New database: Mutual Fund Links (MFlinks)

MFLINKS is now accessible on Wharton Research Data Services (WRDS).

Description from WRDS:

“MFLINKS provide a reliable means to join the mutual fund performance and expense information in the CRSP Mutual Fund Database (MFDB) with the equity holdings information in the Thomson-Reuters Mutual Fund ownership database (TFN/CDA S12). MFLINKS allows a researcher to gather details on holdings for either particular funds or fund families and groups of funds at specific points in time. MFLINKS has been developed with Professor Russ Wermers from the University of Maryland’s Robert H. Smith School of Business, as a contributor and ongoing consultant to the project. Professor Wermers was one of the first researchers to use linked mutual fund data. A good example of how MFLINKS can be used is his article, “Mutual Fund Performance: An Empirical Decomposition into Stock-Picking Talent, Style, Transactions Costs, and Expenses” (Journal of Finance, 2000). It decomposes mutual fund performance into its various components based upon actual holdings.

MFLINKS provides links between the 98% of the domestic equity funds in CRSP and Thomson-Reuters. The database consists of two tables that provide the mapping between CRSP and Thomson-Reuters mutual fund identifiers, to a common Wharton Financial Institution Center Number (WFICN), which is a unique and permanent fund portfolio identifier. There are 23,340 WFICN-CRSP_FUNDNO pairs in MFLINKS Table 1, including 4,600+ new links added in the 2013 update. There are 8,476 FUNDNO-WFICN pairs in MFLINKS Table 2, including 1,850 new links added in the 2013 update.”

New database: Markit

Columbia Libraries is pleased to announce that now we have access to Markit via Wharton Research Data Services (WRDS). Columbia Libraries subscribe to Markit services including CDS Pricing (End of Day) and RED-CDS (Full Service).

From the WRDS website:

Markit CDS Pricing: Provides CDS composite and contributor level data on approximately 2,800 individual entities. Applying a data cleansing process, Markit aggregates marks from sell-side contributors to generate its composite price.  The data are provided on a daily basis starting in 2001 (with 810 reference entities) and are available by entity, tier, currency and restructuring clause.

RED (Reference Entity Database):
a database of confirmed Reference Entities and their Reference Obligations for use in trading, documenting, and processing credit derivatives transactions. A Reference Entity is an institution, such as a company, a sovereign, a statute-created entity, or a multilateral institution, that has either issued or guaranteed an obligation (a Reference Obligation). These Reference Obligations are typically issuances of debt obligations, but on occasion they may also be non-debt securities (such as preference shares). Pairs of Reference Entities and their associated Reference Obligations (Pairs) form the basis of RED.  RED provides a means of linking CUSIP and ISIN to other Markit databases (e.g. CDS) which are identified by the Markit primary id (REDCODE).  RED also allows the data user to track CDS reference entities through mergers, de-mergers and other corporate actions.”

Updated TAQ data available in WRDS


2009 data from the NYSE Trade and Quote [TAQ] database is now available via the Wharton Research Data Service [WRDS].

Watson Library: new dataset available via WRDS

wrdsThe Watson Library now subscribes to the shareholder proposals section of RiskMetrics via WRDS   This adds to our current RiskMetrics subscription to the governance and directors modules.  RiskMetrics was previously knows as IRRC.

The shareholder proposals module (governance and social responsibility) contains data from 1997 through 2007. The dataset includes proposals that came to a vote as well as those that did not (e.g., because they were withdrawn by the proponent or allowed to be omitted from the proxy by the SEC). Variables include the lead filer of the proposal, the meeting date, and outcome; some fields are not complete every year for every company, but the vast majority of meeting dates are present.
