Investopedia explains 52-Week High/Low
Many investors see the 52-week high or low as an important indicator. For example, a value investor may view a stock trading at a 52-week low as an initial indication of a possible value play (a stock sitting at a price below its intrinsic value). An astute value investor will have to conduct a lot more analysis to come to this conclusion, but the fact that the stock is trading at its 52-week low can be a potential starting point.
