American Tower director buys $500K of stock

American Tower director Rajesh Kalathur purchased 2,800 shares of $AMT on August 21, according to a regulatory filing.
The transaction was worth approximately $500,700.
Open-market insider purchases can be worth tracking because directors are putting personal capital directly into the company rather than receiving shares through compensation.
For $AMT, the purchase adds a small but notable insider-confidence signal.
