Copper prices surge 30%, can this rally still be chased?
In the past two months, copper prices have risen by 17%, and the stock price of Freeport-McMoRan (FCX), the leading international copper miner, has increased by 30% in just a month and a half. Is this rise in copper stocks a short-term hype or a long-term trend? To answer this question, we must first understand the operational logic of the copper industry chain.
From mine to end-use application, copper goes through three stages: mining, smelting, and processing. In this industry chain, companies at different positions react very differently to copper price changes—some profit immensely, while others get trapped. Only by understanding this can we accurately assess the investment opportunities in copper stocks.
Copper Industry Chain Deep Dive: Who Are the Real Winners?
Upstream mining companies: The higher the copper price, the thicker the profit
Upstream copper companies involved in mining and selling copper see their profits directly increase as copper prices rise. High industry concentration means larger companies are more likely to monopolize pricing power and secure a bigger share.

As the world's largest capital market, the US stock market's performance influences the nerves of global investors. However, many novice investors face a question: which index should they look at for the US stock market? In fact, unlike Taiwan's stock market, which only has the Weighted Index, the US has multiple major indices, each with its own characteristics, representing different aspects of the market.
Why does the US stock market need multiple major indices?
Before delving into the four major US indices, it's important to understand a core concept: the role of a market index is to reflect the overall market condition. However, the US stock market is large and has numerous listed companies, so a single index cannot fully capture the entire market's landscape. Therefore, different indices have emerged, each presenting the health of the US stock market from different angles.
For example, Japan uses the Nikkei Index to gauge economic conditions, Taiwan uses the Weighted Index to track trends. The US takes it a step further by establishing four of the most representative major indices, allowing for a more comprehensive view.

Hong Kong Stock Market Current Situation and Development Context
The Hong Kong stock market has a trading history of over 150 years and is considered one of the most mature capital markets in Asia. The first stock exchange in Hong Kong was established in 1891. After multiple mergers and reorganizations, it ultimately merged into the "Hong Kong Exchanges and Clearing Limited" in 1986. In 2000, HKEX completed restructuring and was listed, becoming Hong Kong's only official securities trading platform.
According to the latest statistics, as of the end of May 2025, the total market capitalization of Hong Kong stocks reached approximately $5.2 trillion, ranking among the top in the global securities markets. This enormous market size reflects Hong Kong's important position as an international financial hub.

Supply Gap Influences Future Market Trends
The global precious metals market is experiencing a structural shift. Analysts point out that the core drivers behind the continuous rise in platinum prices stem from long-term supply imbalances and capital reallocation. Edward Sterck, Research Director at the World Platinum Investment Council, admits that by 2025, the global platinum market will enter its third consecutive year of supply deficits, a gap expected to persist until 2029.
South Africa, which accounts for over 70% of global platinum production, has recently fallen into a "triple dilemma"—increasingly severe ore aging, frequent power outages, and extreme weather attacks. These structural issues have led to a continuous decline in output, with the spot market indicator—the platinum monthly leasing rate—rising to a historic high of 14.12%, fully reflecting market tension.
Federal Reserve Rate Cuts Drive Precious Metals Rally
On December 18, platinum prices surged over 3%, closing at 197

Currently, Bitcoin is hovering around $91.17K, and market sentiment is extremely fearful. The Federal Reserve's recent interest rate cut policy has sparked disagreements, and future liquidity improvements may be slow. On-chain market signals indicate that investors are withdrawing funds from exchanges, suggesting bottom accumulation. Different investors should adopt differentiated strategies based on market conditions; long-term holders can focus on buying opportunities at historical lows. The upcoming leadership change at the Federal Reserve may impact liquidity, but the overall market trend remains positive. Investors need to seize long-term opportunities.

At the end of the year, the crypto market faces a "liquidity vacuum" dilemma. Ethereum(ETH) has recently lacked trading volume support, quickly retreating after a surge. Institutional fund outflows have increased, while retail investors are significantly adding to their positions. The key support level is at 2970-3000. If it falls below 2900, the risk will increase. It is recommended to maintain a light position and set stop-losses, and look for opportunities once liquidity recovers.

