Everything looks good and you have the expected results.
You have a few errors in words (spell check or autocorrect can kill you)
Q3 2017 had the most variation in price as observed by the very long shape.
The underestimate and overestimate of stock prices are significant too.
While we don’t have the data it would be nice to note the estimates were off.
Someone in the company may tighten their projections to determine better estimates later.
Investors would like to have some sort if idea how well the company thinks they are doing.
Overall, well done. Graphs/charts look good and are correct.
