Why learn technical indicators?
When investing in stocks, fundamental and technical analysis are two major tools. Fundamental analysis looks at a company's operating data, while technical analysis relies on price trends and technical indicators. Stock technical indicators are like a toolbox, transforming historical price data into visual charts using formulas, helping you quickly judge market trends and buy/sell timing.
Compared to candlestick analysis, technical indicators have the advantages of low entry barriers and being intuitive and easy to understand, making them especially suitable for beginner investors. However, it's important to note that indicators are based on past data and have a lagging effect. It's best not to rely solely on a single indicator but to combine multiple tools and fundamental analysis for comprehensive judgment.
How are stock technical analysis indicators classified?
Common stock technical analysis indicators are divided into three main categories:
Trend indicators: Determine the future direction of the market, predict bullish or bearish trends
- Bollinger Bands: Composed of three green lines that move with the candlesticks, used to observe volatility ranges

In the second half of 2024, the global financial markets will迎来 an important turning point— the Federal Reserve officially initiates a rate cut cycle. Accompanying this policy shift, many investors have noticed signs of the US dollar beginning to weaken continuously. Why is the US dollar falling? Will it continue to decline in the future? This involves deep changes in the global economic landscape and is worth in-depth analysis.
The fundamental reason for the US dollar's continuous decline
The rate cut cycle changes capital flows
When the Federal Reserve announces a rate cut, the most immediate market reaction is—the attractiveness of the US dollar decreases. Imagine if the interest earned from holding dollar assets becomes less, investors will naturally start looking for other assets with better returns. Cryptocurrencies, gold, growth stocks, and other risk assets are thus in demand, with a large amount of capital flowing out of dollar assets.
According to the latest Fed dot plot expectations, the US dollar interest rate will fall to around 3% before 2026. This expectation itself is driving the market to adjust

In the toolbox of technical analysis, the KDJ indicator stands out with its simplicity and efficiency, becoming an essential tool for many traders. Known as one of the "Three Treasures of Retail Investors," what is the magic behind the KDJ indicator that helps investors find the best entry points in volatile markets? This article will delve into the core logic, calculation methods, and practical application techniques of the KDJ indicator.
Understanding the KDJ Indicator: The Story of Three Lines
The KDJ indicator is a stochastic indicator, specifically used to identify overbought and oversold conditions and trend reversal points. It consists of three lines, each playing a different role:
- K value (Fast Line): Reflects the current price relative to recent price ranges, most sensitive to price changes
- D value (Slow Line): A smoothed version of the K value, used to filter noise and improve signal reliability
- J value (Direction-sensitive Line): Measures the divergence between the K and D lines, key to finding reversal opportunities

The Taiwanese dollar continues to face depreciation pressure, and the Japanese yen has already started its appreciation train. As of December 2025, the TWD/JPY exchange rate has reached 4.85, an 8.7% increase since the beginning of the year. This is not just a matter for travelers—investors are also beginning to pay attention to JPY allocations.

First, ask yourself: Why do I want to exchange for Japanese yen?
Travel and Consumption Scenarios
Shopping in Tokyo, skiing in Hokkaido, vacation in Okinawa—most Japanese merchants still rely on cash (credit card penetration is only 60%). Exchanging money at the airport last minute often results in the biggest losses. Additionally, purchasing agents and frequent online shoppers in Japan need to prepare JPY in advance to avoid sudden exchange rate fluctuations.
Financial Allocation Perspective
This is the key—JPY is one of the world's three major safe-haven currencies (alongside USD and Swiss Franc). When global markets are turbulent, funds flow into JPY for safety. In 2022, the Russia-Ukraine conflict...

By mid-December 2025, the exchange rate of the New Taiwan Dollar (NTD) to the Japanese Yen (JPY) reached 4.85, appreciating over 8% from 4.46 at the beginning of the year. As the Bank of Japan prepares to raise interest rates to a 30-year high, global arbitrage traders and Taiwanese investors are closely watching the Yen's movement. However, few realize that exchanging the same 50,000 NTD into Yen through the wrong channels could cost an extra 2,000 NTD.
Why is the Yen worth paying attention to? From travel to asset allocation
When it comes to foreign currency exchange, the Yen is often the first choice for Taiwanese people. The reasons are not only due to the popularity of travel to Japan but also because of the Yen's special status in the global financial markets.
In terms of travel and consumption, cash is still widely used in Japan (with only 60% credit card penetration). Whether shopping in Tokyo, skiing in Hokkaido, or vacationing in Okinawa, cash remains the primary payment method. At the same time, the culture of purchasing through agents and the needs of students working abroad for part-time jobs require regular Yen exchanges for daily expenses.
From a financial market perspective, the Yen's role is even more intriguing. The Yen and the US

