high returns without risk—and anyone who proposes one is hiding something.
Is there a high-return investment without risk?
No. It does not exist and cannot exist. If an investment offered high returns without risk, everyone would buy it, its price would rise, and its return would fall until it reflected the actual risk—that is, close to zero. When someone offers a high “guaranteed return,” there are two possibilities: either the risk is hidden—in the costs, complexity, or limited liquidity—or it is a scam. The equity risk premium exists precisely because volatility scares most people away from the market.
How much volatility must I accept to achieve good returns?
It depends on your goals and time horizon. To achieve a real annual return of 5–7%—typical of global equities—you must accept declines of 20–30% as a normal occurrence and occasional drawdowns of 40–50% during major crises. The key is time: over horizons of 15 years or more, the MSCI World has produced positive returns in almost all historical periods. Volatility is the entry price for returns, but that price is amortized through patience. Anyone with a short horizon—under five years—should significantly reduce their equity allocation.
Why do Italians invest too little in equities?
The Intesa SanPaolo–Centro Einaudi survey reveals that 9 out of 10 Italian savers declare an absolute aversion to risk. Only 6.7% cite long-term returns as their primary objective. This results in portfolios dominated by cash, Italian government bonds, and “capital-protected” products that return little or nothing after inflation and costs. The causes are multiple: low financial literacy, loss aversion amplified by the culture of the “safe home,” and a traditional financial industry that has an interest in selling expensive conservative products rather than low-cost, evidence-based solutions. The result is a paradox: by seeking safety, Italians condemn themselves to long-term underperformance.
