Shotry, you asked for a view on this. Timely too I think since it looks pretty good to me. Here's the daily chart:

It's closed very close to the highest price for years (326.3p) and the RSI looks strong. I'd wait for a close above 326.3 and then enter long on a backtest of that level (assuming it does that).
There is a daily P&F target of 357 but the weekly has active targets at 381 and 387 which seem more realistic as the next resistance is 393.75p from 29 Jan 2001 - yes, that far back! A new high above 326.3 activates a P&F target of 474p on the same weekly chart.
The lagging line broke through the daily cloud on 30/11/12 and made a perfect backtest 4 days later so now both it and price are above the cloud which is also bullish.
Short term uptrend support was at 297.85p today and the main uptrend support from the 2002 low was at 264.21p.
I suppose the only concern is the Dow being so close to its all time high but we don't know whether it'll go through it or not or whether it would even make a difference to this stock anyway.
