Estimate how long you need to hold Ironwood Pharmaceuticals to reach your target.
Hmm, we can't give any reliable projection for Ironwood Pharmaceuticals's growth rate. The company either has too few years of historical data for us to examine, or it's in the habit of losing money.
None of this means it's a bad stock. Maybe it's new and growing quickly, or maybe it's turning things around. We can't say anything sensible about it, so we won't say it's obviously undervalued right now. Proceed at your own risk!
