Many shares have performed very well recently. But where there has been nothing but upward movement for a long time, there will also be setbacks at some point. The market is currently reacting sensitively - even minor news leads to significant movements. One example is the recent concerns about the credit quality of smaller US regional banks, which triggered noticeable price losses yesterday and today.

This also raises the question of whether commodities could play a greater role again in the future - not as a substitute, but as part of a broader diversification. Especially in phases when stock markets react nervously, commodities can provide a tactical counterweight. This consideration gave rise to the idea of trading them systematically - not through emotion, but through rules.

The inspiration came from a natural gas trade that @Epi had presented. It was less exciting because of the result than because of the underlying dynamics. How can something like this be mapped using rules? When does momentum arise, when is a trend sustainable - and when does it end?

This is how the commodity rotation approach came about - an attempt to understand the movements of the commodity markets with technical discipline. The approach consistently relies on momentum: it does not aim to guess the bottom, but to accompany the strength. I have not yet tried it out in practice. But the structure is in place and it shows how a tactical, signal-based commodity approach can be constructed.

Commodities rarely move evenly. They move in waves, driven by demand, inventories, politics and currency. These movements are hardly predictable - but they are measurable. The approach therefore views the market as a rotating playing field: energy, metals, agriculture - capital constantly moves between these segments. The aim is not to predict where the next impulse will come from, but to invest where the trend is already visible. Only the strongest commodity counts - the rest is left out.

The universe comprises nine liquid underlying ETFs that can be traded via WisdomTree. Each represents its own cycle, together they form the entire spectrum of the global commodities market:

• $PHGP (-0,21%) (Gold) - anchor of stability during periods of high uncertainty, typical counterbalance to risk assets.
• $PHAG (-3,32%) (Silver) - more volatile than gold, with an industrial component, strong in bull phases.
• $CRUD (+0,52%) (WTI oil) - central energy source, sensitive to OPEC policy and the economy.
• $NGAS (+0,67%) (Natural gas) - highly volatile, weather and storage-driven, with high momentum in bottleneck phases.
• $COPA (-9,16%) (copper) - leading indicator of the global economy, benefits from electrification and infrastructure.
• $PHPT (-3,89%) (Platinum) - Precious metal with industrial significance, for example in the automotive and hydrogen industries.
• $WEAT (-2,22%) (Wheat) - cyclical and weather-dependent, represents the agricultural sector.
• $CORN (-2,41%) (Corn) - basic raw material for food and energy production, often parallel to oil and agricultural trends.
• $COFF (-1,5%) (Coffee) - seasonal market with strong price fluctuations, influenced by climate and currencies.

Energy, industry, precious metals and agriculture are thus fully covered - without overlaps, but with sufficient breadth to make rotation visible.

The approach follows a fixed process that is reviewed weekly. A commodity is only included if its six-month performance is positive. It is only considered eligible for activation above one percent. This is followed by the trend check: the price must be above the GD50 and the short-term average (GD20) must exceed the GD50. Only then is the trend considered confirmed. The RSI serves as a control variable. Values between 50 and 70 signal stability, above 75 overheating, below 40 weakness. If the RSI rises too sharply or falls significantly, the approach reacts automatically: overheated movements are reduced, broken trends are sold.

The strength of the trend determines the leverage. If the six-month performance is over 10 %, a triple-leveraged ETF may be used. Between 5 % and 10 %, the 2× variant is used. Below this, the basic ETF is traded - the risk increases with the strength of the trend, not with your gut feeling.

The loss limitation is also clearly regulated. With the 1× variant, the exit takes place at a loss of more than 5 %, with 2× from 10 %, with 3× from 15 %. This means that the maximum risk per position remains constant. Profit protection takes place in two stages. If the RSI rises above 75 or the price falls below the GD50, half of the position is sold, while the rest continues to run as long as the long-term trend (GD50 > GD200) remains intact. If the price falls below GD200, the entire position is sold.

All signals are re-evaluated on a weekly basis. If another commodity outperforms in the ranking, an exit is also made - the position is rotated. The approach never holds more than one position at a time.

