Recently, I’ve seen a common question that many new investors ask: when a stock hits the limit up or limit down, can you still buy and sell? In fact, it’s a good question, because many people see the stock price chart turn into a straight line and think the market is closed—but that’s not the case.
Let me briefly explain what limit up and limit down are. Taiwan’s stock market regulations state that a single stock’s daily price movement cannot exceed 10% of the previous day’s closing price. For example, if TSMC closed yesterday at 600 NT dollars, today it can only rise as high as 660 and fall a

Recently, I’ve been looking at the copper commodity and noticed an interesting phenomenon. Copper is called “Doctor Copper,” and there’s a reason for that: its price trend almost perfectly reflects the real state of the global economy. Unlike gold—which is mainly a safe-haven asset—silver is half industrial and half safe haven. Copper is 99% driven by industrial demand, and that determines that its price-movement logic is completely different.
This year, copper prices have been fluctuating in a high range, at about $12,000 to $13,000 per ton. Last year, the increase was over 40%. Many people a

People who have been paying attention to the yen exchange rate recently should have noticed that the Japanese currency’s performance over the past few years really has been somewhat unusual. As the world’s third-largest reserve currency, the yen’s rise and fall actually reflects a very interesting economic phenomenon—one particular group’s behavior stands out as especially worth noting: the so-called “Mrs. Watanabe.”
First, let’s talk about the yen itself. It is the fiat currency issued by the Bank of Japan, and it has had a modern monetary system since 1871 during the Meiji Restoration. After

The last time I saw news related to triple witching day, I was wondering whether it would really stir up a big wave. As it turned out, Citigroup’s analysts said it wasn’t as frightening as some people feared—open interest is actually below historical levels, and traders’ positions are relatively neutral, so the impact of this triple witching day may be overestimated.
That said, some people are still on alert. After all, contracts worth several trillions are set to expire; whether they’re rolled over or closed out, it could spark a surge in trading volume.
What’s even more concerning is the

Recently, I’ve been observing market discussions and found that many people still have some confusion about what a bear market really is. Instead of passively waiting, it’s better to first understand what a bear market actually entails, so you can make more rational decisions during market fluctuations.
Let’s start with the definition of a bear market. Simply put, when asset prices fall more than 20% from their recent highs, it enters what is called a bear market. This logic applies not only to stocks but also to bonds, real estate, precious metals, and cryptocurrencies. A typical example is t

Recently, while organizing my trading notes, I rediscovered some old technical analysis concepts and realized that many people still don’t quite understand the head and shoulders top and bottom patterns. So I decided to整理一些自己這些年的心得，希望能幫大家少走點彎路。
First, let’s talk about the head and shoulders top, which is a bearish signal. Simply put, it’s when the stock price forms three relatively high points, called the left shoulder, head, and right shoulder. When the right shoulder fails to break through the previous high of the head, it indicates that the upward momentum is weakening. I’ve observed many c

I’ve been thinking about a question lately: why do some people actually make money when the stock market crashes? The answer lies in the VIX Fear Index.
Speaking of the VIX Fear Index, many people may have heard of it but don’t quite understand it. Simply put, it’s an indicator that measures market participants’ expectations of volatility over the next 30 trading days. It was created by the Chicago Board Options Exchange in 1993, so it’s also called the CBOE Volatility Index. The higher the VIX value, the more panic there is in the market; the lower the value, the calmer the market. That’s why

Recently, some friends asked me how to interpret the deviation rate, so I organized the core logic of this technical indicator.
Speaking of the stock market, the hardest thing to predict is actually human sentiment. Investors' expectations of prices directly influence market trends, and the Bias (BIAS) indicator is used to capture these expectation changes. In simple terms, the deviation rate measures how far the stock price deviates from the moving average line, expressed as a percentage.
Imagine a bumper harvest year in the agricultural market, where rice prices soar, and everyone thinks thi

I’ve been thinking about a question lately: why has inflation become the top concern worldwide in recent years? When I looked through the data, I finally understood that inflation’s impact runs far deeper than we think.
Simply put, inflation means money is becoming less valuable. This year, your 100 dollars can buy ten items; next year, it might only buy eight. This isn’t something new, but in the past few years it has definitely gotten worse. In 2022, the US CPI rose 9.1% year-over-year, reaching a 40-year high. Europe was even worse—at one point it exceeded 10%.
Why is this happening? At its

Recently, someone asked me about the GBP exchange rate, and it made me realize that many people’s understanding of the British pound is still stuck at the idea of “it has kept falling since Brexit.” In reality, the story of the GBP is far more complex than that.
First, let’s talk about some background. The GBP is the world’s fourth-largest trading currency, with daily trading volume accounting for 13% of the forex market, trailing only the US dollar, the euro, and the Japanese yen. But these years have not been easy for the pound. After the 2008 financial crisis, the GBP began its depreciation

