LTCM’s trades were largely familiar plays already identified by academics

Evidence

Some of LTCM’s trades were well known to market insiders before LTCM became involved. The Royal Dutch/Shell trade, for example, was the “classic European arbitrage trade” (Wenman interview), and the relationship between Royal Dutch and Shell shares had even been discussed in the academic literature before LTCM was founded (Rosenthal and Young 1990). News or speculation about other LTCM trades circulated freely. “I can’t believe how many times I was told to do a trade because the boys at Long-Term deemed it a winner,” says the hedge-fund manager James Cramer (2002, p. 179). — Donald MacKenzie, An Engine, Not a Camera, 1028

Categorization

• XREF: The Royal Dutch/Shell twin-shares trade is a famous anomaly study, and the claim that LTCM’s edge lay mostly in execution/leverage rather than novel positions undercuts the mystique narrative — echoes of efficient-markets critique and of Frazzini/Pedersen’s later work on the same trade. — connects to: Other traders imitated LTCM’s successful arbitrage models and strategy — Donald MacKenzie, An Engine, Not a Camera: How Financial…, 155; Practitioners knew market anomalies before academics documented them — Donald MacKenzie, An Engine, Not a Camera: How Financial…, 425; LTCM’s disclosed strategy led rivals to take similar arbitrage positions — Donald MacKenzie, An Engine, Not a Camera: How Financial…, 1027 (+1 more)
• QUESTION: If LTCM’s trades were largely known already, how much of the fund’s edge was genuinely alpha versus leverage-enhanced exposure to a well-documented anomaly? Worth chasing.