For a better overview, the rules can also be summarized in a condensed form:

• Momentum: Only active commodities with a positive six-month performance (> 1 %).
• Trend structure: Price > GD50 and GD20 > GD50 as a prerequisite for long signals.
• RSI filter: Entry only at 50 < RSI < 70; above 75 partial sell, below 40 sell.
• Leverage control: performance > 10 % → 3× ETF; 5-10 % → 2× ETF; < 5 % → basis.
• Stop loss: - 5 % (1×), - 10 % (2×), - 15 % (3×).
• Take profit 1: RSI > 75 or price < GD50 → 50 % Verkauf, Rest halten bei GD50 > GD200.
• Take profit 2: Price < GD200 → complete sell.
• Rotation: Weekly re-evaluation - in the event of a stronger commodity or violation of one of the rules → exit and switch.

This summary shows that the approach does not rely on intuition, but on clear, repeatable decision-making logic. It is not about the perfect forecast, but about reacting consistently - that is the core of every momentum strategy.

It is easy to see how this works in practice. Climbs $CRUD (+0,52%) rises to a six-month performance of +12 %, GD20 > GD50, RSI = 63, the entry is made via the 3× ETF. If the RSI later rises above 75, half is sold. If the price falls below GD200, the complete exit follows. Or: If another commodity in the weekly ranking, such as $COPA (-9,16%) (copper), provides stronger signals, a switch is also made. In this way, the approach remains flexible, but consistently rule-based.

The commodity rotation approach is not a rigid trading system, but an attempt to bring structure to the volatility of the commodity markets. It defines when an entry is justified, how much leverage is allowed, when profits should be secured and when to consistently exit - be it through a trend break or through relative weakness compared to the rest of the universe.

I have not yet put this approach into practice. But developments have already shown how helpful it can be to replace emotions with rules. Whether it proves itself in practice remains to be seen.

What do you think of the approach?

Are raw materials missing - or could some be removed?

What do you think of the rules - are they plausible?

Let's discuss this idea.

Sometimes it's worth taking a fresh look at the familiar - I'd like to share some new insights here and look forward to hearing your opinions on the subject:

Gold has been the subject of much discussion on the financial markets recently - and rightly so. In the current year 2025, the precious metal is one of the top performers: The spot price has risen by around 38-40% in USD terms since the start of the year, while global share indices have risen significantly less in the same period. According to the World Gold Council, gold was already up around +26% YTD by the middle of the year - a figure that had risen further to over +40% by September. By comparison, global equity ETFs were up ~+17% YTD (in USD) at mid-year. Gold marked new all-time highs around $3,700/oz.

What is driving this gold boom?

Several macroeconomic factors are at play. Firstly, a weaker US dollar in 2025 has boosted the price of gold, as gold is quoted in dollars. Secondly, there is still uncertainty in the geopolitical environment - from the ongoing war in Ukraine to trade conflicts - which is driving investors into safe havens. Added to this are concerns about inflation and recession, which are also increasing the attractiveness of gold as a store of value.

The demand from institutional investors is particularly noteworthy: central banks around the world are increasing their gold reserves more than they have for a long time. Since 2022, central banks have been buying over 1,000 tons of gold every year - around twice as much as the average in previous years. These record-high central bank purchases and continued inflows into gold ETFs are seen as the main drivers of the rally. At the same time, expectations of falling US interest rates (after the high interest rates of previous years) have reduced the opportunity cost of gold and sparked additional demand.

Gold in the portfolio: Diversification vs. "insurance"

Gold is a polarizing topic in many investor portfolios - often either not present at all or very highly weighted. Gold is traditionally seen as a "safe haven" and inflation protection. In fact, history shows that gold tends to rise, especially in times of crisis, when stock markets are weak. Gold recorded positive returns in 15 of the 20 worst quarters of the S&P 500 and outperformed equities in almost all other cases. This defensive characteristic makes it a stabilizer in many portfolios.

Even more important, however, is the diversification effect: gold has a relatively low or even negative correlation to traditional investments such as equities and bonds. In normal market phases, gold behaves independently and often in the opposite direction to share prices. This can help to reduce the fluctuation range of the overall portfolio - gold therefore does not "run" in step with the stock market indices.

Studies show that even a small addition of gold can measurably reduce portfolio risks: In one analysis, the Sharpe ratio (risk-return ratio) of an insurer's portfolio rose by around +12% when 2.5% gold was added. In other words, gold can improve the risk/return profile due to its low correlation. It is therefore no wonder that some asset managers recommend a gold allocation of ~10% in a balanced portfolio. Asset manager Sprott, for example, is of the opinion that ~10% physical gold (possibly supplemented by up to 5% in mining stocks) is a sensible component for risk diversification.

