First, I've not just been in the markets for five or ten years so might not be the smartest but do have experience and this is like others; just opinions with some facts.
Fact: Coal has been out of favor three years. Opinion is I think turnaround starts November and ACI has most to gain from current price as in going to over $40 long term.
Facts: Unlike most companies at this time in negative (XYZ), ACI is positive yet needs improvement; Operating Cash Flow (ttm): 321.11M
Levered Free Cash Flow (ttm): 91.68M
Most stocks trade at multiples higher than book value but all stocks will hit book value at some point and to find value, you want low PEG, good P/E and many things but you want positive numbers above and a stock that if it has debt, is LONG TERM debt so no going concern, trading below book and if lucky below cash per share! We have that with ACI-Book Value Per Share (mrq): 13.11 & Total Cash Per Share (mrq): 4.61 W/ Current price of $3.98 is silly low based on panic and subjective material not objective material.
ANR is a good buy too and so is BTU with BTU being in a better financial condition as someone else said but the value is what shareholders want and that is found in which goes up the most percentage points in recovery and only ACI can go up the most imo so I select ACI out of the coal stocks since coal is not going away and global warming was a fraud anyway imo
ACI has hit a bottom so it looks, is oversold and time to buy is Monday imo.
