Nasdaq to Boost Rebate On PSX

Nasdaq OMX Group plans to goose its rebate for traders providing liquidity to its Price/Size Exchange, or PSX. Along with that, however, comes a price increase for takers of liquidity.

The moves comes as volume on Nasdaq OMX PSX languishes at about 1 percent of total volume. The exchange was launched last October.

Effective September 1, Nasdaq will increase both its base rebate and its best rebate by two cents per hundred shares. That means the base rebate will rise from 22 cents per hundred shares to 24 cents. The best rebate will rise from 24 cents to 26 cents.

To qualify for the higher rebate traders must post at least 2,000 shares per order. The exchange was established to encourage trading in size.

For takers, the fee will rise from 25 cents to 27 cents.
