The squeeze could happen today, or next week, or next month, or three months from now. Just buy, hold, and be patient. Ichan has the winning hand, and Ackman's false claims are getting old and tired. Easy money on the long-side, but HLF will be volatile in the short-term.
Sentiment: Strong Buy
Please take into account that if Icahn can get about 10M shares call option OTC for about 5 days, Ackman can do that also. so with current low flow, he can try to keep th eprice down while at the same time acquire large amount of calls in OTC market for a fair amount of low price.
This stock won't do anything until Icahn exercises his options. The volume has completely dried up. Most are holding until then. Hell, if you have a big loss in it, why the hell wouldn't you hold?
