❓ Why It Matters
A single large drawdown can erase years of progress. Risk control is not timidity; it is the operating system that keeps compounding alive.

Oversized positions without an exit plan
Using leverage to compensate for uncertainty

2
RJR Nabisco Post-LBO Debt (1988)
Following KKR’s leveraged buyout of RJR Nabisco, many investors dumped the overlevered company’s bonds amid fears of default and recession.
