I have just delved deeply into options and want to share some interesting things I discovered. If you've ever wondered what options are and why they are considered a "hedge" for your investment portfolio, this article might help.

Simply put, what is an option? It is a contract that gives you the right (but not the obligation) to buy or sell a certain asset at a predetermined price on a specific future date. Unlike futures, you are not forced to execute it. If there is no profit, you only lose the premium fee.

The interesting part is that you can make a profit even when the market goes down. For example, if you buy a put option on VN30 with an exercise price of 1,200 points, and the market crashes to 1,000 points, you can still sell at 1,200. That’s why options are called risk management tools or hedging instruments.

I see there are two main types: call options (the right to buy) when you believe prices will rise, and put options (the right to sell) when you fear prices will fall. Each type has three states: in the money (profitable), at the money (break-even), or out of the money (loss). This classification is very important to understand what an option is in practice.

What about actual trading strategies? I found some common ones. Covered call is when you hold stocks and sell call options on them. This helps generate additional income in sideways markets. Married put is when you buy stocks and buy put options as insurance against downside risk. Long put simply means buying a put option, expecting the market to decline.

However, it must be acknowledged that what options are also come with significant disadvantages. Transaction fees can be quite high, and margin requirements are substantial. If you are a writer (seller), potential losses can be unlimited. Moreover, it’s quite complex with many technical terms, not an ideal choice for beginners.

In Vietnam, options trading on the stock market has not been widely developed. Currently, only VN30 futures are permitted. To trade options, you need to turn to international platforms like Forex brokers. When choosing a platform, make sure it is regulated by reputable international authorities such as ASIC, CySEC, or CIMA.

I’ve seen some real cases. If you hold a stock portfolio worth 2 billion VND in banks but worry about rising interest rates, you could allocate 2% of your capital (40 million VND) to buy VN30 index put options. If the market drops 15%, your portfolio loses 300 million, but the put options could profit 400-500 million thanks to leverage. Conversely, if the market rises, you only lose the 40 million premium, while your portfolio grows significantly.

Compared to warrants (CW) and futures, options have the advantage of being very flexible with hundreds of strategies, while CW are more passive and futures require higher margin. However, transaction fees for options can be cheaper if you choose the right platform.

In general, what makes options a powerful tool for investors? It’s a way to optimize profits, manage risks, and have more opportunities than traditional trading. But remember, it’s not for beginners. You need to learn thoroughly, start small, and focus on assets you understand well. Having a clear strategy and sticking to it is the key to success.
