IMO, the right way to look at long-term performance of an investment is on a semi-log chart. (Day or week charts, I prefer linear; anything 3 month or longer, I prefer semi-log.)
Semi-log (where constant percentage changes are constant-sized), it's more than a blip. Linear (where constant dollar changes are constant-sized) charting hides past market moves if the overall bias has been up and exaggerates past market moves if the overall bias has been down. This can lead investors to improperly discount the pain/gain cycle that happened over that time period.
