June 2007 witnessed the failure of a broker-dealer that specialized in trading collateralized-mortgage obligations ("CMOs") on margin. See Bruce Kelly, "Brookstreet Clients, Counting Losses, Ponder Arbitrations," Investment News, July 9, 2007.
Published reports indicate that Brookstreet sold clients volatile species of CMOs known as "interest only strips" and "inverse floaters." These CMOs behave much like the margined investments. In comparison to less volatile types of CMOs, these instruments deliver compounded returns -- and compounded losses.
A brokerage firm selling inverse floating CMOs on margin would compound that risk even more. That's what many believe happened at Brookstreet. Reports indicate that Brookstreet sold these investments, on margin, to elderly and/or unsophisticated investors. When the CMOs declined in value, these elderly investors suffered not only major losses, but became indebted on their margin interest. That's generally not the kind of thing firms should be selling to elderly or unsophisticated investors.
Because many of Brookstreet's brokers operated out of their homes, it's doubtful that Brookstreet brokers did a lot of business with large institutional purchasers for whom these high-risk securities are best suited.
Games may also have been played with the valuation of Brookstreet's CMOs that hurt investors even more by overvaluing the CMOs at the time Brookstreet sold the investments, but undervaluing the CMOs in making margin calls. This would be like a homebuilder loaning money based on an overvalued house and thereby creating a larger monthly note. But when the borrower defaults, the homebuilder/lender grossly undervalues the house at foreclosure, leaving the borrower with jumbo liability but shrunken collateral.
According to a major defense-oriented law firm, that's may have happened at Brookstreet. In July, Holland & Hart posted an extraordinary blog post criticizing not only Brookstreet, but also its clearing firm, NFS -- owned by Fidelity -- for possible manipulation of the values of the CMOs that Brookstreet sold to retail investors. See "Brookstreet Securities Collapse: Where Were the Regulators?"
That sort of conduct could expand the scope investor recovery beyond the failing Brookstreet to the well-heeled NFS/Fidelity.
