Understanding the Core Value of Network Communication Concept Stocks
The network communication industry is rapidly expanding under global policy-driven initiatives. Since 2023, network communication concept stocks have performed remarkably, with gains exceeding 35%. But what exactly are network communication concept stocks? Why are they worth paying attention to?
Network communication concept stocks refer to publicly listed companies engaged in network communication-related businesses, covering various fields such as hardware equipment manufacturing, communication chips design, and telecommunications services. Common devices include routers, switches, wireless communication devices, and more. According to Dell'Oro data, the global communication equipment market size reached nearly $102 billion in 2022, maintaining growth for five consecutive years, and is expected to surpass $120 billion by 2025.
The industry chain extends from upstream component suppliers (microprocessors, network ICs, printed circuit boards, etc.) to downstream end-users (wireless communication devices, telecom service providers, fiber optic communication equipment, etc.), forming a complete ecosystem.

The largest financial market in the world is not stocks or bonds, but the foreign exchange (Forex) market. With a daily trading volume of over $6 trillion, currency exchange transactions between countries remain highly active. In recent years, even traditionally stable and mature market currencies have experienced noticeable fluctuations, creating numerous opportunities for ordinary investors.
For beginners interested in participating in currency trading, the most important thing is to understand the nature of the exchange rate spread and to master trading methods that match their risk tolerance. This article will delve into the core logic of currency investment, five practical tips, and various trading schedules to help you find your own profit path.
What is the core profit in buying and selling foreign currencies?
Simply put, buying and selling foreign currencies mainly aims to profit from the exchange rate spread. The spread is the difference in the exchange rate of the same currency at different times or through different channels. Investors profit by predicting currency trends and using strategies like "buy low, sell high" or "sell high, buy low."

Why should you learn about foreign exchange trading?
Many Taiwanese investors face the same dilemma: bank fixed deposits offer only a 1.7% interest rate, and asset depreciation is happening faster than savings grow. That’s why more and more people are turning to foreign currency investments. Compared to local savings, foreign currencies not only provide higher interest income but also allow capital appreciation through exchange rate fluctuations.
The appeal of foreign currency trading lies in its unique two-way trading mechanism. Unlike stocks, which can only go up, the foreign exchange market allows investors to profit from both rising and falling prices. Additionally, the global forex market operates 24 hours a day without interruption, enabling investors to adjust their strategies at any time based on market changes. This flexibility is unmatched by traditional investment methods.
From a risk management perspective, holding multiple currencies can effectively hedge against the depreciation risk of a single currency. When the domestic currency faces downward pressure, foreign currency assets can protect your wealth from shrinking.

Want to master how to read MA lines? This guide will help you clarify everything. The moving average line is one of the most commonly used technical indicators by traders, but many people only know part of it. This article will break down the essence, classification, calculation, parameter selection, and practical application of MA lines to explain how to use this "magic tool" in detail.
What is an MA line? Explained in one sentence
The moving average (Moving Average, abbreviated as MA or "average line") is very simple in essence: summing the closing prices of the past N days and dividing by N gives the N-day moving average.
Formula: N-day moving average = Total closing prices over N days ÷ N
Over time, each day produces a new average value. Connecting these averages results in the MA line we see. For example, a 5MA is the average of the closing prices of the most recent 5 trading days.
What is the purpose of this line? It can help you quickly determine the short-term, medium-term, and long-term price trends, find

On December 10, 2025, the NT dollar against the Japanese Yen reached 4.85, reigniting interest in travel to Japan and Yen investments. But exchanging Yen isn't just a matter of visiting a bank; choosing the right exchange method can save you thousands of dollars. We have compiled the latest four currency exchange channels and their actual costs to help you find the most cost-effective solution.
Why is it worth exchanging Yen now?
Three major needs: travel, consumption, and investment
In Taiwan, the practicality of the Yen far exceeds that of other foreign currencies. From everyday shopping in Tokyo, skiing in Hokkaido, to vacations in Okinawa, Japanese merchants still primarily use cash (credit card penetration is only 60%). Additionally, those who like to purchase Japanese cosmetics, clothing, and anime merchandise, as well as students planning to study abroad and work part-time, need to plan their Yen exchange in advance.
On the financial side, there is even more to watch— the Yen is one of the world's three major safe-haven currencies (alongside the US dollar and Swiss franc), providing hedging benefits during Taiwan stock market fluctuations. In 2022, Russia

Recently, the Japanese Yen against the US dollar hit a new low, and the Euro against the Yen reached a historic low, indicating the widening US-Japan interest rate differential and the potential for Japanese authorities to intervene. The market is focused on possible policy actions by the Japanese government and upcoming economic stimulus plans, while also analyzing the future trend of the Yen and the performance of other Asian currencies. Predictions suggest that the Yen has limited room for short-term adjustment, but the chances of policy intervention are gradually increasing.

From 2024 to 2025, international gold prices will hit record highs, driven by factors such as trade policy uncertainties, shifts in monetary policy, and increased central bank gold reserves. Although the market remains attractive, investors should cautiously manage volatility risks and make informed decisions based on their risk preferences. The long-term outlook for gold remains optimistic, and major investment banks are also optimistic about future price increases.

