A new Form 4 filing with the SEC on Monday revealed that Goldman Sachs Group virtually sold its entire $1.1 billion stake in TransUnion (NYSE: TRU). Analyzing the company’s fundamentals help explain why Goldman sold its shares.

Goldman Exits TransUnion

On February 14th, Goldman Sachs Group filed its quarterly 13F regulatory filing. The filing showed that the investment firm held 19,855,632 shares of TransUnion worth $1.1 billion as of December 31st. Note that this represented only 0.26% of Goldman’s massive $418 billion portfolio.

However, a new filing yesterday revealed that the investment firm sold 19,852,972 shares on March 8th at an average price of $57.60 per share. This reduced Goldman’s position in the company to virtually 0%. Goldman, along with buyout shop Advent International, had originally bought TransUnion for $3 billion in 2012.

TransUnion’s shares last traded at $58.02 as of Monday’s close, up 54.3% over the prior year. While shares have significantly appreciated in value, could the recent insider selling activity signal the stock is overvalued?
