RE:Use PEG Ratio as Best Gauge to show How UndervaluedJIN,
Great stat but I believe you mixed up USD and CAD in your calculation. I would also use the $0.76 EPS figure from 2017 as it was the number for continuing operations (the $0.64 included a loss from discontinued operations).
So your EPS estimate for 2018 of $1.17 is in USD but you use the CAD stock price. You should be using the USD stock price, which today is $21.14.
Thus, $1.17 USD EPS to $21.14 gives a PE of 18.
The YoY earnings growth is 55.2% ($1.18 / $0.76)
The PEG ratio is 0.32 (18 / 55.2). These are incredible numbers. The most important item is this is going to keep going big time.
2016 EPS $0.35
2017 EPS $0.76
2018 EPS ~$1.18 (PE 18)
2019 EPS ~$ 1.83 (assuming they keep up this type of growth - 2019 PE would be 11.5)
This is incredible.
