Summary

  • Post warns that the S&P 500’s extreme concentration (34% in 10 AI-related stocks) mirrors Korea’s bubble, where a 10% drop in one day triggered a massive margin cascade.
  • Author is bearish and sitting on cash, questioning whether a small AI earnings miss could ignite a similar crash, but acknowledges the counterargument that institutions absorb dips.
  • Quality: Opinion/speculation with a historical analogy; lacks hard data or rigorous analysis, but raises a valid structural risk.
