We can almost hear that ominous “Jaws” theme music in the background and can see that huge dorsal fin as it slices threateningly through the water – knowing full well that the real terror is hidden beneath the water’s surface.

But this time around, it’s not a “Great White” that’s sparking our fears; it’s a well-capitalized and broadly based series of secret stock exchanges known as “Dark Pools of Liquidity,” “Dark Liquidity,” or just “Dark Pools.”

But that’s not the case with Dark Pools.

Trading huge quantities of stock on traditional exchanges has become ever more challenging, costly, and potentially disruptive. And if other players see your moves, they can disrupt your trades. That’s led to the emergence in recent years of alternative trading systems known as dark pools. And their growth could have significant implications for big stock exchanges-and individual investors.
