For investors, macroeconomic indicators are like a "health report" for the stock market. Among all indicators, the world GDP ranking is arguably the most important. Many people ask: Why must we look at GDP? The answer is simple—it directly reflects a country's economic strength, which in turn affects your investment returns.
What exactly does the world GDP ranking tell us?
GDP (Gross Domestic Product) is a core indicator measuring the size of a country's economy. Simply put: it is the total value of all final goods and services produced by a country within a certain period.
What can you learn from the world GDP ranking? Three core pieces of information:
First, the distribution of economic influence. The higher the ranking, the greater the influence this country has in global trade, investment, and industrial competition. The United States and China are called economic giants precisely because their total GDPs are far ahead—together, their GDP accounts for about of the global total.

Rising Prices and Currency Depreciation: The Truth About Inflation
In recent years, global inflation has remained high, causing many people's savings to shrink increasingly. Simply put, inflation refers to a continuous rise in prices over a period of time, which leads to a decline in the purchasing power of your cash. The most commonly used indicator to measure inflation is the CPI (Consumer Price Index), which directly reflects the increase in your daily living costs.
This phenomenon does not occur out of nowhere; it is an inevitable result of economic operation. When the amount of money circulating in an economy exceeds the supply of goods, a situation arises where "too much money chases too few goods," driving up prices.
How does inflation occur? Four major causes you need to understand
Demand-pull inflation: The double-edged sword of economic prosperity
When consumer demand increases, the production of goods rises, corporate profits increase, and businesses further expand consumption and investment, forming a positive feedback loop. This demand

Recent fluctuations in the foreign exchange market have been frequent, with the yen's movement becoming a focal point
Entering late December, the USD/JPY exchange rate has experienced dramatic volatility. This week, Japanese Finance Minister Shōzō Katō and Deputy Finance Minister Jun Murasaki both spoke out about the currency market, emphasizing the government's concern over excessive fluctuations and hinting at possible market intervention measures in the near future. Previously, the dovish rate hike decision by the central bank had pushed the USD/JPY to a high of 157.76, and today, with the yen rebounding and breaking below 156, market expectations for government intervention have significantly increased.
In contrast, other currency pairs like the CAD/USD have shown relatively stable performance amid the dollar's movements, highlighting the unique volatility of the yen—an area of particular focus for Japanese policymakers.
Is the Christmas season really the best time for intervention?
Senior Market Analyst Matt Simpson from StoneX pointed out that if Japanese authorities decide to act, the period from Christmas to New Year, when liquidity is thin, would be the optimal window—this

West Texas Intermediate crude oil continues its upward trend due to escalating geopolitical tensions, with supply concerns deepening. The US seizure of Venezuelan oil tankers and Middle East tensions have driven prices higher, but global demand uncertainties limit further gains. On the technical side, attention should be paid to the resistance at $57.00 and the support between $55.00 and $54.90, and market signals should be carefully evaluated.

The performance of the RMB in 2025 can be described as a "bright future after darkness." After three consecutive years of depreciation against the US dollar, this year witnessed a significant shift in the exchange rate trend. Based on annual data, the USD to RMB exchange rate fluctuated bidirectionally within the 7.1 to 7.3 range, appreciating a total of 2.40%, demonstrating clear resilience. The offshore RMB experienced slightly larger fluctuations, moving between 7.1 and 7.4, with an appreciation of 2.80%.
November 26, 2025, became a key milestone—driven by easing US-China trade relations and rising expectations of Federal Reserve rate cuts, the RMB appreciated against the US dollar to below 7.08, reaching a low of 7.0765, marking the strongest performance in nearly a year.
Exchange Rate Trend Review: From Pressure to Reversal
The pressure in the first half of the year was indeed significant. With increasing global tariff policy uncertainties and the continuous strengthening of the US dollar index, the offshore RMB once fell below the 7.40 threshold, and the US dollar against the RMB...

The fluctuations of the US stock market often trigger the nerves of global investors. Every major adjustment is not a sudden attack but has its clues. When the Dow Jones Industrial Average, Nasdaq Composite, and S&P 500 experience deep corrections, what market signals are hidden behind them? How should investors respond rationally?
Historical Reflection: Two Profound Lessons from Major US Stock Market Crashes
To understand today's sharp decline in the US stock market, it is helpful to review two of the most representative historical moments.
Impact of the 2008 Financial Crisis
In 2008, the collapse of the subprime mortgage market triggered an earthquake in the global financial system. From the end of 2007 to the end of 2008, the Dow Jones Industrial Average fell by over 33%, and the Nasdaq Composite dropped more than 40%. This crisis was caused by excessive leverage and risk accumulation in financial institutions, leading to a global credit crunch and economic recession.

Only a year ago, the market experienced a rapid and significant downturn due to the COVID-19 pandemic, which...

When investing in stocks, the Price-to-Earnings ratio is a core valuation tool that must be understood. Many investors still have some confusion about the "meaning of the P/E ratio" and don't know how to use this indicator to judge a stock's true value. In fact, the P/E ratio is not mysterious; once you understand its principles and calculation method, even beginners can quickly get started.
Meaning of the P/E ratio: Understand this key indicator in one sentence
The P/E ratio (PE or PER) simply indicates: how many years it will take to recover your investment through the company's earnings.
From another perspective, the P/E ratio is a measure of whether a stock is "expensive or cheap." For example, if a stock has a P/E ratio of 15, it means that it would take 15 years for the company to earn enough to match its current market value, or in other words, you need 15 years to recoup your investment through the company's profits.
The P/E ratio is also called the Price-to-Earnings ratio and is the most common valuation method in the stock market. It can tell investors, at this moment,

The Essence of Futures—Lock in Future Prices
The term "futures" may sound mysterious, but its origins are quite simple. During the agricultural society era, farmers faced a core dilemma: price uncertainty—selling grains cheaply during bumper harvests and struggling to find high prices during poor yields. To hedge against this risk, merchants created an agreement: to decide today the trading price and quantity for a future date. This was the prototype of futures.
In modern times, futures have evolved into a type of derivative financial contract. Its key feature is: two parties sign an agreement to buy or sell a specific quantity of an underlying asset at a predetermined price on a future date. The underlying asset can be commodities (oil, gold, agricultural products) or financial assets (stock indices, exchange rates, bonds).
The Core Difference Between Futures and Spot
Before understanding futures, it is essential to distinguish it from spot trading. These two differ in terms of capital investment, delivery method, and trading

ADR Quick Start Guide
American Depositary Receipts (ADRs) are an important tool for foreign companies to enter the U.S. stock market. In simple terms, when overseas companies want to trade in the U.S., they do so by issuing ADRs—American depositary banks convert foreign stocks into ADR certificates, allowing investors to trade them just like regular U.S. stocks.
What does this mean for investors? You can buy and sell these foreign companies' stocks directly on Nasdaq, NYSE, or over-the-counter markets without having to open an account locally or exchange currency. However, you should also be aware of liquidity risks, exchange rate fluctuations, and regulatory differences among ADR levels.
How do ADRs work? A Deep Dive into the Issuance Mechanism
Foreign companies deposit their local stocks with a U.S. depositary bank, which then issues corresponding ADR certificates. This way, the stocks can circulate in the U.S. market.

