The Correlation Logic Between Copper Prices and Copper Stocks
In this recent rally, both spot copper and copper stocks have performed remarkably well. Taking Freeport-McMoRan (FCX), the world's largest copper producer, as an example, its stock has surged over 30% in just 45 days, while international copper prices have increased by 17% during the same period. This reflects a simple yet effective investment logic: the movement of copper stocks is highly synchronized with copper price fluctuations.
Why is this the case? The reason is straightforward—core revenue for copper mining companies comes from the extraction and sale of copper. When copper prices rise, it directly boosts the company's gross profit margin, causing the stock price to rise accordingly. If you compare the trend chart of copper mining ETFs (COPX) with LME copper prices, you'll find that the two lines are basically overlapping, which is the best proof.
Breaking Down the Copper Industry Chain: Investment Opportunities Vary Significantly at Different Stages

Mastering the currency symbols of various countries is crucial for foreign exchange traders, as it can improve decision-making speed and seize market opportunities. The article provides a currency symbol reference table, shortcut keys, and special notes on symbol confusion, as well as an introduction to the concept and application of forex currency pairs, to help traders develop effective trading strategies.

When it comes to "Ponzi schemes," many people are itching with hatred—because they exploit human weaknesses, weave dreams of wealth, and sweep away victims' hard-earned money. Interestingly, most scams in the financial fraud field can be traced back to some variant of this pattern. Although we've all heard of the name, few truly understand its origins, operational logic, and prevention methods. Today, we will delve into the evolution of this century-old scam, analyze some iconic cases, and explore how to make your money safer.
From an Italian immigrant to the dark legend of the "Father of Finance"
The name "Ponzi scheme" originates from Charles Ponzi, an Italian-born individual. The operational logic of this type of scam seems simple: promise investors low-risk, high-return investment opportunities to attract their funds. But the "investment returns" here are not derived from real business or assets.

Want to improve your success rate in stock or crypto asset trading? Learning how to use the KDJ indicator is a must for many retail investors. This technical tool, known as one of the "Three Treasures of Retail Investors," how does it help traders identify turning points amid market volatility? This article will systematically explain the core principles of the KDJ indicator, practical applications, and common pitfalls.
The essence of the KDJ indicator: The secret of three lines
The stochastic indicator KDJ consists of three curves: K line (fast line), D line (slow line), and J line (direction line). They compare the relationship between the highest price, lowest price, and closing price over a period to determine whether the market is overbought or oversold.
Simply put:
- K and D values: reflect overbought/oversold levels (above 80 is overbought, below 20 is oversold)
- J value: measures the divergence between K and D, with higher sensitivity
The crossovers and divergences of these three lines are the most critical buy and sell signals in KDJ indicator usage.

Cryptocurrencies have evolved from niche investment assets to an important option for asset allocation, especially against the backdrop of increasing global economic uncertainty. However, with thousands of virtual currencies available, investors often face a dilemma in choosing. This article will start from the actual market situation to help you understand how to select, how to invest, and which virtual currencies are currently the most worth paying attention to.
Market Logic You Must Know Before Investing in Virtual Currencies
Regarding virtual currency investment, there is a classic saying circulating in the industry: "Buy altcoins in a bull market, buy mainstream coins in a bear market." The investment wisdom behind this phrase is worth a deep understanding.
Why are altcoins suitable in a bull market? Because altcoins often see more astonishing gains. When market sentiment is high, funds flow into these high-risk assets seeking maximum returns. But the price volatility is intense, and even a slight disturbance can lead to a crash.
Why do investors return to mainstream coins in a bear market? When the market enters a downward cycle, investors start seeking stability. Mainstream coins, due to their large market capitalization,

In recent years, the global gold market has continued to heat up. According to data from the World Gold Council, central banks have increased their gold holdings for three consecutive years, reaching a new high in half a century. For Taiwanese investors, spot gold is gradually becoming one of the options for asset allocation. However, many people are still unfamiliar with "spot gold." What exactly is it? How can one participate? This article will provide a detailed analysis.
What is Spot Gold? How Does It Differ from Physical Gold?
Spot gold (also known as "international gold" or "London gold") is a virtual trading product based on XAUUSD, tracking the current international gold price in real time. Unlike purchasing physical gold bars or coins, spot gold is a paper-based transaction. Investors only need to buy and sell through electronic platforms without involving physical delivery.
The main differences are as follows:
Physical Gold: Buying gold bars or coins for long-term preservation, with higher costs (including storage and appraisal fees). It offers strong hedging effects but is less liquid than spot products.

The Binance Coin (BNB) is experiencing steady growth, leading the platform token sector despite a slight recent decline. It remains a key player, reflecting market confidence in its ecosystem. BNB is the primary option for those seeking exposure in this space.

