TCS & WIPRO - correlation horribly broken in last 10 days!

I have to admit that this correlation is broken for a good reason. Wipro gave bad results and TCS gave good results. But do results really matter more in trading or patterns & technicals?


TCS & Wipro daily chart for last 3 months. They were pretty decently correlated but in last 10 days they have diverged almost 25%. 
So a pair trade possible with short of TCS and long WIPRO. Just need to adjust for lotsizes because TCS lotsize is 250 and Wipro is 833

Although 1 day of data is missing here the divergence is very clear on a 30-min, 10 day chart. Even if the results of TCS are great and Wipro is bad - there's got to be some profit booking in both - I mean shorts will book profits and Wipro might rise and TCS might fall when longs book out.