Policy Signals Behind the Sudden Exchange Rate Shift
On December 23, the USD/JPY exchange rate experienced a significant rebound, breaking through the 156 level. The catalyst came from a firm stance from Japan's financial authorities—Finance Minister Shunichi Suzuki stated that he has the authority for "bold actions," followed by Deputy Finance Minister Masamura Jun, who emphasized that the government will take appropriate measures against excessive volatility. The market responded immediately; the previously rising dollar came under pressure, and the yen reversed its depreciation trend.
Looking back less than a week, after the dovish rate hike news from the Bank of Japan, the USD/JPY once surged to a high of 157.76. The intensive statements from government officials broke this upward momentum, indicating that authorities have limited tolerance for excessive yen depreciation.
Has the intervention window truly arrived?
Regarding when the government will actually step into the market, opinions are divided. StoneX analyst believes that if Japanese authorities do intervene, the period from Christmas to New Year, when liquidity is scarce, might actually allow

New Year First Week Market Rhythm: Short-term Volatility Struggles to Break 90,000 Level
Entering the first week of 2026, Bitcoin against the US dollar continues to fluctuate at high levels, currently hovering around $93,810. After multiple attempts to break the $90,000 mark last week, although ultimately unable to stabilize above it, the highest point this week reached $94,800, indicating that bulls are still vying for this psychological level.
Meanwhile, Ethereum performed relatively strongly, trading at $3,240, with a 24-hour increase of 2.18%, and daily trading range between $92,420 and $94,800. Market participants note that the low liquidity environment at the end of the year is gradually improving, but in the short term, prices remain susceptible to the impact of large options expirations.
Structural Changes During Liquidity Restoration
Following the record-breaking options settlement last Friday, significant changes have occurred in the market's institutional structure. According to QCP Capital analysis, open interest has decreased sharply by nearly 50%, indicating that many traders

In stock investing, the Price-to-Earnings ratio (PE) is perhaps the most frequently heard yet easily confused concept. Investment advisors and analysts often ask, "Is this company's PE ratio reasonable?" or "What is the current PE level?" However, not many investors truly understand how to calculate the PE ratio. This article will guide you to deeply understand the core logic of the PE ratio and learn how to use it to evaluate stock valuation.
What exactly does the PE ratio measure?
The PE ratio, also known as the Price-to-Earnings ratio, abbreviated as PE or PER (Price-to-Earning Ratio), essentially answers a question: At the current price, how long will it take for the company's profits to recover the investment cost?
Taking TSMC as an example, suppose the current PE ratio is around 13. What does this mean? It indicates that it would take 13 years for the company to earn enough to match its current market valuation, or it can be understood as investors buying at the current price need

When it comes to short selling, many retail investors are still confused. Actually, it’s simple to understand as a reverse operation — when you anticipate the market will fall, you sell an asset you don’t yet own in advance, and buy it back when the price drops, earning the difference in between. It sounds like a fairy tale, but it is indeed a legally recognized way to make money in the investment market.
If some people are going long (profiting from rising prices), there must be others going short (profiting from falling prices). This balance between long and short positions keeps the market rational, preventing it from skyrocketing wildly or crashing endlessly. Truly smart investors never bet solely on one direction but switch strategies flexibly based on market conditions.
What is short selling? The core mechanism explained in one sentence
The essence of short selling is "sell high, buy low."
You don’t own the stock or currency now, but you borrow it from a broker and sell it immediately at the current price. When the market drops, you buy it back at a lower price and return it to the broker, earning the difference.

Platinum, which has stirred waves in the precious metals market, is expected to perform brilliantly in 2025. From a steady trend at the beginning of the year to reaching a historic high of $2,381.25 by the end of the year, this surge has left many onlookers both excited and anxious—should they seize the opportunity to invest or wait for a better moment? Is this merely a short-term speculative frenzy, or a genuine trend driven by medium- to long-term demand?
Several Ways to Understand Before Investing in Platinum
Before deciding whether to get involved, investors need to understand the specific trading options available. Depending on risk tolerance and capital size, there are various flexible ways to participate in the platinum market.
Buying physical platinum directly is the most traditional approach. This means you actually own the metal itself, but it comes with additional costs such as sales tax, insurance, and storage fees. Compared to gold, platinum has higher refining difficulty and costs, so investors usually have to pay a premium for this.
