Is it certain that opening an account with a securities firm can make money? Is buying AI necessarily profitable? What is the most suitable for beginners to buy? Recently, there have been many tutorials on securities firms or deposits and withdrawals on X, as if opening a successful account means making money. But is this really the case? Although AI is very popular now, it does not necessarily mean that buying AI concept stocks will lead to profits, nor does it mean that buying at any price is reasonable. The US stock market is essentially a risky asset, and popular industries may also experience a pullback. Excellent companies may also have limited upward potential, and not all investors have a clear understanding of the target they want to buy. Currently, with the popularity of AI, computing power, storage, power, data centers, and semiconductor equipment may all be growth points in the future. But for many friends who have already risen five or six times, they are not very willing to buy. Those who have not risen are worried that their fundamentals are not strong enough. When they see the rise of Hynix, they feel that it is too high and want to chase other storage sectors. When they see the rise of Nvidia, they feel missed and want to find the "next Nvidia". But the hardest part of investing is here, truly good companies are often not cheap, and cheap companies may not necessarily have real opportunities. If ordinary investors do not have sufficient industry research capabilities, it is easy for them to switch back and forth between different concepts, and eventually become chasing after the rise and killing the fall. So for some novice friends, the most suitable approach is not to heavily invest in AI stocks from the beginning, nor to study which stocks will double every day, but to start with the index. For example, broad-based indices such as the S&P 500, Nasdaq 100, and the All Market Index are essentially a basket of companies used to diversify risk. Of course, the index can also fall and is not a guaranteed profit, but compared to betting on a single AI stock, the index is more beginner friendly, the volatility is relatively easier to bear, and it is also more suitable for long-term investment. It should be noted that if you are buying index ETFs in the US stock market, such as VOO, SPY, IVV commonly seen in the S&P 500, and QQ ETFs commonly seen in the Nasdaq 100. For many non US tax residents, buying such ETFs directly usually involves US withholding tax on dividends, and if the holding amount is large, it may also involve US inheritance tax related issues in the future. If you want to reduce this tax issue, you can consider equivalent standards in other countries. For example, if you want to buy the S&P 500, you can study standards such as CSPX and VUAA. If you want to buy Nasdaq 100, you can study targets like CNDX. The biggest difference between these targets and VOO and QQ is the location of fund registration and tax structure. For example, CSPX also tracks the S&P 500, but it is not a US registered ETF, but a UCITS ETF registered in Ireland. For some non US investors, holding such ETFs for the long term may be more suitable than directly buying US registered ETFs. Of course, buying CSPX, VUAA, or CNDX does not mean that there is no tax at all, but structurally speaking, it may be lower than the pure ETF tax in the United States. For example, for Chinese users, the United States only deducts 15% at the fund level (reflected in the net asset value growth of ETFs), which is half as much as the 30% deduction required to buy VOO or QQ directly. There is another detail here. If you are planning long-term investments and do not require cash dividends, you can prioritize the accumulation ETF, also known as Accumulating. This type does not directly distribute dividends to your account, but rather reinvests within the fund, making it more suitable for long-term compounding and lazy investors. On the contrary, if you need cash flow and want to receive regular dividends, you can look at dividend ETFs, also known as Distributing. But for most novice investors, if the goal is to accumulate assets in the long term rather than relying on dividends to make a living, the accumulation type will be simpler. So my personal suggestion is that beginners can start by buying indices with small funds, in batches, and through regular investments. First, familiarize yourself with market fluctuations and know how you react when your account falls. Then, slowly consider whether to take a small portion of your position to buy topics such as AI, chips, storage, and electricity.