The Core Drivers of Strong Stock Price Performance
On the 23rd, Taiwan's leading advanced materials and precious metals recycling company, Koyo Industrial (1785), saw its stock price break through a nearly six-month consolidation range, with a strong intraday limit-up. It ultimately closed at 69.3 NT dollars, reaching a new high not seen since July last year, surpassing one and a half years. This rally is not a fleeting phenomenon; at the close, there were still tens of thousands of buy orders queued at the limit-up, reflecting the market's shift from cautious observation to optimistic outlook on Koyo Industrial.
Dual Engines of Fundamental Growth, Revenue and Profit Rise Together
Koyo Industrial's latest consolidated revenue for November reached 3.816 billion NT dollars, a month-on-month increase of 14% and a year-on-year growth of 26.39%. Not only did this set a new record for the month, but the cumulative revenue for the first 11 months also refreshed the same period records of the past decade. Behind this impressive performance is the company's continuous optimization of its VAS (Value-Added Services, which excludes the raw material costs of precious metals) business. Compared to general precious metals trading, the gross margin of the VAS business...

What is inflation?
Inflation, abbreviated as "inflation," refers to an economic phenomenon where prices continuously rise over a period of time. When inflation occurs, the purchasing power of the same amount of money gradually decreases, in simple terms, money becomes increasingly worthless. The most common indicator used to measure inflation is the Consumer Price Index (CPI), which reflects changes in the prices of goods and services purchased by consumers.
Where does inflation come from?
The essence of inflation is that the amount of money circulating within the economy exceeds the actual demand, with too much money chasing limited goods. The main factors causing inflation include:
Demand-pull inflation: When demand for goods increases, businesses boost production and raise prices. As business profits increase, it further stimulates consumption, creating a cycle. Although this leads to rising prices, it also drives economic growth (GDP). Governments often actively stimulate demand to promote economic development.
Cost-push inflation: Raw materials

The divergence rate is a technical indicator that measures the deviation of stock prices from moving averages and can reflect market sentiment. Its calculation requires selecting appropriate moving average periods and parameters, and adjusting them flexibly. To effectively use the divergence rate to find buy and sell points, it is necessary to set overbought and oversold thresholds, combine multiple moving averages and other technical indicators for analysis, and avoid using it alone, in order to improve trading success rates.

Leverage is the mechanism of borrowing in trading, and the leverage ratio is a measure of its strength.

The Four Main Players in the US Stock Futures Market
When it comes to US stock futures trading, we must mention the four most active futures contracts on the American exchanges. These contracts track the S&P 500 Index, Nasdaq 100, Russell 2000, and Dow Jones Industrial Average, collectively forming the core trading ecosystem of the US stock futures market.

Omnibus account fees are high, suitable for small and infrequent trades; while overseas brokers offer low commissions, suitable for those with sufficient funds and frequent trading. When choosing, consider trading amount and frequency to find the most cost-effective path.

The current global geopolitical situation is tense, regional conflicts are frequent, and countries' defense spending continues to rise. The underlying logic is simple—modern warfare emphasizes technology, information, and precision strikes rather than manpower tactics. The rise of new weapons such as drones, precision missiles, and information warfare has created long-term growth opportunities for a number of defense stocks. For investors, the key challenge is how to accurately select among numerous military industrial companies.
What are military stocks and arms stocks?
Military stocks (or arms stocks) generally refer to publicly listed companies whose products or services are related to national defense, covering a wide range. From small items like military water bottles and uniforms to large systems like fighter jets and missile systems, as long as the company supplies directly or indirectly to defense departments, it can be classified as a military stock.
In a broad sense, as long as the company's clients include government defense departments, or its upstream suppliers have business dealings with the Ministry of Defense, the company has military industry attributes. This also explains why some stocks that seem "unrelated"

By December 2025, the Taiwanese dollar against the Japanese yen reached a level of 4.85, appreciating nearly 9% since the beginning of the year. Whether you're planning a shopping trip to Tokyo or positioning for hedging assets amid exchange rate fluctuations, now is the critical moment. But did you know? Simply choosing different exchange channels can result in cost differences of up to thousands of yuan.
Two main reasons to exchange for Japanese yen
Travel and Consumption
Traveling to Japan remains the favorite overseas choice for Taiwanese people. Tokyo department stores, Osaka night markets, Hokkaido hot springs—these classic attractions mostly accept cash (credit card penetration is only 60%), making yen cash a necessity. Additionally, from purchasing Japanese cosmetics and anime merchandise to online shopping in Japan, many enthusiasts are accustomed to transacting directly in yen. Those planning to study abroad or work holiday in Japan also need to exchange currency in advance to avoid the cost pressures caused by sudden exchange rate fluctuations.
Financial Investment Perspective
The Japanese yen is one of the world's three major safe-haven currencies (along with the US dollar and Swiss franc).
