![]() I think $TSLA is a good example from 2015. ![]() There is no hard and fast rule to what exactly constitutes “flat”, but a little common sense in this case goes a long way. In a lot of cases, I’ll punch up a ticker symbol and I will see price right near a flat 200 day moving average. But even if you have a shorter or even a longer-term time horizon than I do, I think this one simple lesson can help (This can also be implemented in weekly timeframes for longer-term investors using a 200 week simple moving average). I look out weeks and months so the 200 day helps me with that. This is enough to data to get an idea of the direction of the intermediate-term trend, which is the timeframe I personally choose to live in. So you’re essentially looking at the average daily closing price from the past 3 quarters. 200 trading days represents about 9 months of data. We use this moving average primarily to help identify the trend, or in some cases, a lack thereof. Is price above an upward sloping 200 day? Or is price below a downward sloping 200 day? That’s much more valuable information. What we really want to observe is the slope of this smoothing mechanism. It makes for a nice soundbite and fills airtime, but for a market participant, this is the equivalent of them telling you that $XYZ just changed it’s ticker to $STFU. So when you hear, “$XYZ just crossed below its 200 day moving average”, that doesn’t mean anything at all on its own. This is an invisible line as far as supply and demand is concerned. With each day comes a new plot though time, which is why it appears as though it is moving.Ĭontrary to popular belief, there is no support or resistance history at this average. Each day, the trading session from 200 days ago gets removed from the calculation and the new day which just ended gets added. Usually the 200 day is referring to the 200 Day Simple Moving Average, which calculates the average closing price over the prior 200 trading days. The 200 day moving average is one that is mentioned a ton throughout the financial media and twitterspheres of the world, but is often misinterpreted for whatever the reason. I want to reiterate “supplement”, because price is the most important indicator we have, it’s the only one that we can actually trust, and the rest are there simply to add confirmation or help dissuade us away from our thesis. ![]() Long-time readers know that I only use a handful of tools as a supplement to price action. Today I want to bring up something that I discuss often, but I’m not sure that I ever explained clearly in a blog post.
