What Happened?
Shares of infrastructure construction company MasTec (NYSE:MTZ) fell 4.5% in the morning session after a regulatory filing showed a significant institutional investor had trimmed its position in the company.
A 13F filing with the Securities and Exchange Commission, reported on Tuesday, revealed that Los Angeles Capital Management LLC had lessened its stake in the construction company by 64.9% during the first quarter. The disclosure of this large institutional sale may have concerned investors. Further pressure may have come from reports of recent insider activity; a filing showed MasTec's Chief Operating Officer, Robert E. Apple, sold 10,000 shares of company stock on July 16. The decline in the share price came despite positive commentary from Wall Street. On the same day, analysts at JPMorgan raised their price target on MasTec to $214 from $180 and maintained an "overweight" rating on the stock.
