I have been paying close attention to the Japanese stock market recently and have noticed that many people still have some misunderstandings about the Nikkei 225. Rather than saying it is Japan’s S&P 500, it’s better to say it has its own unique character — it is price-weighted rather than market-cap weighted, and this difference can lead to noticeable volatility variations.
First, let’s talk about why it’s worth paying attention to the Nikkei 225 now. From last year to this year, the Japanese stock market has experienced quite a few ups and downs, especially the crash in August last year, whe

Recently, many people have been asking why purchasing cryptocurrencies with a credit card always fails. Actually, there is a policy reason behind this. In 2022, Taiwan’s Financial Supervisory Commission issued a letter requiring banks to prohibit virtual asset platforms from being designated merchants for credit cards. In simple terms, Taiwan’s government does not allow direct credit card purchases of cryptocurrencies. The government’s main considerations are to prevent money laundering risks, control financial risks, and due to the recent high volatility in the cryptocurrency market and frequ

Recently, I’ve seen many beginners in the community asking about the difference between market orders and limit orders, so I’ve organized my understanding and want to share how these two types of orders actually work.
Simply put, a market order is when you’re in a hurry and buy or sell immediately at the current market price. A limit order is when you set a target price, and the trade only executes when the market reaches or drops to that price. To give a relatable example, a market order is like going to the vegetable market and buying at the main stall’s listed price directly; a limit order

Recently, while following the earnings season of companies across the market, I found that many investors are still a little confused about the timing of when financial results are released. Especially when the U.S. stock earnings week is approaching, if you don’t get the schedule in advance, it’s easy to miss important trading opportunities. Today, let’s sort out the logic behind how earnings are released for Taiwan stocks and U.S. stocks, so you don’t have to look up information everywhere every time.
Let’s start with Taiwan stocks. Taiwan’s financial reporting rules are actually quite stric

Recently, gold prices have hit new highs, and friends around me are asking how to play with gold savings accounts. I’ve been a veteran player of gold savings accounts myself, starting to accumulate when gold prices were low, and I’ve indeed made quite a profit now, but I’ve also stepped into some pits. Today, I’ll organize my insights.
Speaking of gold savings accounts, it’s actually just gold that doesn’t have physical form, only stored in a bank account. You deposit New Taiwan Dollars, and the bank exchanges it for grams of gold recorded in your account, which you can buy, sell, or withdraw

Recently, many investors have been discussing the timing of buying and selling dividend-excluded stocks, especially those who want to buy heavily before the ex-dividend date and sell after. Honestly, this idea seems simple, but the underlying logic is actually much more complex than it appears.
First, let’s look at an interesting phenomenon. If a company can consistently pay stable dividends, it usually indicates healthy cash flow and a solid business model. That’s also why Warren Buffett particularly favors high-dividend stocks; more than 50% of his asset allocation is in such stocks. But for

Recently, I’ve noticed that many novice investors still have a somewhat unclear understanding of bear markets, so I’d like to share my own perspective.
What exactly does a bear market mean? Simply put, it refers to a situation where asset prices fall more than 20% from their highs—this is called entering a bear market. Conversely, an increase of more than 20% from the lows is a bull market. This applies not only to stocks, but also to bonds, real estate, precious metals, and cryptocurrencies.
I’ve noticed that many people tend to confuse bear markets with market corrections. In fact, a market

Recently, while researching some small and medium-sized stocks, I found that many great companies simply cannot be found on mainstream exchanges. Later, I realized that these companies are traded in the OTC over-the-counter market. I think this is a topic worth discussing in depth, because many investors still have misunderstandings about over-the-counter trading.
First, we need to clarify what OTC is. Simply put, OTC means over-the-counter trading: investors do not trade on centralized markets such as stock exchanges. Instead, they buy and sell securities directly through banks, brokers, phon

Recently, I noticed a rather interesting phenomenon—gold prices have been hitting new highs for more than the past year, yet many people still don’t really understand the underlying logic; they just follow the news. After observing it myself, I think it’s necessary to sort this out.
The root cause of the gold rally isn’t anything like short-term inflation or panic, but rather deeper, structural changes. Think about it: 2022 was a watershed year. Before that, the market directly tied gold prices to the dollar and interest rates; afterward, factors like central banks buying gold, geopolitical de

I only recently studied the opening hours and trading rules of the Hong Kong stock market seriously, and I realized that my previous understanding was still rather one-sided. The Hong Kong Exchange (HKEX) is open every day from 9:30 to 16:00, but in fact there are auction periods around the official opening, which is quite important for anyone who wants to get ahead.
There is an auction stage 30 minutes before the market opens (9:00–9:30). It is divided into several shorter time windows. During the first 15 minutes, you can place orders and revise them as you like; after that, there are restri

