We are hoping this to be an easy and simple lesson to introduce options to you. By following Options Basics' articles, you should be able to understand options and how to utilize options to either profit or protect your stock. 

我們希望這是一堂簡單易懂的課程,可以向你介紹各種選擇。通過閲讀期權基礎知識的文章,你應該能夠理解期權以及如何利用期權來獲利或保護你的股票。

Today we will be talking about the advantages and disadvantages of options. Even though many of you already have experience trading options, it is still good to know if there is any other way to utilize options trading to your advantage. 

今天我們將討論選項的優點和缺點。儘管你們中的許多人已經有了交易期權的經驗,但知道是否有任何其他方法可以利用期權交易對你有利,這仍然是一件好事。

Let's start with the advantages of options trading

讓我們從期權交易的優勢開始吧

The advantages of options mainly include two parts:

期權的優勢主要包括兩部分:

Part 1. Making more money

第一部分:賺更多錢

Generally, there are two ways to make money trading options.

一般來説,交易期權有兩種賺錢方式。

Firstly, options can act as a leverage, it lets you gain big with a relatively small amount of money invested. (Of course, more reward implies more risk so please do not get too excited!)

首先,期權可以起到槓桿的作用,它讓你用相對較少的資金獲得巨大收益。 (當然,更多的回報意味着更多的風險,所以請不要太興奮!)

Let's pick a random stock and an option related to demonstrate this:

讓我們隨機挑選一隻股票和一個相關的期權來演示這一點:

20210607000096256facfc55e2e.png

Here is a screenshot of NIO yesterday. It closed at $42.35 a share and was up 12.3%.

這是昨天蔚來的截圖。該股收盤報每股42.35美元,上漲12.3%。

If I bought 100shares when the market opened, I would have invested $38.78(opening price)*100shares=$3,878.

如果我在開盤時買了100股,我會投資38.78美元(開盤價)*100股=3,878美元。

If I had sold them when the market close, I would have gotten $42.35*100shares=$4,235.

如果我在股市收盤時賣出它們,我會得到42.35美元*100股=4,235美元。

My profit would be $4,235-$3,878=$357, which was 12.3% of my total investment.

我的利潤是4,235-3,878美元=357美元,佔我總投資的12.3%。

Now let's see if we invested in options instead, what would happen.

現在讓我們看看,如果我們轉而投資期權,會發生什麼。

Since our purpose is to demonstrate the difference between investing in options or the underlying stock, I picked a random option as an example.

由於我們的目的是演示投資期權和標的股票之間的區別,我選擇了一個隨機期權作為例子。

If I bought 1 contract (which stands for 100 shares of the underlying) of the above options at the opening of the market, it would cost me $1.43(opening price)*100=$143.

如果我在開盤時購買上述期權中的一份合約(相當於100股標的股票),我將花費1.43美元(開盤價)*100=143美元。

And just like the previous example, if I had sold this options contract when the market close, I would have gotten $3.15*100=$315.

就像前面的例子一樣,如果我在市場收盤時賣出這份期權合約,我會得到3.15美元*100=315美元。

My profit would be $315-$143=$172, which was 111.41% of my total investment.

我的利潤是315-143美元=172美元,佔我總投資的111.41%。

Now let's compare the two examples above.

現在讓我們比較上面的兩個例子。

If we had gotten 2 options contracts, we would have made around the same amount of dollars we made by investing in the underlying stock. This means by investing $286 in the option above, we would have made the same amount of money as if we invested $3,878 in the underlying stock.

如果我們獲得了兩份期權合同,我們將獲得與投資標的股票大致相同的美元。這意味着,通過在上面的期權上投資286美元,我們將獲得與我們在標的股票上投資3,878美元相同的金額。

Secondly, options can provide a steady stream of income.

其次,期權可以提供穩定的收入來源。

For example, if I currently hold 100 shares of NIO in my portfolio, and I believe that NIO stock prices will not go up in the near future(either consolidation or decline). I could sell 1 call contract of NIO and earn the call option premium. 

例如,如果我目前在我的投資組合中持有100股蔚來,我相信蔚來的股價在不久的將來不會上漲(無論是盤整還是下跌)。我可以賣出1份蔚來看漲合約,賺取看漲期權溢價。

Part 2. Hedging risk

第二部分:對衝風險

In options trading, we can utilize options combination, which is also called the options strategy, to control or lower the amount of risk we are taking on.

在期權交易中,我們可以利用期權組合,也稱為期權策略,來控制或降低我們所承擔的風險量。

Options strategies will be introduced in detail later. 

期權策略將在稍後詳細介紹。

A simple example would be the example earlier about selling call options.

一個簡單的例子就是前面關於賣出看漲期權的例子。

If NIO price drops, we would be taking losses since we own 100 shares in our portfolio, but it will be made up by the call option premium that we earned by selling call options of NIO.

如果蔚來價格下跌,我們將蒙受損失,因為我們的投資組合中有100股,但這將由我們通過出售蔚來看漲期權賺取的看漲期權溢價彌補。

Now the disadvantages of options!

現在選擇的缺點是!

The buyer of options can lose 100% of their investment, and the seller of the option can lose up to all the money they have in their account. 

期權的買家可能會損失100%的投資,而期權的賣家可能會損失他們賬户上的所有資金。

For example, if I bought 1 contract of the NIO call option that we've mentioned before, and the stock did not go as we had predicted, the value of the option that I held will eventually reach $0 as time get closer to the expiration date.

例如,如果我購買了我們之前提到的蔚來看漲期權的1份合約,而股票沒有像我們預測的那樣走得更遠,那麼隨着時間越來越接近到期日,我持有的期權的價值最終將達到0美元。

So, the worst outcome is that I lose $143, which is the amount I paid for the option.

所以,最糟糕的結果是我損失了143美元,這是我為期權支付的金額。

However, if I am the seller of the option, this will not be the case. As the stock price swings up and down, my margin will be affected, and once my account balance is lower than the margin needed, I will be receiving a margin call. And if I am unable to add funds to maintain our margin level, I will suffer a margin closeout.

然而,如果我是期權的賣家,情況就不會是這樣。隨着股價的上下波動,我的保證金將受到影響,一旦我的賬户餘額低於所需的保證金,我將收到追加保證金通知。如果我無法增加資金來維持我們的利潤率水平,我將遭受利潤率關閉的痛苦。

Okay! This is about everything for today!

好吧!這就是今天的一切!
