I get a good laugh when I see a downgrade, and in the same report the price target raised. How can that be?!?
Anyway, the Citi downgrade caused AGO to decline pretty nicely in the AM, but I think that decline was due to ’shoot first-ask questions later’ attitude. The analyst, despite the downgrade, increased the price target to 28, and admits to the bullishness toward AGO’s business. (article)
I pretty much agree with the article, except for the downgrade on such a bullish scenario. But I think the Citi analyst was looking at a chart when they called it a hold. At the moment AGO will be range bound, but this is the time to buy it, not when it breaks from the pattern.

AGO should be bought now, and when it reaches its upper limit of the trent line (around 26), sell the 25 April Calls or buy the 25 April puts. As AGO consolidates back down, close out the protective option positions. (I have been selling calls everytime mid 25 was seen, then closing the position when 23/high 22 was seen after the call sale. I also had the intention of buying puts when the upper trend limit was achieved.)
