One dot per month since 1980: how far Bio-Rad Laboratories Inc. stood below its all-time high, and the total return over the following 1, 5 and 10 years.
Read this with survivorship bias in mind: a single asset's history is one surviving sample, so past recoveries here say little about the odds ahead. Monthly windows also overlap heavily (they are not independent samples). Not investment advice.
