Where were you on March 17, 1998? Microsoft’s stock was at $18.08 when the closing bell rang on that date. That’s the last time it was lower than it is today. Shares closed the trading day today — adjusted for splits, so the numbers are comparable — at $18.29, down $1.33, 6.8 percent on the day.
Note: This post originally (and wrongly) indicated that the last time Microsoft shares were this low was Jan. 30, 1998.
