"because it is obvious this stock is in a down trend?"
Congratulations... it's been in a downtrend since mid 2011, some 2 years ago.
"Time to buy"
Depends on your strategy :)
If you're up for it, around Aug next year AGO should be reporting 40cents per share earnings... if all goes to plan, I'm expecting earnings of $2+ per share per year from 2017 onwards... if not much goes to plan then I'm still expecting about 40cents earnings into the future.
If you're looking to trade for a swing, as theRabbit suggests, there's others about. If you're playing the double bottom, the common strategy is wait for the stock to get to the neckline, sideways consolidation, break upwards, BUY BUY BUY. Just look at ILU gooooooo....