At the same time, gold should not be blindly idealized: Gold is not a perfect insurance policy for all eventualities. Like all investments, it is subject to fluctuations in value - sometimes considerable ones. For example, the price of gold lost around 29% of its value in 2013-2014 when the US Federal Reserve scaled back its ultra-loose monetary policy. Such drawdowns show that gold investors have to ride out lean periods.

In addition, gold does not generate any current income (no interest or dividends). In calm market phases, opportunity costs can therefore arise if, for example, bonds yield interest and gold is "only" unchanged. Some professionals - such as life insurers - argue that gold does not fit into the concept because no cash flow is generated.

Ultimately, it all comes down to perspective: Gold is less suitable for generating regular income, but more as a strategic asset component for extreme cases ("tail hedge") and for admixing with its own dynamic profile.

Personally, I take a middle course with gold.

Gold ETCs make up around 5-10% of my portfolio - not because I consider it to be the ultimate crash insurance, but as a deliberate counterbalance to equities and crypto. My aim is to have a share that develops independently of my equity investments and tends to be more stable or even positive in phases when equities and cryptocurrencies weaken. This strategy reflects what gold means for many investors: a diversifier and "crisis cushion", but not a sure-fire success.

It is interesting to note that gold and equities do not always move in opposite directions. The most recent example: In the first half of the 2020s, both gold and many stock markets recorded strong gains at the same time. Investors should therefore be aware that the correlation between gold and other assets can vary.

In phases of global booms (with simultaneously rising corporate profits and inflation), gold can certainly rise with equities. Conversely, in acute moments of panic, gold can also be sold off in the short term before it reasserts itself as a safe haven (as seen in March 2020, for example).

However, the overall picture remains: over longer periods, gold has its own price determination, driven by macro factors (inflation, real interest rates, USD exchange rate, geopolitical risks) and supply/demand (jewelry industry, investor demand, mining production). These factors are fundamentally different from equities and ensure that gold usually lives up to its reputation as a portfolio stabilizer.

Short-term fluctuation vs. long term: performance over time

What about long-term performance? Opinions are often divided here. In the long term - over many decades - gold has offered real value preservation plus a moderate increase in value, while equities (including dividends) have grown much more strongly.

An often-cited example: If one had invested $100 each in gold and the S&P 500 stock index since 1971 (the end of Bretton Woods and the freeing of the gold price), the gold investment would be around $7,000 today, but the stock investment would be over $26,000 (with dividend reinvestment). So over ~50 years, the stock market has delivered the higher growth.

But - and this is important - the answer depends heavily on the period under consideration. Anyone who started with gold and equities in 2000 has an advantage with gold today: $100 would have become ~$900 with gold, while $100 in the S&P 500 (well doubled despite the dotcom and financial crisis) grew to around $600.

The period 2000-2024 was characterized by two severe bear markets in equities and at the same time a major upswing in the price of gold. There were similar "catch-up runs" for gold in the 1970s: in the stagflation of that era, gold shot up massively while equities ran sideways.

What can we learn from this?

Timing and time horizon are crucial. Gold moves in long cycles. Phases of rapid rises (as recently since 2019) can follow longer lulls (think of the 1980s/90s, when gold barely moved for two decades).

• Over 10-20 years, gold can certainly keep pace with or outperform equities, especially if the starting period came from a low phase in the gold price.
• Since the turn of the millennium (1999-2024), for example, gold has returned an average of around +9.2% per year, outperforming global equities.
• Over 30+ years, on the other hand, broad equity indices are generally ahead, especially when dividends are taken into account.

Nevertheless, gold has also returned in real terms - since 1971 on average around +8 % p.a. in USD, which is well above inflation. This means that the often-heard criticism that gold "only preserves purchasing power but has no return" is not entirely fair - the real value of gold has also grown significantly over the decades.

It just depends on the chosen starting and end point. In terms of diversification, this means that gold can generate returns in certain phases and compensate for any losses in other asset classes, but you should not expect it to outperform equities on an ongoing basis.

The bottom line is that gold remains a special building block in the investment universe:

It is a commodity and currency substitute with its own supply/demand dynamics, not a productive investment in the traditional sense, but historically a reliable store of value over generations.

Particularly in an environment in which equities and bonds are again correlating positively at times (e.g. with simultaneous losses in 2022), gold is gaining in importance as an independent diversifier. Whether you hold 0%, 5% or 20% gold depends on your individual convictions, goals and risk preferences.
