These are the top 10 holdings of the Mormon Church's $51 billion stock portfolio

The Church of Jesus Christ of Latter-day Saints pared back its exposure to mega-cap tech stocks during the fourth quarter.

• The investment arm of the Mormon Church revealed some of its holdings in a 13F filing on Wednesday.
• The church has amassed a portfolio of individual stocks worth more than $50 billion.
• These are the top 10 holdings of the Mormon Church's stock portfolio as of December 31.

The Church of Jesus Christ of Latter-day Saints' has an investment portfolio of over $100 billion that includes $51 billion invested in publicly traded stocks.

The portfolio is registered with the SEC under the name Ensign Peak Advisors, and its ties to the Church of Jesus Christ of Latter-Day Saints was largely unknown until recently.

The portfolio wasn't revealed to the public until 2019, when a former Ensign Peak employee filed a whistleblower complaint, alleging that the fund shouldn't have tax-exempt status because it doesn't engage in any charitable activities.

In a "60 Minutes" special last year, the whistleblower said that the church's investment arm acted as a "clandestine hedge fund" disguised as a charity.

The church reports its stock holdings on a quarterly basis, and a recent 13F filing revealed its top holdings as of December 31. During the quarter, the fund trimmed its concentration in mega-cap technology stocks.

These are the Mormon Church's top 10 stock holdings at the end of the fourth quarter, as well as the changes in each position.
