January 1988 -- Three months after Black Monday, October 19, when the the Dow Jones industrial average plunged 22.61 percent, Institutional Investor wrote, "We have yet to come to grips with the excesses and weaknesses the market crash laid bare." Some of the very excesses and weaknesses laid out in the January cover story, "After the Fall," reverberate today.
