After that we went 135 procent up and still didn't have any drop 27 procent or more. The moral of the story is if you bought any of those 27+ procent drops you are in profit. There were 6 drops in the last 12 months with 27+ procent drops. So on average you had 1 nice chance to buy on every 2 months.
