FYI: It might seem like it at times, but investing is not a solitary activity. The market is a dynamic living entity driven by traders buying and selling assets either as individuals or as institutions. Knowing what other traders think of a stock can help you find undervalued companies before they become too expensive or let you know when to sell and take profits before the stock begins to fall.
