What is Fibonacci values?
Usually when a stock is up-trending or down-trending the price does not go up or down in a straight line. In an uptrend the price may go up over a couple of days then it could go down the next day or two, but the general direction would be up over the medium term. The opposite for a downtrend. So if the stock has been generally going up over the last few weeks, it may take a breather for a week or two before prices continue up again. This breather is called a retracement in the uptrend. The Fibonacci levels are possible amounts by which the price might retract before it continues on its way up again. By the way 50% is not actually a Fibonacci Retracement level but it is a common retracement level which is usually used in combination with the Fibonacci Retracement levels.
