To our valued subscribers, partners, and friends of CRSP:

CRSP places the utmost priority on the safety and well-being of our colleagues, clients and business partners. As concerns surrounding COVID-19 have increased impact on our communities, it is important to provide details on the actions and precautions we are taking.

Safety and continued service are our priorities and we are monitoring the constantly changing situation. In light of CDC guidelines, we have implemented our Business Continuity Plan. It is functioning as intended. Many CRSP staff members have moved to our work-from-home (WFH) policy. We have added a number of collaboration and connectivity tools, intended to make both our staff and subscriber experiences as smooth as possible.

Our staff’s physical location should not hamper our ability to serve clients. Our teams are closely monitoring developments and collaborating on the best courses of action.

We at CRSP, wish you all good health. We express gratitude for the trust our clients and partners place in us.

Be well.

David Barclay CEO, Center for Research in Security Prices, LLC

CRSP Equity Index March Ranking and Reconstitution Update

The Center for Research in Securities Prices LLC (“CRSP”) has determined to postpone the ranking and reconstitution process of all of its its equity indexes until June. Pursuant to the declaration of a National Emergency, the universal acknowledgement that the current situation requires the continuance of orderly processes, and because of increased industry uncertainty and operational risk that may impact the ability to respond to additional events, CRSP believes that this is the necessary course of action. 

What this means to our index clients and concerned market participants is: 

  • When the market opens on Monday, March 16, 2020, there will be no CRSP pro-forma indexes for a March 2020 rebalancing. Constituents and weights for the primary indexes will remain unchanged, except for adjustments needed for our existing policy of applying corporate actions for continued maintenance. The prospective pro-forma indexes for the March ranking and reconstitution period are therefore no longer valid, and December 2019 breakpoints will remain in place for the primary indexes until the June ranking. 
  • We expect the June 2020 ranking to remain as scheduled. 

CRSP continues to monitor the COVID-19 situation closely, including the work of the CDC, World Health Organization and other government agencies, and will communicate with our clients and update our policies as appropriate.

The Democratization of Investment Research: Implications for Retail Investor Profitability and Firm Liquidity

Investment research is increasingly produced outside of Wall Street. The ability of retail order imbalances to predict future returns is twice as large on days SA research is published, and the relation is stronger for articles that generate more comments or are written by skilled contributors.