Amazon announces plans to invest an additional $35 billion in India by 2030, focusing on AI-driven digital transition, export growth, and job creation.

The Reserve Bank of Australia's easing cycle may be nearing its end, as November inflation data unexpectedly rose to 3.8%. The market expects interest rates to remain unchanged in December, while upward pressure on rate hikes is gradually emerging. Analysts predict that more tightening policies may be needed by 2026, and the AUD/USD continues to rise, indicating a positive outlook for the Australian economy.

The recent trend of the NASDAQ has attracted widespread market attention. After reaching a record high, the index is undergoing a deep structural test during its correction. Currently, the NASDAQ stands at 23,214.69 points, up 4.2% for the week. However, behind this impressive performance, there are valuation risks and shifts in capital flows that investors must face.
False Hope of Short-term Rebound: Rate Cut Expectations vs. Valuation Reality
The four major US indices have recently moved in tandem, with the NASDAQ leading the gain by 0.8%, driven mainly by two factors. First, the decline in US Treasury yields has increased the attractiveness of bonds. Second, market expectations for a rate cut in December have risen sharply—currently priced in at 80–85%. This expectation gap has historically been a driving force behind the rise of technology and growth stocks.
However, a deeper contradiction is emerging.
According to the latest corporate earnings data, the contribution of the technology sector to overall corporate profits is 20.

In the foreign exchange market, many investors tend to focus on mainstream currencies such as the US dollar and euro, while overlooking some emerging market currencies with high volatility characteristics. The South African Rand (ZAR) is such an asset, full of trading opportunities but also risks, and has gained popularity among investors in Taiwan in recent years. So, is exchanging South African Rand for US dollars really cost-effective? We need to analyze this from multiple dimensions.
Basic Attributes and Characteristics of the South African Rand
The Rand is the official currency of the Republic of South Africa, issued by the South African Reserve Bank (the central bank). South Africa officially adopted the Rand as its currency unit in 1961. In 1974, it implemented a managed floating exchange rate system, and in 1995, it abolished the dual exchange rate system, transitioning to a single exchange rate system.
The South African Rand differs from typical national currencies; it is widely defined as a risk asset currency. This special attribute means that the Rand's exchange rate fluctuations are highly tied to global risk appetite—when the country

Silver Market Analysis
The silver market is set to experience a strong rally in 2025. On December 9th, London spot silver prices broke through the $60 per ounce mark for the first time, and then continued to climb, reaching a historic high of $64.6 per ounce. So far this year, silver has gained over 100%, making it one of the best-performing assets.
The recent surge is mainly driven by expectations of Federal Reserve rate cuts, tight global silver supply, and the U.S. government listing silver as a critical mineral, among other positive factors. Compared to gold, which has increased by over 60%, silver's rally has outperformed by a significant margin, and it has also led the Nasdaq Composite Index by about 20%, highlighting its outstanding performance in asset allocation this year.
International investment bank UBS is even more optimistic about the future, raising its target price for silver in 2026 to the range of $58 to $60 per ounce, and not ruling out the possibility of a further surge to $65 per ounce.

The Renminbi (RMB) welcomes a turning point, with signs of appreciation already evident
Since 2025, the RMB exchange rate has shown a clear turnaround. The USD to RMB has fluctuated bidirectionally within the 7.04-7.3 range, appreciating approximately 3% over the year. By mid-December, the RMB against the US dollar strengthened past the 7.05 mark, reaching a high of 7.0404 so far, the highest in nearly 14 months. This change breaks the depreciation trend of the past three years, and the market is beginning to reassess the medium-term outlook for the RMB.
The offshore RMB (CNH) has also performed remarkably. Trading more freely in international markets, CNH has fluctuated between 7.02 and 7.4 this year, reacting faster and better reflecting global investors’ true views on the RMB. From a high of 7.36 at the start of the year, CNH has rebounded over 4%, indicating a shift in international capital sentiment.
Why did the RMB suddenly rebound? Three major drivers are gaining momentum

Why are traders all using Fibonacci indicators?
When it comes to the most practical technical analysis tools in the forex market, Fibonacci indicators are definitely among the top. This set of indicators originates from an ancient mathematical concept—the golden ratio, which is believed to be the perfect proportion that describes the operation of all things in nature. Interestingly, this magical ratio not only exists in the natural world but also appears mysteriously in the price fluctuations of financial markets.
The name Fibonacci comes from the Italian mathematician Leonardo Pisano, who in the 13th century introduced this golden ratio, originating from Indian mathematics, to the Western world. To this day, traders have evolved this ancient mathematical concept into a comprehensive trading strategy system used to identify potential reversal points in asset prices.

Recently, international oil prices have rebounded due to supply concerns, with Brent crude around $63.31 per barrel. OPEC+ has decided to maintain production levels, reflecting a conservative market outlook on weak demand. Geopolitical events have also pushed up oil prices, but the short-term risk premium is unlikely to be sustained. In the long term, global economic slowdown and structural contradictions may lead to a decline in oil prices again, and investors should exercise caution.
