📚 Case Studies

1
Great Crash Short Campaign (1929)
Livermore built massive short positions in leading stocks as speculative excess peaked before the October 1929 crash.
✨ Outcome：Profited enormously from the collapse, though later lost much of the fortune through subsequent trading mistakes and overconfidence.
2
Bethlehem Steel Bull Run (1915)
Livermore built an initial stake, then pyramided only as the stock advanced and confirmed strength, adding smaller tranches at higher levels to control risk.
✨ Outcome：Captured a large portion of a powerful wartime advance while limiting exposure if the uptrend failed.