Recently, more and more people around me are asking about cold wallets, which actually reflects a phenomenon—everyone's demand for self-custody assets is indeed increasing. To be honest, using hot wallets is convenient, but if you don't manage private keys and seed phrases properly, problems can easily occur; I've heard too many cases of coins being lost.
I myself only started paying real attention to cold wallets after experiencing a few scares. After all, storing long-term holdings on offline devices makes me feel much more at ease. But the problem is, there are many types of cold wallets on

Friends who have been paying attention to the US dollar exchange rate should have felt it—the expectation for the dollar’s ups and downs has been shifting again and again. Since 2024 began with rate cuts, many thought the US dollar would keep weakening. But after geopolitical conflicts escalated, there was a phase of rebound, and it’s still trading in a range between 90 and 100—this kind of standoff has lasted almost a year.
To be honest, the US dollar’s rise and fall isn’t that simple. Many people think it’s enough to just look at rate hikes and rate cuts. But that’s far from sufficient. Inte

Recently, I’ve been paying attention to the topic of liquidity mining and found that many investors still have quite a few misconceptions about it. Liquidity mining may seem complicated, but the core logic is actually one sentence — you provide liquidity, and the platform rewards you.
First, let’s talk about what liquidity is. Simply put, liquidity is how easy it is to buy or sell an asset. BTC has high liquidity, and can be traded at market price anytime; small-cap coins have low liquidity, and you might wait half a day for someone to match your order. Exchanges and DEX platforms need liquidi

I recently realized that my understanding of currency symbols is a bit messy, especially the euro symbol and the dollar sign—they look similar but actually represent completely different things. In fact, over 30 countries worldwide use the $ symbol; for example, USD is US$, CAD is C$, HKD is HK$, AUD is A$, and this helps to distinguish them clearly.
The most easily confused symbol is ￥, which Japan uses to represent the Japanese Yen, while China uses it to denote the Renminbi, so the correct notation should be CNY￥100 or JPY￥100. Another more special symbol is ฿, which in foreign exchange rep

Recently, I’ve been studying some special phenomena in the Taiwan stock market and found a type of stock called “disposal stocks,” which is quite interesting. In simple terms, these are stocks whose prices swing abnormally in a short period and whose trading volume explodes—stocks that are then blacklisted by the Taiwan Stock Exchange.
These stocks are added to a “special observation list,” and their trading activities are subject to clear restrictions. It’s not that you can’t buy or sell; rather, the matching time changes from being available at any time to occurring once every 5 minutes or e

Recently, while organizing information about US stock market opening hours, I found that many people still feel a bit unclear about it. In fact, today’s US stock market opening hours are related to the seasons. Since it’s already the end of May, daylight saving time is in effect. From Taiwan’s perspective, regular trading hours are 9:30 PM to 4:00 AM. If you want to catch pre-market trading, you need to start watching from 4:30 PM. During standard time, the clocks move back by one hour, becoming 10:30 PM to 5:00 AM. So every year in November and March, you should pay special attention to the t

Recently, the topic of silver has been very hot. I’ve noticed that many people are asking, “Does Taiwan have a silver passbook/savings account?”—something as convenient as a gold passbook. To be honest, Taiwan’s banking system currently doesn’t have such a product at all, including Taiwan Bank itself, which has publicly clarified this. However, that doesn’t mean there’s no other way to participate in silver buying and selling—in fact, the options are so plentiful that it can be a bit dizzying.
Let’s first talk about why silver has become so popular lately. Compared with gold, silver has severa

Recently, I helped a friend sort out the process of opening a stock account in Taiwan, and I found that beginners are really easy to be misled by transaction fees—but in reality, choosing a broker is much more complicated than you’d think.
To be honest, when I first started investing, I also only looked at transaction fees at first, and later I realized that this is basically not the main point. A convenient order-entry trading app, fast customer service responses, and a clear trading interface—these are the things you’ll use every day. The brokers I use now have similar fee levels, but the us

Recently, I noticed an interesting phenomenon: more and more people around me are starting to consider buying gold. This may be because, in recent years, geopolitical situations have been tense, inflation has continued to intensify, and everyone is looking for a reliable hedging tool. To be honest, gold does have that value, but many people still do not understand enough about how to buy it.
In fact, buying gold is far more flexible than you might think. Many people still stick to the old routine of “going to a jewelry store to buy gold bars,” but investing in gold has evolved into several dif
