Public Storage is pulling back in pre-market trading, reflecting a broader cooling trend within the real estate sector that saw peers like Digital Realty Trust decline 3.5% during the previous regular session. While institutional activity has been mixed, with Wellington Management Group reducing its position by 8.5% in the second quarter, other firms like Van ECK Associates Corp increased their holdings by 2.5% during the same period. The stock continues to trade below its 50-day moving average, and the current move follows a period of general downward pressure on REIT valuations that has persisted since the company's last earnings report.
