If you are interested in forward planning your buy back of CBA from a charting point of view the use of Fibonacci numbers highlights target areas.

If we take the top of $145.24 & the starting point as $109.94 we get the total move to be $35.30.

23.6% correction = $136.91 (we have already gone lower)
38.2% correction = $131.76
50% correction = $127.59
61.8% correction = $123.42
76.4% correction = $118.27

61.8% is a very common correction percentage & it fits in with my original preferred correction target of between $120 & $125.

At $123.42 the yield is 3.7676%, not all that flash but if you wait for $118.27 you may miss out. Buying any earlier than $123.42 means that your cash is locked away in a stock with a poor yield.
