When it comes to stocks, most investors only buy shares if they think the company is growing strongly and the share price will rise. This is also called "bullish". Once you buy shares, they are yours - until you sell them again.
An interesting aspect of owning shares is that there is no limit to how high the price of a share can rise. You can sell the stock at any time when the market is open. If you sell the stock at a higher price than you paid for it, you make a profit. So trading shares is basically very black and white - the maximum loss is known at the time of the takeover and can be calculated by multiplying the number of shares purchased by the share price. In this sense the purchase of shares is quite capital intensive and you can only earn money if the share price rises. I'm sure I won't tell you anything new, you probably already knew that.
Of course, there is also the so-called short sale, i.e. the sale of shares that you do not actually own. As mentioned in the previous section, you are long when buying shares, because you assume that they will rise. Whether you like the company or believe that part of the company will drive up the price, you assume that you can buy now and hopefully sell later at a higher price.
As a seller, you accept the opposite side of this transaction. If you think that a company has reached its peak or is likely to decline in the future, you could benefit from a sellout with a short position. Selling something is also known as "short" in the investor's world. Short selling gives you the right to borrow shares and sell them at the current share price. In the best case, you sell the shares at the current price and buy them back later at a lower price. Since you want the stock to fall, you are “bearish”.
It is important to remember the risk of selling a stock. As with buying stocks, selling stocks short can be very expensive. The fact that there is no upper limit to the stock price is still true, but in this case it also means that there is no limit to the risk of losing a stock, as you may have to buy it back at a higher, undetermined value. Just like buying stocks, you have to be right about short positions to make money, so the stock has to move in the direction you forecast. If you sell 100 shares at 100 USD per share and this rises to 110 USD per share, you would have lost 10 USD per share because you sold it short. In this example, this would mean a total loss of 1,000 USD.
Most investors still regard equities as a long-term investment. Even if we decide to buy and sell them more often, it ties up a lot of capital, even in a margin account where you would normally only have to invest 50% of the value of the shares. At the same time, it is extremely difficult to determine the price direction of stocks correctly and consistently. This is one of the reasons why we trade options. Trading options allows us to change our attitude of "Where do I think this stock is going".
In contrast to many short-term equity transactions, trading an option is not just a 50/50 bet. Our option trading style allows us to choose different prices to become long or short stocks, known as strike prices. This allows us to make money even if we go straight in the wrong direction! We can make smarter trading decisions by setting clear goals and defining exit strategies. Since option strategies themselves usually require less capital than the equivalent of 100 shares, traders can use option strategies to do more with their money.
Enough talk, let's dive into the world of options and see what is really behind all that is said.
Remember:
Options offer significantly more application possibilities than pure trading in shares.
Thus strategies can be adapted/selected rather to the own opinion.
Options benefit from the leverage effect and tie up less capital.
Options should under no circumstances be confused with warrants or other derivatives such as knock-outs.
2. Basics
2.1 Main Features of Options Contracts
I think it's really important to understand the basics of something before you go into depth. No one is helped to build a house on a shaky foundation. That is why I am going to go over the characteristics of option contracts here.
An option contract consists of several components. First, the actual share on which we want to write options. Since these are not always equities, but can also be futures, we will use term underlyings. This could be an ETF ETN ETC / Futures or any other tradable product. So, first we choose the one we want to trade. All the following factors depend on this basic selection. The second part is the expiration date. As the name suggests, this is the day on which the option contract ends. Usually such an expiration date is always the third Friday in every month. Nevertheless, there are exceptions, for example, some underlyings have an expiration date every Friday, while the SPY (= ETF on the S&P 500), for example, has an additional two-day and quarterly expiration date. Futures are a bit different again, but they are not the subject of this book. For the sake of simplicity, however, we will be recording the third Friday of the month. So now we know which stock we want to trade in which cycle.
The third part of the contract is the strike price. This is the price at which you agree to either buy or sell the underlying shares in the future. Remember, this is not the price at which the stock is being traded. Let's say the underlying is trading at 50 USD. You are not forced to choose this price, but can say, for example, that you would only be willing to buy shares at 40 USD. The fourth part of the option contracts may seem a bit abstract at first, but you've already got to know it. This is the choice of "type". This simply depends on whether you want to trade call or put options. Basically there are only these two types - calls or puts. The big difference lies in how, in what way and in what relation to each other you use them so that they can unfold their full effect.
The last and fifth part of an option contract is the premium paid or received by the contracting parties. Remember, if you are an option buyer, you would pay a premium for this option contract in this case. If you are an option seller, you would receive the corresponding premium. That much has already been said at this point. You usually want to be on the option seller's side, collect premium and not spend them.
Premiums and options contracts usually have a 100-point multiplier (except for futures, for example). For example, if you see a premium of 1 USD, the actual value of the contract is 1 USD per share * 100 shares, or 100 USD. The displayed price refers to the premium for one share. An option contract always consists of 100 shares, therefore the multiplier comes in play.
In the course of time, we will get to know each of these components in greater detail, so that at some point an understanding of the big picture will emerge. Otherwise you will also have the opportunity to go back a few pages at any time and read them again.
Option-Chain
The above-mentioned information must now be presented in a clear manner so that every reader can understand and comprehend it. Also, I've already told you that it's possible to trade options without ever having to see a chart. To do just that, there is the so-called option chain.
An option chain is a matrix list for a single underlying that displays all puts, calls, strike prices and price information for a specific expiration period. The majority of online brokers and stock trading platforms display option prices in the form of an option chain with real-time or delayed data. The chain display enables fast scanning of activities, open interest rates and price changes. Traders can find out about the specific options required to fulfill a particular option strategy.
You can quickly find the trading activity of an asset including trading volume, premiums by strike price and expiration months. The data can be sorted by expiration date, most likely to the farthest away, and then further refined by exercise price - basically, in most applications, you are free to design your "chain" as you wish.
