leave chips on the table
v. phr.— «What you find is that the passive hedgers and other nonprofit participants leave “chips on the table” in the currency market, that speculators, in essence, are able to take advantage of. The nonprofit participants are willing to take the other side when the speculators see an opportunity.» —“Douglas Stark State Street Global Advisors” Wall Street Transcript Nov. 8, 1993.