Recently, many beginners have asked me, "Can I buy stocks that hit the daily limit and are locked?" Actually, this is a very good question because many people panic when they see the limit-up board and have no idea whether they can still operate. So I’ve organized some of my years of experience on this.
First, to be straightforward: hitting the limit-up does not affect trading, and hitting the limit-down also does not affect trading. But the key point is whether your order can be executed; this is what everyone really needs to understand.
Want to buy when a stock hits the limit-up? Sure, but d

Recently, someone asked me how to trade Taiwan index futures, so I decided to organize my own experience. Actually, Taiwan index futures are simply a tool to track the Taiwan stock market, divided into the Big Taiwan and Small Taiwan contracts. If you want to understand what the recent full quotes of Small Taiwan are, basically it’s checking the complete trading quotes for the nearest expiration month.
When I first started, I was most confused about why I needed to choose Taiwan index futures. Later, I realized that this instrument allows for long and short operations, leverage, long trading h

Recently, someone asked about the US stock market circuit breakers again, and I remembered experiencing that crazy month in 2020, when the market hit the limit down four times in a short period. Even Warren Buffett has only seen the market hit the limit five times in his lifetime. That was truly a rare event.
Talking about the US stock market circuit breakers, many people get scared just hearing about them. In fact, they are a protective mechanism of the market. Imagine when the stock market crashes sharply, and everyone is panic-selling, emotions completely out of control. At this moment, it’

Recently, an investor asked me how to make sure you don’t miss important earnings releases from key companies during the US stock earnings season. I found that many people actually don’t have a good grasp of the regularity of earnings announcement timing, so today I’d like to share some practical observations.
First, let’s talk about the US market. In the US, the earnings season usually starts to get busy about 15 days after each quarter ends. Large bank stocks kick things off first, and then comes the super earnings week for tech stocks. Taking Q1 2026 as an example: TSMC’s ADR will have its

The Federal Reserve’s recent moves are getting increasingly interesting. Last week, the decision was to keep interest rates unchanged at 3.5%-3.75%, which seemed to align with expectations on the surface, but the number of dissenting votes reached four—the most severe split since 1992. Some want to cut rates, while others believe inflation risks are too high; this internal rift is directly reflected in the market.
Driven by this hawkish tone, the U.S. Dollar Index rose 0.4% that day, and the dollar/Japanese yen surged to 160.47, hitting a new high since last July. Watching the yen continue to

Recently, many people have been asking if it's still possible to mine Bitcoin in 2026. I’ve compiled some thoughts to share with everyone.
First, it’s important to understand what Bitcoin mining is. Simply put, mining is when miners use mining machines to keep records for the Bitcoin network, and the system rewards you with BTC. This process is based on the "proof of work" mechanism, where miners need to perform calculations to find a hash value that meets certain criteria. Once successful, the new block is added to the blockchain, and miners receive a reward.
Speaking of the development of Bi

I have been paying close attention to the trend of the US dollar recently, especially how it will move in the second half of the year. To be honest, it’s now much harder to judge the dollar’s direction than before.
Last year, the Federal Reserve started cutting interest rates, and theoretically, the dollar should have weakened, but the actual situation is far more complicated. Employment data has remained strong, and inflation is sticky, so market expectations for rate cuts have been repeatedly adjusted. The current consensus is that the Federal Reserve will adopt a “slow, late, and cautious”

Recently, I looked at some data on the Australian dollar's trend and found an interesting phenomenon. What has happened to the Australian dollar over the past ten years? Many people share the same feeling — the Australian dollar seems to be getting weaker and weaker, with each high point lower than the last.
Speaking of the Australian dollar, it used to be the sixth-largest currency by trading volume globally, holding a significant position. But if you look at the full picture of its trend over ten years, from a high near 1.05 in early 2013 to around 2023, the AUD has depreciated by over 35%.

I’ve been watching the trend of the USD vs. Japanese yen lately. Honestly, the yen is still struggling in a weak range right now. From the beginning of the year until now, the USD vs. Japanese yen has basically been fluctuating back and forth between 152 and 160. As of last week, it has already approached 159. Many people are asking whether the yen will rebound.
Based on my own observations, the yen’s continued depreciation mainly has several reasons. First is the issue of the USD–JPY interest rate differential: U.S. interest rates are far higher than Japan’s, which leads everyone to borrow ye

Recently, some friends asked me about non-farm payroll data, and I realized that many people still have some confusion about this concept. Today, let's talk about what big non-farm and small non-farm actually are, and why investors pay so much attention to them.
First, let's discuss big non-farm, officially called NFP (Non-Farm Payrolls), which is the official data released monthly by the U.S. Bureau of Labor Statistics. It includes three key indicators: non-farm employment, employment rate, and unemployment rate, covering employment in both the private and government sectors. Basically, it re