A delivery driver in Zhejiang entered the crypto market with just 500 USDT (approximately 3,000 yuan) and watched his investment fall and rise dramatically, eventually reaching 60,000 USDT (around 400,000 yuan) within half a year. This 120-fold return—equivalent to 10 years of delivery

In March 2021, a Wall Street investment manager lost $20 billion in just 48 hours, becoming the fastest person in history to lose money. Behind this shocking event in the financial world reflects a seemingly simple yet extremely dangerous trading concept—liquidation and margin calls.
Understanding from the big players' liquidations: Why did Bill Hwang lose so much?
Bill Hwang's investment strategy is straightforward: select promising company stocks and use大量杠杆 to amplify returns. With this approach, he turned $220 million into $20 billion over 10 years.
But high leverage is like a double-edged sword. When the stock market experienced huge fluctuations in 2021, his holdings began to come under pressure. Brokers, in order to protect their own funds, enforced forced liquidation on him.
The problem was—his shareholding was too large. When the broker sold such a large amount of stock all at once to

On December 16th, the U.S. Bureau of Labor Statistics will release key employment data, including October non-farm payrolls and the full November data, which the market is eagerly awaiting. According to current expectations, October non-farm employment is projected to decline by 10,000, but November data is expected to rebound strongly, adding approximately 130,000 jobs. This set of data will directly influence the subsequent performance of the US dollar, US stocks, and gold.
However, Citigroup economists have poured cold water on these expectations. They point out that the November rebound may mainly be due to seasonal adjustment factors rather than a substantial improvement in labor demand. Coupled with the complications in data collection caused by the government shutdown, the reference value of this week's report is somewhat diminished. Kevin Flanagan, Head of Fixed Income Strategy at WisdomTree, also believes that the truly significant NFP data will be released on January 9, 2026, when the full December employment report will surface.

Why Silver Is Becoming the New Favorite for Smart Investors
Many people are used to only watching gold, but they overlook the unique opportunities of silver. It's not that silver is less valuable because it's cheaper than gold; rather, due to its relatively low price and broader applications, silver shows a completely different growth potential in 2025.
Silver vs Gold: Three Core Differences
Industrial Use Determines the Future
Gold is mainly a safe-haven asset, but silver is different. Solar panels, electric vehicles, semiconductors, 5G, AI data centers—these industries all rely on silver. As the green energy transition accelerates in 2025 and AI computing demand explodes, silver's annual usage growth exceeds 20%. In other words, silver has shifted from a pure precious metal to a key industrial commodity, and demand-wise, it has the edge.
Low Price Base, Greater Upside
The current price of gold is about 60-120 times that of silver. With the same amount of capital, you can buy more silver. Imagine a sum of money used to buy gold, which can only purchase 1 unit, whereas with silver, you can acquire units.

Reduction as an important financial decision for publicly listed companies has a profound impact on shareholder equity and market performance. Many investors find this complex financial operation confusing, unsure of what reduction actually means, and even less clear about how it will change stock value. This guide will systematically break down the core concepts of reduction, implementation methods, stock price linkage mechanisms, and the strategies investors should adopt.
Understanding Reduction: Why Do Companies Make This Decision?
Core Definition of Reduction
Reduction refers to the proactive financial action taken by a listed company to decrease its total issued share capital. Specific methods include share buybacks from the secondary market, cancellation of unlisted shares, or directly reducing the scale of share capital. What appears to be a simple numerical adjustment conceals strategic considerations regarding the company's capital structure.
Multiple Motivations for Companies to Implement Reduction
Corporate decision-makers typically choose reduction based on the following considerations:
- Reshaping Financial Structure: By reducing the total share capital, the company can

The latest survey reveals a cloud of gloom over the US energy industry. The third-quarter regional survey warning issued recently by the Dallas Federal Reserve Bank sends a clear signal—major US energy hubs from northern Texas and Louisiana to southern New Mexico are experiencing widespread pessimism among oil and natural gas industry executives.
Shale Oil Dilemma Emerges, Cost Pressures Mount
This survey, which includes 139 corporate decision-makers, provides an in-depth scan of regions that play a crucial role in the global energy supply landscape. The interviewed executives openly acknowledge the current difficulties: the US shale oil industry is on the brink of collapse, and the once-globally renowned energy sector is now severely impacted by worsening policy environments and economic outlook disruptions.
An industry insider bluntly pointed out that the golden age of shale oil is over. Although US oil reserves remain abundant, the key issue lies in economic viability—if the price per barrel cannot stay above $60, the entire industry faces a survival crisis. This

In the global financial markets, the daily trading volume of foreign exchange reaches trillions of dollars, far surpassing other investment assets such as stocks, bonds, and gold. In recent years, currency fluctuations have been frequent, and exchange rates in mature markets have also experienced dramatic changes, bringing unprecedented opportunities for ordinary investors. At the same time, the practicality of foreign currencies has broadened their audience—whether for traveling abroad, overseas shopping, or international trade—necessitating currency exchange operations, thus lowering the barrier to participating in the foreign exchange market.
If you are interested in buying and selling foreign currencies but lack practical experience, this article will systematically analyze the principles of arbitrage trading, various methods, practical skills, and the timing strategies of different trading approaches to help you find the investment path that best suits you.
Core Logic of Foreign Currency Trading: What is the Exchange Spread?
The essential goal of buying and selling foreign currencies is only one: to profit from the exchange spread.
The exchange spread refers to the difference in the exchange rate of the same currency at different times or through different trading channels.

