Wendy, a new college graduate with a major in Economics, is interviewing for the Market Analyst position.

Question # 1
Interviewer: Do you know what the acronym 'FAANG' stands for?

Wendy: Yes, it refers to five major stocks: Facebook, Amazon, Apple, Netflix and Google. In fact, I follow all of them very closely.

Question # 2
Interviewer: Okay, now take a look at the FAANG table and give us your interpretation of its overall performance.

Wendy: Obviously, Apple has hugely outperformed the other four components. While Facebook and Google produced fairly good returns, they were nonetheless below the S&P 500's 2019 return of 30%. Unfortunately, Amazon's return was sub-par while Netflix disappointed its investors. 

Question # 3
Interviewer: Why do you think we've added the Coefficient of Variation (COV)?

Wendy: COV is a very common metric used to demonstrate the volatility of asset classes and components. Amazon was the least volatile component while Apple was the most volatile in the FAANG complex.  

Question # 4
Interviewer: By simply glossing over the data series, would you have known that Apple was the most volatile in the complex?

Wendy: Yes, by simply looking at the data series I could have found it out. It has a much wider spread in the series than the rest, resulting in the highest COV and the volatility.


Question # 5
Interviewer: Was that the right use of the COV metric?

Wendy: It's perfectly fine in an interview setting. If I were compiling a report for a client, I would go back to the daily closing data, at least the weekly closing.

Question # 6
Interviewer: Okay, now switch to the Apple vs. Facebook chart and compare and contrast their performances. 

Wendy: They moved more or less in tandem during the first half of the year. Since then they produced significantly different performances. While Apple continued on a linear  growth path, Facebook moved sideways, remaining mostly range bound.

Question # 7
Interviewer: In terms of the market behavior, do you notice any similarity or dissimilarity between Amazon and Google?

Wendy: Yes, very dissimilar behavior. During the first half of the year, Amazon produced a nice run-up, while Google continued to decline. They however reversed courses in the second half.

Question # 8
Interviewer: Now let's move on to the Amazon chart. What is the point of overlaying the 2-month moving average trendline?

Wendy: To introduce a level of smoothing. It smooths out the noises that are inherent in month-over-month data series. For instance, the moving average trendline here is proving that the April and May data points are somewhat aberrations.   

Questions # 9
Interviewer: How would you graph all five components into one graph?

Wendy: By showing the month-over-month +/- growth rates, so they are apples-to-apples.
