They help me figure out: How aggressive I want to be My mix of day and swing trades Which stocks and sectors I want to be long or short Just how strong the current market trend is What news matters, and what doesn&#8217;t I rate moving averages above news, economic data, earnings, and just about any indicator you can think of. If I was a starting trader looking to build my net worth, moving averages would be my #1 focus. And through a series of new case studies, you will learn: What a moving average is How moving averages are calculated The specific moving averages I use, and how I use them to detect strength and weakness The biggest myth of moving averages Editor&#8217;s Notes: If you want even more moving average case studies, please check out The Ultimate Guide to Moving Averages. Positions Disclosure: at the time of writing, Scott was long MBIO, SPY puts; was short SPY calls, SPY puts What Is a Moving Average? And How Are They Calculated Let&#8217;s talk about how moving averages are calculated. A moving average is a stock&#8217;s average price over a specific time period. A daily moving average is the average of a stock&#8217;s daily closing prices over a specified number of days. (a weekly moving average would be the average of a stock&#8217;s weekly closing prices over a specified number of weeks) We&#8217;ll focus on the daily time frame in this guide. For example, the 50 day moving average is a stock&#8217;s average closing price for the last 50 days. Every day, the newest closing price in the moving average replaces the oldest, which is why we call it &#8216;moving&#8217; &#8212; a moving average change every day. Here&#8217;s a simple chart of Apple (AAPL) with its 50 day moving average. The Biggest Myth About Moving Averages People often say &#8220;moving averages don&#8217;t work&#8221; or &#8220;everyone sees the same moving averages, so they have no value&#8221; But here&#8217;s the reality: most serious technical analysts understand that a moving average is not the same as a trading strategy or even a signal. I don&#8217;t buy and sell purely because of a moving average. But moving averages do help me understand the trend which contributes to my overall decision-making process. That&#8217;s why they&#8217;re so valuable to me. Simple vs. Exponential Moving Averages There are 2 types of moving averages &#8212; simple and exponential. They are calculated in slightly different ways. A simple moving average is exactly what it sounds like &#8212; a simple average of the stock price. (the closing stock price, specifically) An exponential moving average gives extra weight to recent prices, so it does a better job of measuring the near-term trend. Here&#8217;s Advanced Micro Devices\u00a0(AMD) with its 50 day simple (blue) and exponential (pink) moving averages. They&#8217;re pretty close, but the exponential (pink) is closer to the current price. The Moving Averages I Use Technicians and traders have tended to focus on the 10, 20, 50, and 200 day simple moving averages, which you can think of as follows: 10 day simple moving average:\u00a0very short-term trend 20 day simple moving average: short-term trend 50 day simple moving average: intermediate trend 200 day simple moving average: long-term trend I use a slightly different set of moving averages in my own trading, and in Redler All-Access: 8 day exponential moving average:\u00a0very short-term trend 21 day exponential\u00a0moving average:\u00a0short term trend 50 day exponential\u00a0moving average:\u00a0intermediate trend 200 exponential\u00a0moving average: long-term trend (I matched the colors here on the charts below.) I use exponential moving averages because they are more sensitive to the recent action, which gives me a better read on the near-term trend. Going forward in this article, all moving averages are exponential. Is There a Difference Between an 8 and 10 Day Moving Average? You may be asking &#8220;why the 8 day moving average? Why not the 10 day?&#8221; Most of the time, they&#8217;ll be very close together, as shown in this Amazon (AMZN) chart: But here&#8217;s what most people miss about moving averages: It&#8217;s not the exact moving averages you use that counts. It&#8217;s how well you use those moving averages to find opportunities, avoid trouble, and manage risk. I pay most attention to the 8 and 21 day exponential moving averages. I stick with those because my brain is trained to judge the action based on those time frames. If I was using, say, the 10 and 20 day simple moving averages, I&#8217;d probably end up with the same results &#8212; I&#8217;d just get there in a slightly different way. The Power of the 8 &#038; 21 Day Exponential Moving Averages Traders often ask me why I talk about the 8 &#038; 21 day exponential moving averages so much. Whether you see me on Fox Business, CNBC, Twitter, or the Virtual Trading Floor\u00ae, odds are you&#8217;ll hear me me talking about them. Stocks that are in uptrends find support at the 8\/21\/50day. Stocks in downtrends get rejected at them on Bounces. Below the 200day is real selling. Rules to live by \u2014 Scott Redler (@RedDogT3) November 14, 2018 [tcb-script async=&#8221;&#8221; src=&#8221;https:\/\/platform.twitter.com\/widgets.js&#8221; charset=&#8221;utf-8&#8243;][\/tcb-script] It&#8217;s because these moving averages are the most accurate short-term road map I&#8217;ve found. And I value moving average more than any other analysis I see out there. 8 &#038; 21 Day Moving Average Case Study I: The Energy Sector From the 2020 pandemic low to the time I&#8217;m writing this (October 2022), the energy sector dominated the market. Here is a chart of the VanEck Oil Services ETF (OIH) from December 2021 to March 2022 with the 8 and 21 day exponential moving averages. As you can see, the moving averages are sloping up. What were they telling us? They were telling us the trend was strong. As you can see, OIH just trended up along the moving averages, with occasional breaks that were quickly reclaimed. This is a classic powerful uptrend.