Taiwan stocks are stuck at 28,000 points at a high level, but have you noticed? The flood of funds is pouring into financial stocks. Compared to Tech Stocks, which are cut by 10% every time they pull back, the volatility of financial stocks is simply child's play, and they can still steadily yield 5-7%. This is not a coincidence; capital is undergoing a major shift of "value reversion."
Why are financial stocks especially attractive now?
Unbelievably cheap valuation
Tech Stocks are already trading at over 30 times P/E, but their growth momentum is slowing down. In contrast, most bank stocks are at 10-12 times, a gap that’s hard to compare. As the economy's soft landing becomes more apparent, smart capital naturally starts to pick up bargains.
Interest rate environment is not the enemy
Don’t be fooled by the saying "rate cuts hurt banks." Taiwan’s financial industry has already earned over 560 billion NT dollars in the first 11 months, setting a new record. As long as the economy doesn’t hard land, their dividend-paying capacity will only strengthen by 2026. That’s why now is the time to seize the opportunity with room for a rebound.
A defensive fortress in the economic cycle

The Japanese Yen has become a standard asset for Asian investors, especially during times of continuous TWD depreciation and rising global economic uncertainties. In December 2025, the TWD/JPY exchange rate reached 4.85, appreciating by 8.7% compared to the beginning of the year, creating significant opportunities for currency exchange gains. Many people ask: Is it worthwhile to exchange for JPY now? The answer is yes, but the key lies in choosing the right exchange channel. A single decision could save you an extra 2,000 NT dollars.
Why has the Japanese Yen become a new favorite? Three perspectives to interpret
Necessity for Travel and Daily Expenses
Shopping in Tokyo, skiing in Hokkaido, vacationing in Okinawa—travel to Japan has become a collective habit among Taiwanese. Unlike Europe and America, cash still accounts for 60% of retail transactions in Japan, and credit card penetration is relatively low. Purchasing agents and Japanese online shoppers also need to pay directly in JPY, making currency exchange a necessity. For young people planning to study or work in Japan, exchanging currency in advance can help avoid last-minute exchange issues.

Many novice investors are thinking about how to quickly enter the US stock market, and a foreign securities trading account has become the most common method for Taiwanese people. However, before opening an account, you must understand: how exactly does a foreign securities trading account work, what are the costs, and what trading restrictions exist—all of which directly affect your investment returns.
The essence of a foreign securities trading account: the client's order, then entrusted
The full name of a foreign securities trading account is "Trustee Buying and Selling of Foreign Securities Business." It sounds complicated, but the core concept is actually very simple.
You want to buy US stocks but don't want to open an overseas account yourself or deal with remittances and foreign currency issues. So, you open a foreign securities trading account with a Taiwanese broker, and the broker then forwards your order to an overseas partner broker for execution—your order goes through a single "hand-off," which is why it's called a "foreign securities trading account."
Through this method, you can invest in stocks, ETFs, and bonds across multiple markets such as the US, Japan, Hong Kong, and China. In Taiwan, using a foreign securities trading account to buy US stock ETFs is the most traded volume.

Do you have this kind of trouble: even though you're exchanging only Japanese Yen, why do some people end up paying an extra NT$2,000 in fees before realizing it? In December 2025, the NT dollar to Japanese Yen exchange rate hit 4.85, with both travel and investment enthusiasm rising. But if you choose the wrong currency exchange method, a few thousand dollars can disappear just like that.
Instead of regretting it later, it's better to understand the costs, advantages, and disadvantages of the four major currency exchange channels now.
Why is it worth paying attention to exchanging Japanese Yen now?
The Yen is not just a travel currency; there are two underlying reasons behind it that you should pay attention to.
Short-term positive: Exchange rate appreciation
At the beginning of the year, the NT dollar to Japanese Yen was about 4.46, and today it has risen to 4.85, an accumulated appreciation of 8.7%. For currency exchangers, this means you can get more Yen for the same amount of NT dollars. But don’t think this trend will last forever—Bank of Japan Governor Ueda Kazuo recently made hawkish comments, expecting a rate hike to 0.75% on December 19 (a 30-year high), with market expectations of an 80% chance of a rate increase.