The NT$ to JPY exchange rate has surged to 4.85. What opportunities are hidden behind this number? Starting from 4.46 at the beginning of the year, the Japanese Yen has appreciated by approximately 8.7% in just one year. This is not only a concern for travel consumers regarding exchange costs but also a risk hedging opportunity that asset allocators must pay attention to. Compared to other currency pairs like GBP to TWD, the Yen's position as one of the world's three major safe-haven currencies is even more prominent.
The Yen becomes the new favorite for Taiwanese investors: not just for travel purposes
In the past, people mainly exchanged Yen for shopping abroad, purchasing goods on behalf of others, or short-term study abroad. But now, the situation has changed.
In daily consumption, Japan remains the top destination for Taiwanese travelers—cash still dominates when shopping in Tokyo and Osaka (credit card penetration is only 60%), and trips to Hokkaido for skiing or Okinawa for vacations require preparing cash in Yen. Online shopping and purchasing agents also maintain a long-term demand for Yen, as Japanese drugstores, anime merchandise, clothing, and other products are often purchased in cash.

The Taiwanese dollar appreciates to a 40-year high, market sentiment fluctuates wildly
Recently, the trend of the New Taiwan dollar against the US dollar has attracted significant market attention. According to data from the USD exchange rate trend chart, within just two trading days in early May, the New Taiwan dollar appreciated nearly 10%. The single-day increase even set a 40-year record for the largest gain. On May 2, the New Taiwan dollar against the US dollar appreciated by 5%, closing at 31.064 yuan. Subsequently, on May 5, it further broke the important psychological barrier of 30 yuan, with an intraday high of 29.59 yuan, hitting a 15-month high. This wave of intense exchange rate fluctuations not only triggered the third-largest trading volume in the history of the foreign exchange market but also raised doubts about the subsequent trend.
Compared to other Asian currencies, the appreciation of the Taiwan dollar is indeed particularly remarkable. During the same period, the Singapore dollar appreciated by 1.41%, the Japanese yen by 1.5%, and the Korean won by 3.8%. However, the rapid appreciation of the Taiwan dollar stands out among Asian currencies. It is worth noting that from the beginning of the year to

The Core Value of Currency Symbols
Currency symbols serve as a visual language of recognition, playing a crucial role in international transactions. Through simple graphic symbols, traders can instantly identify the currency type, track exchange rate fluctuations, and make more accurate investment decisions. Compared to lengthy textual descriptions, writing "$100" is more efficient and intuitive than "100 US Dollars." Especially in forex trading, when dealing with common currency pairs like EUR/USD, EUR/JPY, etc., the ability to recognize symbols determines the speed of transactions.

Understanding U.S. Treasury Bonds: The Safest Investment Choice Globally
What are U.S. Treasury Bonds (Government Bonds) essentially? In simple terms, they are debt instruments issued by the U.S. government to raise funds from the market. The government commits to returning the principal and paying interest within a specified period.
Why are U.S. Treasury Bonds favored by investors worldwide? The core reason is that the U.S. government has the highest credit rating globally, and the risk of default is nearly zero. For this reason, U.S. Treasury Bonds have become the preferred safe-haven asset in international asset allocation and are the cornerstone of many investment portfolios.
Whether for individual investors, institutional entities, or central banks of various countries, U.S. Treasury Bonds are regarded as an important source of stable income. Their high liquidity and market trading volume ensure investors can enter and exit the market at any time.
The Four Main Types of U.S. Treasury Bonds
Based on maturity and interest payment methods, U.S. Treasury Bonds are mainly divided into four categories:
Short-term Treasury Bills (T-Bills)
Features: Maturity within one year, with the term in

The TWD to JPY exchange rate has reached 4.85, and the popularity of travel to Japan and demand for JPY investments are both warming up. But how to choose the most cost-effective and efficient exchange method? This article provides a comprehensive analysis of the actual costs, operational procedures, and optimal timing for four major exchange channels.
Why is it necessary to re-examine the JPY now?
Many people see the JPY as a tool for travel expenses, but few realize it has evolved into an asset option with both liquidity and hedging properties.
In terms of daily consumption, Japan travel, shopping, studying abroad, and other scenarios still require a large amount of cash in JPY. The penetration rate of Japanese credit cards is only 60%, and cash transactions remain the mainstream, especially in local towns and small businesses.
In the financial investment realm, the JPY has long been one of the world's three major safe-haven currencies (alongside USD and Swiss Franc). During the Russia-Ukraine conflict in 2022, the JPY appreciated by 8% in a single week, effectively hedging against a 10% decline in global stock markets. For Taiwanese investors, allocating JPY is equivalent to increasing exposure during the heightened volatility of the Taiwan stock market.

