Google’s stock has been vertical since mid august moving from a $500 stock to $740. This Thursday and Friday saw a sharp change as google sold off $70 to close the week at $663.97. This seems like retracement before a move up, call it profit taking or credit fears the next question is when to go long again. First, standard technical analysis will look for historic points of resistance or gaps to identify the bottom of a retracement. In this case there is almost no way to confirm these critical points because the stock price has blown past most of them. So we throw some Fibonacci retracement lines. Thursday night the stock gaped below the first critical level of 23.6% retracement but closed the week a little more then half way in between there and the 38.2% level. The 38.2% will be a good target for googles stock to rest. If you look to the graph as it moves up there is a small gap just above 650, which is close to our critical fibonacci number. Also my current neuroshell model gave a buy signal after the stock gaped down Thursday night (which i guess means the model isn’t very good, but its rough and not designed to pick day to day changes but trend changes) this is all making me feel pretty good about 650 being the turning place. Still to help give another confirmation I’ve included a graph from Sep. 06 through Jan. 07 where the Fibonacci retracement lines were drawn in to see their relevance. Notice they form strong critical points for valleys and peaks for the next 6 months.Anyways ill be looking to see what google does Monday morning. Its still google and it could very well open up $20 tomorrow and not look back so do your own DD.
