Recently, the U.S. stock market has been volatile, with the Nasdaq index falling 13% from its high. The stock prices of seven major technology stocks, represented by Nvidia, have suffered a heavy blow, causing many investors to fall into the unfavorable situation of being trapped in stocks due to market fluctuations. Do we have any way to deal with the strategy if the market does not rise or fall in the future?

近期美國股市波動較大,納斯達克指數從高點下跌了13%。 七大科技股,以英偉達爲代表的股價受到沉重打擊,導致許多投資者因市場波動而陷入股票的不利境地。如果未來市場不升不跌,我們有什麼應對策略呢?

At this time, in addition to waiting for the market to pick up, options can also be used as an effective risk management tool to mitigate or offset the losses caused by the decline in stocks.

此時,除了等待市場回暖外,還可以使用期權作爲有效的風險管理工具,以減輕或抵消由股票下跌造成的損失。

But we need to remember a premise: the company's fundamentals must be very solid, and there will be no risk of long-term revenue and profit declines.

但我們需要記住一個前提條件:公司的基本面必須非常堅實,沒有長期收入和利潤下降的風險。

The following are several common option strategies:

以下是幾種常見的期權策略:

1. If it is judged that the stock price cannot rise sharply for the time being and is prepared to hold for a long time, then continue to cover the call

1. 如果判斷股票價格暫時無法大幅上漲並準備長揸,則繼續進行看漲期權賣出

For example, assuming that an investor purchases Nvidia stock (100 shares) at $120, as of August 7, 2024, the current market price has fallen to $98.9. By selling a call option with an expiration date of August 23 and an exercise price of $120 (note that 1 option does not correspond to 1 share, but 100 shares), a premium of $67 is immediately obtained to reduce the loss of the position.

例如,假設投資者以120美元購買英偉達股票(100股),截至2024年8月7日,當前市場價格已經下跌至98.9美元。通過出售到期日爲8月23日,行權價格爲120美元的看漲期權(注意1個期權不對應1股股票,而是對應100股),立即獲得67美元的權利金,以減少頭寸的損失。

By the expiration date of the option on August 23, there are several situations (the following method simplifies the fees, and the actual situation needs to include the transaction fee):

到期日8月23日時,有幾種情況(以下方法簡化了費用,實際情況需要包括交易費用):

1) If Nvidia's stock price rebounds but remains below $120, the option will not be exercised, and the investor's option fee income is $58. For example, assuming that on August 23, Nvidia's stock price rebounds to $110, the investor's loss on the underlying stock is $1,000, that is, the final loss is $1,000-67=953.

1)如果英偉達的股價反彈,但仍然低於120美元,則該期權不會被執行,投資者的期權費收入爲58美元。例如,假設8月23日,英偉達的股價反彈至110美元,投資者在標的股票上的損失爲1000美元,即最終損失爲1000-67= 953美元。

2) If the stock price rises above $120, the option is likely to be exercised, and the investor needs to sell the stock at the exercise price of $120, which means that the investor will lose the profit of the continued rise in the stock price, but also compensate for part of the loss through the option fee income. For example, if Nvidia's stock price rebounded to $130 on August 23, the investor would need to sell at $120, and the underlying stock profit would be 0, thus achieving capital preservation; while the premium profit would be $67, which means the final profit would be $67.

2)如果股價上漲到120美元以上,期權可能會被行權,投資者需要以120美元的行權價格出售股票,這意味着投資者將失去股價持續上漲帶來的利潤,但也將通過權利金收入部分補償損失。例如,如果英偉達的股票價格在8月23日反彈到了130美元,則投資者需要以120美元的價格賣出,標的股票的利潤爲0,這樣就實現了資本保值;而權利金的利潤爲67美元,意味着最終的利潤是67美元。

3) If the stock price continues to move sideways and the investor continues to make similar covered call transactions, the accumulated option fees will make up for certain investment losses; for example, if the investor makes a covered call transaction once a month and the option fee earned for each transaction is $67, then after 12 months, if Nvidia's stock price still does not break through the strike price and hovers around $100, the accumulated profit from the option fee is $804, and the investor's underlying stock loss is $2,000, but after deducting the profit from the option fee, the loss is reduced to $1,196.

3)如果股價繼續橫向移動,投資者繼續進行類似的覆蓋式賣出期權交易,累計的期權費用將彌補一定的投資損失。例如,如果投資者每月進行一次看漲期權交易,並且每筆交易賺取的期權費是67美元,則在12個月後,如果英偉達的股票價格仍未突破行權價格並圍繞100美元徘徊,則從期權費用累計獲得的利潤爲804美元,而投資者在股票上的損失爲2000美元,但在扣除利潤後,損失減少到1196美元。

The risks and drawbacks of the Covered Call strategy are that the effective implementation of the Covered Call strategy often requires investors to hold a considerable number of stocks, because in the U.S. stock market, a standard call option contract represents 100 shares of stock. This means that in order to sell a call option, investors usually need to hold at least 100 shares of the corresponding stock. For Nvidia, 100 shares of Nvidia is equivalent to holding a position of $9,800. If it is not enough, we have other strategies, that is, we need to use technical analysis to perform some short-term operations ourselves.

