Analys över hur High Frequency Trading påverkar Orderbokens Likviditet (Swedish)
Abstract [sv]

Arbetet syftar till att få en djupare förståelse kring High Frequency Trading (HFT) och hur detta påverkar marknadslikviditeten i orderböcker. HFT utgör en majoritet av handelsflödet på finansiella marknader. Genom att utvärdera data från de största europeiska aktierna under 2023 gör denna studie en analys över effekten av HFT på orderböckerna och dess likviditet. Mer specifikt analyserar arbetet hur orderbokens spread och price impact påverkas av mängden HFT. Studiens resultat visar att en högre närvaro av HFT minskar price impact i orderboken och marginellt minskar spreaden och därmed har en överlag positiv påverkan på orderbokens likviditet. Denna forskning bidrar inte bara till en ökad förståelse kring det akademiska ämnet om HFT, utan ger också insikter för olika marknadsdeltagare och regleringsmyndigheter. Dessutom utforskar studien den unika strukturen hos den fragmenterade europeiska aktiemarknaden och hur konkurrensen mellan handelsplatser kan påverka likviditeten. Denna analys av HFT och dess påverkan på orderbokens likviditet ger värdefulla insikter för framtida studier och regelverk.

Abstract [en]

This report aims to get a deeper understanding on how High Frequency Trading (HFT) impacts market liquidity. HFT is a significant part of modern financial markets, accounting for a large share of trading volume on stock exchanges. By evaluating data from the largest European stocks in 2023, this study assesses the impact HFT has on the lit continuous orderbook and its liquidity. More specifically, the study analyses how price impact and spread of a security are impacted by the amount of HFTs. The findings indicate that higher HFT presence reduces price impact, marginally narrows the spread, and thus enhances the orderbook liquidity. This research not only contributes to the academic topic around HFT, but also offers insights for market participants and regulators. Additionally, the study explores the unique structure of the fragmented European stock market and how venue competition might influence liquidity. This analysis on HFT impact on market liquidity provides valuable insights for future studies and regulatory frameworks.
