==Explanation==
A {{w|syllogism}} is a {{w|logic|logical}} argument where two or more propositions lead to a conclusion through {{w|deductive reasoning}}. For example, one of the best-known syllogisms is:
#All men are mortal
#Socrates is a man
#Therefore, Socrates is mortal

In this comic, [[Cueball]] is an engineer who is attempting to make the following syllogism:
#I am good at understanding "numbers" (i.e., mathematics)
#The stock market is made of numbers
#Therefore, I am good at understanding the stock market

Since most engineers are purportedly good at math, proposition 1 seems to be true. It is also loosely true that the {{w|stock market}} is made of numbers, but only in the sense that every system can be given a post-hoc numeric characterization; the dynamics of the stock market are primarily human-driven. In this comic Cueball thinks that his skill at math will help him beat the stock market. Little does he know that the system can be unpredictable, so he ends up losing money as the financial instrument he's invested in loses value. This is due to the financial markets being largely controlled by humans making emotional decisions and not some calculable reason or logic.

Even if the propositions "I am good at understanding numbers" and "The stock market is made of numbers" were true in Cueball's interpretation, Cueball would still be wrong to conclude that "I am good at understanding the stock market": this would be a {{w|fallacy of the undistributed middle}} (with the first premise being more accurately stated as "I'm good at understanding things made of numbers") and a {{w|fallacy of composition}} (with the implicit third premise "if I'm good at understanding the components of a system, then I'm good at understanding the system"). The problem is that proposition 1 seems to say "I am good at understanding all math". However, the "all" is not present, so Cueball may not necessarily understand the math underlying the stock market.

This comic is also related to the 1998 movie {{W|Pi (film)|Pi}} where the main character repeats to himself several times his assumptions that the world is all numbers, and thus he, a great mathematician, should be able to predict the stock market, which is all numbers. He believes that maybe his work on patterns in pi will provide some deeper insight into the patterns in the stock market, a project that drove his mentor crazy and may in fact be making his computer self-aware. 

The title text talks of the scenario where it was Cueball who causes everyone involved in the financial system to lose their money. This could refer to a scenario in which Cueball figures out a way to extract large quantities of money from the stock market, causing a sudden, major decline in everybody else's wealth, or that his involvement has caused literally everyone, including his own, stock market assets to lose their value. This is possible since there is no conservation of value for the stock market. The value of a particular stock is determined by a majority that is willing to trade it at a given price.

The release date of this comic makes it highly likely that it refers at least in part to the {{w|2015 Chinese stock market crash}} which largely affected most other world financial markets, particularly during the week of August 24–28, during which this comic was published.

Two, less likely, interpretations of the title text have been suggested:
#It could also be understood as if everyone makes the fallacy of Cueball and this leads to a much worse global situation - i.e. a stock market crash.
#Alternatively, Cueball could cause a global stock market crash if he is an engineer responsible for vital stock-market-related software and/or hardware. An example of a situation where the action of engineers was implicated in just such a crash is the {{w|2010 Flash Crash}}. High-frequency quantitative trading, which relies more on financial technology engineering than sophisticated financial knowledge, was heavily involved in this particular crash.
