Why MOMO Pro Provides a "Flattened View" of Regular and Extended Hours

A recent MarketWatch article shed light on an intriguing aspect of the stock market that we have known for several years and have been meaning to share: a significant portion of daily returns are made outside of regular trading hours.

As the founder of MOMO Pro, I believe it's essential to provide our users with a seamless view of the market, incorporating pre-market, after-hours, and regular trading hours data. Our platform is designed to help investors capitalize on the moves that occur outside of regular market hours and identify potential trades as easily as regular market hours. In this blog post, we will discuss the findings of the article and explain how MOMO Pro's seamless view and Gap logic help capture these often-overlooked opportunities.

Off-Hours vs. Regular Hours Trading Pattern

The MarketWatch article highlights the U.S. stock market's historical tendency to make most of its daily moves overnight, between the closing and opening bell. Multiple academic studies confirm this pattern, including research by Oleg Bondarenko and Dmitriy Muravyev, and another study by Terrence Hendershott, Dmitry Livdan, and Dominik Rösch.

Bruce Lavine, founder of NightShares, stated that three-quarters (75%) of the 9.7% annualized return produced by the SPDR S&P 500 ETF over the 20 years through the end of 2022 occurred while the NYSE was closed. The Russell 2000 Index exhibited an even more pronounced pattern, with all of its net returns produced overnight.

How MOMO Pro Seamlessly Monitors After-Hours Moves and Identifies Potential Trades

MOMO Pro is designed to provide investors with a seamless view of the market by incorporating pre-market, after-hours, and regular trading hours data into a single coherent view.
