The Taiwan stock market index is the Weighted Stock Price Index, reflecting the overall market performance. It uses a market capitalization weighting method, giving larger companies a greater influence on the index, which may conceal the performance of small and medium-sized enterprises.

When investing through tools like ETFs, attention should be paid to risk assessment and market trends.

Every year, there are four days when the U.S. stock market stages a grand show of the "invisible force." These four days are known as Quadruple Witching Days, which refer to the days when four major U.S. derivative financial products—single stock futures, single stock options, stock index futures, and stock index options—expire simultaneously. They fall on the third Friday of March, June, September, and December each year.
Why do Quadruple Witching Days become must-watch dates for traders?
The origin of this name may seem mysterious, but it actually stems from a simple market phenomenon: during derivatives expiration, futures prices are forced to align with spot prices, as if some "witchcraft" pulls the two to the same level. More importantly, on this day, fundamentals take a backseat, and chips and the intentions of market makers become the dominant forces driving prices.
Specifically, there is usually a price difference between futures and the spot market. As the expiration date approaches, this spread gradually narrows. Buyers anticipate

Speaking of currency exchange, Taiwanese people are most familiar with Japanese Yen. But did you know? Just choosing the right currency exchange channel can save you a lot of handling fees, and even save you several thousand dollars. Today, we will break down the four current methods of exchanging Japanese Yen, so you can understand exactly where the costs differ.
Is it really cost-effective to exchange Yen now?
As of December 10, 2025, the TWD/JPY exchange rate has risen above 4.85, up from 4.46 at the beginning of the year, an appreciation of about 8.7%. This number may not seem like much, but the actual amount saved is significant—exchanging 50,000 TWD now yields nearly 4,400 more Yen than at the start of the year, which is equivalent to an exchange gain of over NT$800.
But don't rush to exchange all at once. Currently, the Yen is in a fluctuation zone, with the Bank of Japan adopting a hawkish stance (expected to raise interest rates to 0.75% in December, a 30-year high), while the US is entering a rate-cut cycle. These factors will influence short-term exchange rates. USD/JPY from this year

In the investment circle, you've probably heard the phrase "U.S. stock market closes, but the night session is the real stage." But what exactly is an electronic trading session? What are the differences between futures trading and stock trading? Can 24-hour nonstop trading really make money? This article will give you an in-depth understanding of the operation logic of the U.S. stock futures market.
Breaking the Time Limit: The Core Concept of Electronic Trading
Electronic trading, commonly known as the night session or after-hours trading, is an innovative mechanism that breaks the constraints of traditional trading hours. It allows global investors to continue participating in the market outside normal trading hours, reflecting the impact of overnight news on stock prices.
The regular trading window for U.S. stocks is from 9:30 AM to 4:00 PM Eastern Time. Outside this period, after-hours trading provides holders and opportunists with the chance to adjust their positions. This segment attracts major funds, news insiders, and professional traders, who position themselves in advance based on the latest information to prepare for the next day's market movements.
In comparison, the U.S. futures market is even more

Yesterday, the Taipei stock market experienced a shocking decline, influenced by the previous sharp drop in US tech stocks. The weighted index opened with a gap down, falling as deep as 27,684 points, with a single-day fluctuation of over 500 points, officially breaking the psychological barrier of 28,000 points. The stock king, Xinhwa, became a battleground between bulls and bears around 6,600 yuan, while TSMC plummeted by 30 yuan at the open to around 1,450 yuan. Behind this chain reaction not only reflects a short-term technical collapse but also exposes the pricing distortions caused by over a year of AI frenzy.
Why is the chain reaction of the US stock market crash so intense?
Last Friday, the four major US stock indices all closed lower, becoming the direct trigger for the decline in the Taiwan stock market yesterday. Among them, Broadcom dropped 11.43% in a single day, and Nvidia also fell more than 3%. The simultaneous decline of these chip giants sent a warning signal to the market. Leading stocks in the Taiwan stock market, including TSMC, MediaTek, and Hon Hai, all responded by falling across the board, highlighting the electronic sector as a heavy casualty area.

