Iomega (the Zip Drive people) dropped to $1.67 in the mid-late '90's. I noticed it but did nothing. They went on to split several times, 2 for 1, 3 for 2, etc., and finally fell into the toilet at over 30 bucks per share.
Had I put 20K into them at the bottom, made arrangements to sell off without perturbing the market, I would be typing this from a residency in the Cayman Islands.
Not that I'd be posting on TBD in the first place, if that happened...
