The annual Russell US Indexes Reconstitution in late June is a major event for investors and traders. FTSE Russell updates both market capitalization and investment style definitions, which means the impact cuts across companies of all sizes. This can result in large liquidity demand as index funds need to rebalance their portfolios and active investors seek to leverage the unusual liquidity in hard-to-trade securities.
The 2020 reconstitution on June 26 was expected to be one of the largest on record, and it did not disappoint. The NYSE Closing Auction had its second-largest trade ever by shares, executing 2.3 billion shares valued at nearly $70 billion. Nasdaq traded roughly 1.6 billion shares with a notional value of almost $57 billion.
NYSE Designated Market Makers (DMMs) may facilitate Closing Auctions electronically or with human manual intervention. Such DMM-facilitated Closing Auctions guarantee execution of all interest priced better than the auction price, including all Market orders.1 During index rebalances, this execution guarantee is key and provides advantages over competing exchanges' (or NYSE Exchange-facilitated) closing auctions, which have pre-determined price boundaries that can cause market orders to not fully execute.
To assess the NYSE Closing Auction, we compared the volume-weighted average price during the final two minutes of trading to the closing auction price for securities that had a rebalance need. This difference, or price dislocation, indicates how well a closing process reflects market prices at the end of regular-hours trading. Lower dislocation means investors are receiving fairer prices. We found:
The NYSE Closing Auction remains the largest equity liquidity event in the world. With the NYSE Trading Floor partially re-opened, investors benefit from both the Closing Auction’s liquidity and fairer prices. These benefits are especially critical during major trading events such as index rebalances.
1 For the Russell Reconstitution all auctions were facilitated by DMMs and no securities closed via the Exchange-facilitated auction process.
2 138 NYSE securities and 271 Nasdaq securities meet this definition and had at least one trade in the last two minutes.
Following the record-setting 40.1 million average daily volume (ADV) in the 1st quarter of this year, Q2 2021 options volume was the 2nd highest of all-time with 37.6 million contracts traded per day. Robust volume was driven in part by market anticipation of a potential earlier rise in interest rates and Fed tapering, as well as increased volume in options on new issues and continued activity in retail-focused stocks.
After-hours trading has been a larger piece of the total trading volume since the onset of the pandemic, with retail presence growing stronger and earnings announcements becoming less of a factor. In this post, we examine the impact of these shifting dynamics on after-hours price discovery and order behavior.
The surge in market volatility and trading volumes since the onset of the pandemic in March 2020 has impacted numerous aspects of equity market trading. One less-studied area has been after-hours trading. After-hours has also seen changes in order flow trends and influences, and here we examine trends and shifts occurring in these sessions.
