Is there anything you need to understand about the difference between common shareholders and preferred stock? Interest rates have started to decline, and now many people are looking for assets that provide fixed returns. Preferred stocks are back in focus again. But before investing your money, you need to know how these two types differ.

Let's start with the basics. Common stock is what most people are familiar with. When you hold common shares, you are a part-owner of the company, sharing the risks and rewards. High risk, but unlimited profit potential. The stock price can multiply many times if the business grows well. Dividends are variable and uncertain, depending on how much profit the company makes.

But the problem is, when the company performs poorly, common shareholders are at the bottom of the priority list. If bankruptcy occurs, creditors and preferred shareholders get paid first. Any remaining money (if any) goes to you. Sometimes, after investing, you end up with nothing. To compensate for the risk, you have voting rights at the shareholders' meeting—1 share equals 1 vote. You have the power to influence important company decisions.

Preferred stock is a different story. It combines features of bonds and common shares. Legally, you still own a part of the company, but practically, it’s more like a creditor. You wait for fixed dividends, such as 5% or 7% of the par value. Whether the company makes a profit or not, you are entitled to these dividends first, before common shareholders.

What’s better about preferred stocks? When bad things happen, your capital is returned before common shareholders. The risk is therefore lower. But what do you give up? You have no voting rights, no decision-making power. You are just a passive investor waiting for dividends.

There are many types of preferred stocks to watch out for. Some are cumulative, meaning if the company skips dividends in a year, the owed amount accumulates and must be paid later. Others are non-cumulative—if dividends are skipped, the owed amount is lost. Some can be converted into common stock, offering opportunities for profit from price differences. Others can be called back by the company if market interest rates fall.

Now, let’s look at a real example from the Thai market. The case of Krungthai Bank (KTB-P) is interesting. KTB common shares trade hundreds of millions of baht daily, but KTB preferred shares? Some days, trading volume might be zero or just a few dozen shares. If you buy KTB-P with a large sum because of higher dividends, and then one day you need cash, you might not be able to sell your holdings or might have to sell at a loss. This is the liquidity risk that is a major issue for preferred stocks in Thailand.

Another thing to watch out for is interest rate risk. The price of preferred stocks moves inversely to interest rates. Currently, as rates fall, preferred stock prices may rise. But if rates increase again, their prices could plummet because investors will sell to buy bonds offering better yields with less risk.

So, which one is better? It depends on your goals. If you are young, have time, and want to grow with the business, common stocks are the answer. Tolerate the volatility and try to convert your money into wealth.

But if you are retired or need steady cash flow for monthly expenses, preferred stocks might be more suitable. They offer reliable dividends, no need to monitor constantly, and lower risk. Just be cautious about liquidity—buy stocks with good trading volume, or you might not be able to sell when needed.

What you need to understand is, no asset is the best for everyone. There are only assets that suit your situation. Study deeply, understand the differences between common shareholders and preferred stock, and make your own decisions. Wealth will be yours.