U.S. stocks opened higher but closed lower, with tech stocks leading the decline
On Thursday, the U.S. stock market experienced a typical "roller coaster" session. It initially rose due to Nvidia's strong Q3 earnings and September non-farm payrolls exceeding expectations, with the Nasdaq soaring over 2.5%. However, as investor caution regarding valuation risks increased, the U.S. markets ultimately pulled back across the board. The Dow Jones Industrial Average fell 0.84%; the S&P 500 declined 1.56%; the Nasdaq dropped 2.15% to 22,078 points. Chinese concept stocks performed even weaker, with the Golden Dragon Index down 3.26%. European markets performed relatively steadily, with Germany's DAX 30 up 0.5%, France's CAC 40 rising 0.34%, and the UK FTSE 100 edging up 0.21%.
Non-farm Payroll Data Analysis: Employment Growth Surpasses Expectations

For busy professionals or those who have little interest in financial analysis but need to manage their finances, investing in funds is a relatively easy path. This article will guide you to a deeper understanding of what investment funds are, how their profit mechanisms work, and how to scientifically allocate your personal asset portfolio.
First, understanding funds: a smart way to manage finances
What is an investment fund? Simply put, a fund refers to a securities investment fund, issued by banks or brokerages, which pools investors' capital and entrusts professional fund managers to handle investments, with fund custodians overseeing the funds. This is an indirect securities investment method, where investors participate in market investments by purchasing fund shares, achieving a collective investment model of profit sharing and risk sharing.
Depending on the investment target, funds can be divided into five main types: money market funds, bond funds, index funds, hybrid funds, and stock funds.
How funds generate returns: four key steps

In December 2025, the exchange rate of the New Taiwan Dollar to the Japanese Yen reached 4.85, triggering a new wave of currency exchange. Many people are preparing to travel to Japan or allocate hedging assets, but they don't know which channels are the most cost-effective for exchanging currency. Today, we will break down the four most mainstream methods of exchanging Japanese Yen in the market, using real data to show you that choosing the wrong channel for the same 50,000 TWD could cost an extra 1,500-2,000 TWD.
Why talk about Yen exchange now?
The Japanese Yen is not just a travel currency; it also hides investment opportunities.
In terms of travel and consumption, most Japanese stores only accept cash (credit card penetration is only 60%). Whether shopping in Tokyo, skiing in Hokkaido, or vacationing in Okinawa, cash yen is required. Those purchasing Japanese cosmetics, clothing, or anime merchandise often need to pay directly in yen to Japanese websites or agents.
In the financial investment sphere, the Yen is one of the world's three major safe-haven currencies (alongside the US dollar and Swiss franc).

The Federal Reserve's rate cut expectations boost bond yields, leading to a reassessment of global government bonds
Traders' expectations of a rate cut announcement after the Federal Reserve's meeting next week have reached a high of 87%. The market generally predicts that the December meeting will initiate a rate cut cycle, with two more adjustments possible next year, and the final policy rate is expected to fall back to the 3.00%-3.25% range. However, the current market presents a puzzling contradiction—despite rising expectations of rate cuts, global bond yields are collectively increasing.
The 10-year U.S. Treasury yield has broken through 4.15%, the 10-year Japanese government bond yield has reached 1.97%, and the German 10-year bund yield has climbed to 2.81%. This rise in government bond yields across the U.S., Japan, and Europe reflects investor concerns over the Federal Reserve's independence, the Bank of Japan's rate hike expectations, and the U.S. fiscal dilemma. Market risks are evidently not to be underestimated.

Overvaluation Difficult to Sustain, S&P 500 Faces Adjustment Pressure
As of mid-November, the S&P 500 index has pulled back from recent highs and is currently oscillating around the 50-day moving average, with short-term daily volatility noticeably increasing. More notably, in terms of valuation, the current P/E ratio of the S&P 500 is about 24 times, which is over 15% higher than the average of the past five years. This indicates that the premium for technology and artificial intelligence themes has become quite substantial.
Analysts point out that if the technology sector lacks new fundamental support in the short term, the index may repeatedly consolidate within the 6,500 to 6,800 point range, forming a broader sideways pattern. This is not a sign of a crash but a necessary process for market digestion of previous gains and re-pricing.
Fed Policy Shift Becomes Key, Rate Risk Still Needs Vigilance
Federal Reserve official Waller recently stated that a rate cut in December is reasonable from a policy perspective, but this does not eliminate