Covered Call策略的風險和缺點在於,有效執行Covered Call策略通常需要投資者持有相當數量的股票,因爲在美國股市中,標準看漲期權合約代表100股股票。這意味着爲了賣出看漲期權,投資者通常需要持有至少100股相應的股票。對於英偉達來說,持有100股英偉達相當於持有9800美元的頭寸。如果不夠,我們有其他策略,即需要利用技術面分析自行進行一些短期操作。

2. Use stock volatility for trend trading

2. 利用股票波動進行趨勢交易

For stocks with extremely high liquidity and volatility such as Nvidia, if a short-term trend is assumed, technical indicators can be used to try to reduce losses through active trend trading.

對於英偉達等極具流動性和波動性的股票,如果假定有短期趨勢,可以利用技術指標嘗試通過積極的趨勢交易來減少損失。

In short, the trend line trading method is to follow the general direction of the price of stocks or financial products to buy and sell.

簡而言之,趨勢線交易方法是跟隨股票或金融產品價格的總體方向進行買賣。

The highs and lows on the price chart are connected into a line. The rising trend line is connected from low to low, indicating that buyers are dominant and suitable for buying when the price pulls back to the trend line;

價格圖表上的低點和高點被連接成一條線。上升趨勢線從低點連接到低點,表示買家佔優勢,適合在價格回撤到趨勢線時購買;

The falling trend line connects the highs, showing that the sellers are strong, and you can consider selling when the price rebounds to the trend line.

下降趨勢線連接高點,顯示賣家強壯,可以考慮在價格反彈到趨勢線時賣出。

If the price breaks through the trend line, it may indicate a trend reversal:

如果價格突破趨勢線,可能表示趨勢反轉:

The rising trend line is broken, which is a sell signal;

上漲趨勢線被突破,這是一個賣出信號;

The falling trend line is broken, which is a buy signal.

下降趨勢線被突破,這是一個買入信號。

Since technical analysis relies more on psychology, in technical analysis, short-term trends generally only have the best trading effect when they touch the trend line for the first time, and the second time is weaker. Moreover, more people need to pay attention to the trend line, and the effect will be better. We can see that in the ups and downs of the market, if you find the most suitable trading node in a certain range, you will effectively complete the trend trading. For example, the figure below is a 10-minute line. The trend line formed by the M5 (the average of the closing prices of the last 5 K lines) set by the 10-minute line is a strong moving average.

由於技術分析更依賴心理因素,在技術分析中,短期趨勢通常只有在第一次接觸趨勢線時才具有最佳的交易效果,第二次則較弱。而且,越多的人關注趨勢線,效果就越好。我們可以看到,在市場的波動中,如果在一定範圍內找到最合適的交易節點,就可以有效地完成趨勢交易。例如,下圖是10分鐘線圖。由10分鐘線設置的M5(最後0.5萬行的收盤價平均值)構成了強有力的移動平均線的趨勢線。

After confirming the trend direction, follow the trend to trade. Enter the market when the price breaks through the key resistance or support level. Or look for overbought or oversold signals and reverse trade when the price reaches extreme levels.

確認趨勢方向後,跟隨趨勢交易。當價格突破關鍵阻力或支撐位時進入市場。或尋找超買或超賣信號,並在價格達到極端水平時進行反向交易。

Using high-volatility stocks for intraday trading is an active strategy that can help investors find opportunities when stocks are trapped. However, intraday trading is a high-risk strategy suitable for experienced investors who can withstand market fluctuations. Secondly, if there is no trending opportunity, short-term range fluctuations can be used for trading.

使用高風險股票進行日內交易是一種積極的策略,可以幫助投資者在股票被困住時尋找機會。然而,日內交易是一種高風險策略,僅適合經驗豐富的投資者承受市場波動。其次,如果沒有趨勢機會,可以利用短期區間波動進行交易。

In addition, if it is assumed that the stock price fluctuates within a certain box, trend trading and other technical indicators can also be used to track it. We have many trading courses involving technical analysis in the moomoo classroom to assist everyone in trading.

此外,如果假設股票價格在一個特定區間內波動,可以使用趨勢交易和其他技術面分析因子進行跟蹤。我們在moomoo教室中有許多涉及技術面分析的交易課程,可協助大家進行交易。
