Review: Lessons 12–17 on one chart
Why this chart
Amgen (AMGN) packs the whole last week of lessons into one five-month stretch: a trendline that held, a range you should have sat out, a breakout on volume, an inside day right at the high, and a moving-average stack that broke in September and repaired itself in October. Try the quiz first, using only the chart. Then read the answers.
Quiz
- Q1 (weekly first, Lesson 14). Before looking at the daily chart, what does the weekly panel tell you about the big trend?
- Q2 (trendlines, Lesson 12). Which two points anchor the purple trendline, and is it still valid?
- Q3 (ranges, Lesson 13). From Sep 22 to Oct 13, should you have traded it or sat out? What ended the range?
- Q4 (EMA vs SMA, Lesson 16). After the Sep 8 gap down, which 21-day line turned back up first, and by how much earlier?
- Q5 (inside days and the stack, Lessons 15 and 17). What is Oct 23 telling you, and how does the stack read right now?
Answers
- A1. The weekly chart shows an uptrend. The spring low was $320.52 in the week ending May 8. Every pullback since then has bottomed higher, and the September dip, the sharpest one, stopped at $374.46, far above that spring base. So you read the daily chart expecting the uptrend to continue, not end.
- A2. It connects the Jun 2 low ($322.30) and the Sep 16 low ($374.46). No daily close has been below it since Jun 2, so it’s still valid. On Oct 23 it sits near $393.75, about $45 under price. That’s too far away to use as a stop, but it’s still the line that defines the trend.
- A3. You should have sat out. For three weeks price swung between $396.01 (Oct 6) and $426.59 (Sep 30), and the 9 EMA, 21 EMA and 50 SMA stayed within $1–8 of each other the whole time. Lines tangled like that mean there is no trend to trade. The range ended on Oct 15, when AMGN gapped up and closed at $434.03, above the box, on about 1.7 times its 50-day average volume.
- A4. The 21 EMA bottomed on Sep 21 (about $400.48) and turned up. The 21 SMA didn’t bottom until Oct 6 ($397.74), 11 sessions later. The EMA weighs recent days more heavily, so it caught the recovery sooner. The SMA was slower but steadier: it never gave a false turn in the middle of the range.
- A5. Oct 23 was an inside day: its range ($439.07–444.59) sat entirely inside Oct 22’s range ($437.19–450.98), and Oct 22 was the high of this whole chart. It’s a pause after a new high, not a signal on its own. A move above $444.59 or below $439.07 shows which way the pause breaks. The stack is fully bullish again: the close ($439.26) is above the 9 EMA ($433.26), which is above the 21 EMA ($423.61), the 50 SMA ($417.26) and the 200 SMA ($371.61). All four are rising, and the 200 SMA rose $9.48 over the last 20 sessions.
What to notice
- The order matters: weekly trend, then structure (the trendline and the range), then the moving averages, then that day’s candle. Each step narrows the question.
- The Sep 8 gap (close $393.17, from $437.23 the session before, on about 6.8 million shares) broke the short lines but not the trendline or the weekly uptrend. The fast lines flip first; the structure tells you whether the flip matters.
- Patience paid. A trader who waited for a close outside the box got one clear move in place of three weeks of whipsaw.
Common mistake
Reading one tool in isolation. If you looked only at the 9 and 21 EMAs on Sep 9, you’d have called the trend broken. The weekly chart and the trendline said it was a pullback. When your tools disagree, the slower ones, read first, get the deciding vote.
Try it
Pick a stock you follow and go through the same five questions in order: the weekly trend, the trendline, range or trend, which 21-day line turned first, and the latest candle plus the stack. Write one line for each. If you can’t answer one, that’s the lesson to reread.
