About the Dow Jones Index

The Dow Jones Industrial Average (DJIA), also known simply as the Dow, is a stock market index that consists of 30 publicly traded companies in the United States. The index is named after Charles Dow and Edward Jones, who founded Dow Jones & Company in 1882. The companies that make up the Dow are considered to be a representation of the broader U.S. stock market and are chosen by the editors of the Wall Street Journal.

The Dow is a price-weighted index, which means that the companies with the highest stock prices have the greatest impact on the index. For example, a 1% increase in the stock price of a company with a high stock price will have a greater impact on the Dow than a 1% increase in the stock price of a company with a low stock price. This differs from market-capitalization weighted indices, such as the S&P 500, where companies with larger market capitalization (the total value of a company's outstanding shares) have a greater impact on the index.

The Dow has a long history as a benchmark for the U.S. stock market. It was created in 1896 and is the second-oldest U.S. stock market index, after the Dow Jones Transportation Average which was created in 1884. Over the years, the Dow has gone through several changes to its composition, with various companies being added and removed from the index. The current 30 companies that make up the Dow represent a wide range of industries, including technology, finance, healthcare, and consumer goods.

The Dow is considered to be a barometer of the U.S. economy, and its performance is closely watched by investors and analysts. The Dow is known for its volatility, with the index often experiencing large gains and losses in a short period of time. This volatility is due in part to the fact that the Dow is made up of only 30 companies, compared to the S&P 500 which is made up of 500 companies. Because of this, the Dow can be affected more dramatically by the performance of a single company than the S&P 500.

The Dow has a long history of reaching new all-time highs, with the index breaking the 1,000-point barrier in 1972, the 10,000-point barrier in 1999, and the 20,000-point barrier in 2017. However, it's worth noting that the Dow's performance can also be affected by external factors such as political and economic events, including recession, war, interest rates, and inflation.

Despite its limitations, the Dow is still widely followed and quoted in the media as an indicator of the overall health of the U.S. stock market. While it may not be the most accurate representation of the U.S. stock market, the Dow's long history and the fact that it is made up of some of the largest and most well-known companies in the U.S. makes it a valuable benchmark for investors.

In conclusion, the Dow Jones Industrial Average, or the Dow, is a stock market index that tracks the performance of 30 publicly traded companies in the United States. It is a price-weighted index, which means that the companies with the highest stock prices have the greatest impact on the index. The Dow is considered a barometer of the U.S. economy, and its performance is closely watched by investors and analysts. Despite its limitations, the Dow's long history and the fact that it is made up of some of the largest and most well-known companies in the U.S. makes it a valuable benchmark for investors.

投資小叮嚀

順勢操作切記別跟市場做對

01

當股價站上成本線方可順勢加碼操作,切記不要加碼攤平

02

注意盤勢的量價關係,當出現新的型態務必重新規劃交易計畫

03

當股價跌破成本線或重要支撐點,務必調整手中持股,重新規劃交易

Faq

何謂量價關係

量,指的是一檔期貨商品單位時間的成交量,其中包含有日成交量,月成交量,年成交量等;價,指的是一檔期貨商品的價格,以收盤價為準,還有開盤價,最高價以及最低價。

何謂主力成本線

當股價在關鍵位置出現突破、跳空、長紅或是長黑時,且出現大額成交量時,可以視為主力將來的企圖,簡單來說就是商品價格在關鍵位置的平均價格。

何謂市場趨勢

市場的趨勢,就是市場當前正在運行的方向。

何謂量價結構

所謂的量能結構就是指在股票市場的成交量裡面所包含的投資者,在股票市場上大致可以區分為投資機構、官股法人、自營商、基金投資公司、大型投資人以及散戶等。

何謂交易計畫

一個完整的交易計劃內容包含以下幾個重點:交易周期、資金分配、進場時機、停損或是停利點。

何謂交易周期

所謂的交易周期主要區分為日線交易、週線交易、月線交易。三者區別在於交易周期時間的長短。

何謂資金分配

資金分配最重要的是能夠穩妥的降低投資的風險,投資首要的工作就是先求保本再追求獲利。

何謂進場時機

進場時機,通常依據主力成本線量能的表態後,明確出趨勢的方向才開始規劃。

停損設定的重要性

投資首要工作就是嚴格控制風險,規劃進場的同時也要明確地制定停損出場的時機,當局勢並未按照你的交易計劃同步運行時,立即執行,方能長期保持大賺小賠的獲利模式。

停利設定的重要性

本網站中一直強調絕不預設立場讓市場決定一切。我們在進場前所能夠做的就是規劃好自己的交易計劃並且確實執行,真實的商品市場裡面永遠存在著不可預知的未來與風險,沒有人能夠提前預知未來的走勢,順著當下投資市場的實際走勢才是我們最簡單也是最單純的操作方式。

如何調整持倉比例

持倉比例的多寡對於投資報酬率以及投資風險的高低,有著密不可分的關係,所以投資持倉的比例往往也是風險管理中重要的一環。如何去掌握持倉比例,首先可以依照自己內心的感覺去衡量,如果當前這筆投資金額會讓你覺得沉重,請你立刻停止加大持倉的部位。

何謂亞當交易守則

  • 賠錢的部位絕不要加碼「攤平」。
  • 買進或加碼操作時,絕不能不設判斷錯誤時的停損點。
  • 絕不要取消或移動出場點,除非是往你操作的方向移動。
  • 絕不要讓賠小錢演變成重大損失。情況不對立刻出場,保留資金,改日再戰。
  • 一次操作或一天之內絕不虧損超過 10%。
  • 別試著猜頭摸底,讓頭部和底部自己出現。
  • 別站在火車前面。如果大盤出現爆發性走勢,不要和它作對,除非有明顯的證據顯示已經開始轉向了(不是即將或是應該,而是已經轉向)。
  • 保持靈活度。請記住,你可能會錯,亞當理論也可能會錯,世界上任何東西都會偶爾出錯。要記住,亞當理論所討論的,是可能性高的事,不是絕對確定的事。
  • 虧損時,請出場。如果你一直虧損,請認賠出場,暫時遠離市場。讓情緒冷靜下來、讓頭腦恢復理智。
  • 請問問自己,是不是真的想在市場上賺錢,然後仔細聽聽你的答案。有些人的內心想要賠錢,或者只是想玩刺激的東西。請了解自己