The foreign exchange market is the largest financial market in the world by trading volume, with an average daily turnover of over $6 trillion. However, for investors new to this field, to consistently make profits from buying and selling foreign currencies, it is essential to first understand the market operation logic and their own trading capabilities.
What is the best time to buy and sell foreign currencies?
Many people think that they can trade foreign currencies at any time. In fact, different trading channels have completely different time restrictions.
Bank foreign exchange trading windows are limited by business hours, usually only available from 9:00 AM to 3:30 PM, and cannot be operated on weekends and public holidays. This is very inconvenient for investors who need to flexibly adjust their positions.
Forex margin trading, on the other hand, enjoys a 24-hour advantage. Since there is no unified exchange, the market consists of four major sessions—London, Sydney, Tokyo, and New York. These sessions overlap with each other, allowing traders to buy and sell foreign currencies continuously from Monday to Friday, 24/7. If

Taiwan Dollar to Japanese Yen reaches 4.85! Since the beginning of the year, it has appreciated by 8.7%, boosting travel demand to Japan and yen asset allocation. But is exchanging yen really only possible at banks? Just choosing the wrong channel could cost you an extra 2,000 TWD.

Online settlement + airport withdrawal: Loss of 300-800 TWD (reservation system, preferential rates)
Bank foreign currency ATM: Loss of 500-1,000 TWD (24-hour flexibility, based on)

For Taiwanese investors, the cost structure of entering the US stock market is often a key factor in decision-making. Is it better to go through domestic brokerage firms' sub-brokerage channels or to open an overseas brokerage account directly? How big is the difference? This article will analyze the true burden of US stock sub-brokerage fees from a cost perspective.
Choosing a trading method determines how much you pay
There are basically two ways to trade US stocks in Taiwan, and the hidden fee differences are significant.
What is sub-brokerage?
Sub-brokerage (Sub-Brokerage) allows you to buy and sell US stocks or ETFs directly through a domestic broker without opening an overseas account. Investors place orders with domestic brokers, who then delegate the order to US brokers, hence the term "sub-brokerage."
The advantage of this method is that all transactions are conducted in New Taiwan Dollars, with domestic brokers automatically handling currency exchange and the complex processes of international settlement. However, because of the complex procedures involved, US stock sub-brokerage fees are generally higher,

Many Taiwanese want to trade US stocks but are stuck with two questions: "Should I choose a discretionary order or open an account with an overseas broker?" "Which method is the most cost-effective?" Today, we will address these questions all at once and show you how to choose the most economical option with actual numbers.
Which path to take? The fundamental differences between discretionary orders and overseas brokers
Discretionary order is officially called "Trustee Buying and Selling of Foreign Securities Business." Simply put, you open an account with a domestic broker (like Fubon, Cathay, E.SUN, etc.), and the domestic broker acts on your behalf to place orders in the US stock market. Because the order passes through two steps—"domestic broker → US stock market"—it is called a "discretionary order."
The advantages of this method are obvious: you deposit NT dollars directly, no need to exchange currency yourself, and your account is protected by Taiwan's Financial Supervisory Commission. The downside is higher transaction fees, usually between 0.15% and 1% of the trading amount, with significant differences among brokers.
Overseas brokers are straightforward—you directly open an account with a US stockbroker.

Why Are Traders All Using Moving Averages?
Among the many tools in technical analysis, the Moving Average (MA) is an essential indicator that every trader should learn. Especially the Simple Moving Average (SMA), because it is intuitive and easy to understand, making it particularly suitable for beginners to quickly get started. But what exactly is an SMA, and how can it help improve trading decisions?
Core Principles of the Simple Moving Average
The Simple Moving Average is a technical analysis indicator that helps traders quickly identify the direction of an asset's price movement. Its calculation logic is straightforward: take the closing prices of an asset over a specific period, sum them all up, and divide by the number of days to get a data point.
For example, suppose a stock's closing prices over the past 15 days are as follows:
First week (5 days): 30, 35, 38, 29, 31
