So long as you don't wait forever. The market bottom of any exchange or stock is $0.00. The market, will likely never actually "bottom out". Look into DCA Dollar Cost Averaging. I personally, and professionally, manage DCA strategies with applying additional infusions during obvious lows (example: markets are down 10% in a given period). The bottom of a cycle can undulate "sideways" a bit over a period of weeks, months, years, decades with few discernible entry or exit points. Sometimes after an "event" occurs, the market/stock jumps XX% and opportunities may not occur again in the near future (goes sideways at new level). I note sideways markets/stocks and calculate the risk/reward if I deem it an opportune time. In most markets stocks don't go sideways forever.
