Why was Yahoo shoting up over 3% today

Yahoo shares (YHOO) rose 3.46% to $22.70 today, after Barclays analyst Anthony DiClemente raised his rating on the company’s stock to overweight, or the equivalent of buy, from equal weight. DiClemente also raised his price target on Yahoo to $26 a share from $22. In a research note, DiClemente said the value of Yahoo’s minority stakes in Alibaba Group and Yahoo Japan are “not fully reflected” in the company’s current share price.

I'm just wondering what this guy and other supposed more "knowledgeable" analysts were doing when I talked about YHOO's value a year ago and again a few months ago. As you can see, the Alibaba and J-Yahoo were exactly the major values I was talking about why Yahoo was so valuable when it was about $15. Looks like these guys just woke up now. Anyway, I'm certainly happy with what YHOO is doing for me. Below is the status of my 2 holdings for YHOO:
