Market Making

The leading market maker in UK equities

Winterflood Securities is the leading market maker in UK equities, making markets in nearly all London Stock Exchange listed securities with more UK stocks covered than any other firm.*

The company is a leading liquidity provider or market maker in UK and EU equities offering clients:

  • Certainty of execution
  • Trade in single fills
  • Price improvement facility
  • Enabling trading when clients otherwise would not be able
  • Efficient settlement

We employ over 70 market makers, each with significant expertise in working client orders, helping to reduce the market impact of larger orders and achieving a high quality of execution. Our traders are independent without internal conflicts allowing them to make competitive risk prices when required. Clients may connect to two of the UK’s leading e-trading platforms, both of which are proprietary and state of the art, allowing high speed low latency straight through execution of orders.

European and North American Securities

In equities we provide coverage in nearly all UK securities and the main European and North American markets. As an innovative and forward thinking company we were early adopters of the exchange traded products (ETPs) market and subsequently now have one of the largest footprints in the sector. We also access the various dark pools of liquidity and are one of the primary houses trading with the European multilateral trading facilities (MTFs).

Fixed Income Securities

Since 1994 we have been trading in the fixed income market. The Fixed Income team makes markets in a wide range of Sterling fixed income products which include all UK Government Gilts, sterling bonds, preference shares, PIBS and bond related exchange traded funds.

Listed Products

To assist our retail broking clients in offering an efficient market making service online we have enhanced our electronic trading portal Winner to offer execution in securities where we don’t make markets. In partnership with two investment banks, The Royal Bank of Scotland and Société Générale, we offer the ability to trade in their listed products though our extensive network of connections thereby providing more diverse investment strategies to investors.
