What to Watch

  • STRR follow-up filings: whether buy/sell pairing continues or resolves into one-way accumulation.
  • Eberwein code mix: persistent paired P/S lines suggest rotation; one-way S clusters would change the signal.
  • Holder persistence at Dimensional and Vanguard: broad institutional retention would reduce the bearish weight of mixed insider flows.
