2101: Technical Analysis
| This explanation may be incomplete or incorrect: Comic is still undergoing TECHNICAL ANALYSIS (this is just the prologue). Do NOT delete this tag too soon.|

The theoretical value of a stock is the sum of all its future earnings, with earnings in the future discounted appropriately to account for the time value of money. Because these earnings are never fully predictable, traders may have different ideas about the true value of a stock, and buy the stock if they believe the currently offered prices are particularly low, or sell it when the prices are high.
Technical analysis, however, does not even attempt to understand the earnings of the stock, instead focusing on the shapes and patterns that result from traders making their moves. While there is a human behavioral component to stock trading, it is not clear that one can extract much information from the shapes of stock charts. To the extent it does work, a substantial part of its success may be simply an artifact of the herd behavior of traders who engage in technical analysis, a zero-sum game.
The comic displays a stock price chart, annotated with labels which purport to be technical analysis. These labels are nonsense from the perspective of technical analysis, but do accurately describe the graph itself: "allegro" (a musical term used to set the tempo at the beginning of a score), "prologue" (an introductory section of a play, book, or similar), "lumbar support" (the thing in a chair shaped to better support your back), "bathtub" (possibly a reference to the so-called "Bathtub curve"), "uptalk" (a speech pattern). One label celebrates that "these two points define a line! Promising signal." (In Euclidian geometry, any two points define a line.)
|Allegro||Tempo notation in music: played quickly and brightly - a series of very small changes in this region of the graph might suggest notes played quickly|
|Decline||Describes a negative trend|
|Doldrums||A stagnant section of the graph with little movement|
|Spline||A spline is a mathematical means of generating a smooth curve, referring to the smoothed curve shown here|
|Prologue||A prologue is an introduction to a book or other work; this presumably refers to the initial period of minimal growth which is moving toward a much more active period|
|Lumbar Support||A cushion or other device that provides support to the lower part of the spine, a play on the preceding spline|
|Renewal||Strong upward trend; also might suggest the growth of green bars, like greening up in the spring|
|Hark! The cliffs!||A long bar suggesting a steep cliff|
|Declination||Another term for a downward trend|
|Inflection||A point at which the slope of a graph changes|
|Uptalk||A pattern of speech in which each sentence ends with rising inflection? like a question? A play on "uptick", and also on the second meaning of "inflection"|
|Bathtub||possibly a reference to the so-called "Bathtub curve"|
|These two points define a line! Promising signal.||In Euclidian geometry, any two points define a line; also looks somewhat like a communication line between two towers. It is tempting when looking at market charts to draw imaginary lines that connect the extrema and hope it means something about the future.|
|Could be an omen|
|Red + Green = Christmas|
|Likely to continue forever||This is the opinion held by everyone who buys at an all time high. It's been rising so much, surely it's the best time to buy! We could make millions! Such times are generally followed by a sharp downturn resulting in significant losses, as can be seen historically farther back on the chart. Cryptocurrency communities have significant members who call themselves "hodlers" -- these people always trust that the price will eventually go up even higher, because it has recovered so many times in the past.|
The mouseover text is a quote from James Tobin (from his 1984 paper On the efficiency of the financial system) that raises a question of very talented people building systems to make themselves a lot of money without actually accomplishing anything worth money. The quote was about the stock market and high speed traders in particular. It comments on the 'financialization' of the economy, where activities like speculation and abstracted financial products have become an increasingly large part of the economy, as opposed to investment in productive industry.
Interestingly, this comic appeared the day after Oxfam reported that the world's 2,200 billionaires had added 12% to their wealth in 2018, while the 3.8 billion people comprising the poorest half of the world's population had lost 11%. Perhaps this prompted what appears to be Randall's jab at those whose business is merely making money.

- [A series of red and green box-and-whisker plots form a line that starts in the bottom left corner of the image and wiggles up to the top right corner, with a series of peaks and troughs that resemble a typical stock market diagram. The diagram is annotated with lines, arrows and text.]
- [Title in top left corner]
- The basics of technical analysis
- [A roughly horizontal section with mostly green boxes:]
- [A horizontal bracket encompasses the next three sections]
- [Slope becomes slightly negative. Mostly red boxes, bordered with a black line above and below:]
- [A roughly horizontal section with mostly green boxes, bordered with a black line above and below:]
- [Line curves upwards with mostly green boxes, with a dashed black line below:]
- [Three green boxes at minor peaks in the line are circled and indicated with arrows:]
- [A section with slight positive slope and a mixture of red and green boxes, with a solid black line below:]
- Lumbar support
- [Slope increases. All green boxes, with a black line through the centre:]
- [A sharp upwards incline, with two large green boxes:]
- Hark! The cliffs!
- [Two black dots and a dashed black line connect two major peaks:]
- These two points define a line! Promising signal
- [Inside trough between two major peaks is a roughly drawn black triangle:]
- [Slope becomes negative, mostly red boxes with a black line through the centre:]
- [At the lowest point of the trough:]
- [Slope becomes positive, mostly green boxes with a black line through the centre:]
- [Slight negative slope, with large error bars. Mixture of red and green boxes. One red box is marked with an arrow:]
- [Negative slope, all red boxes. Gap between two central boxes is circled:]
- [Line rises then falls. Mixture of red and green boxes with non-parallel dashed black lines above and below:]
- If I add some lines here I can convince myself I'm doing something more than just seeing patterns in a graph of a random walk.
- [Positive slope, all green boxes with a black line through the centre:]
- [One error bar on a green box is circled:]
- Could be an omen?
- [Arrow indicating peak:]
- Red + Green = Christmas!
- [Positive slope, all green boxes with a wiggly black arrow through the centre. A separate arrow points off the edge of the page:]
