| Public Storage is a real estate investment trust. Co. acquires, develops, owns and operates self-storage facilities, which provide storage spaces for lease on a month-to-month basis, for personal and business use. Co. is an owner and operator of self-storage facilities in the U.S. in most primary markets and states. A wholly-owned, consolidated subsidiary of Co. reinsures such policies and thereby assumes various risk of losses under these policies and receives reinsurance premiums substantially equal to the premiums collected from its tenants, from the non-affiliated insurance company. In addition, Co. sells merchandise, primarily locks and cardboard boxes at its self-storage facilities.
When researching a stock like Public Storage, many investors are the most familiar with Fundamental Analysis — looking at a company's balance sheet, earnings, revenues, and what's happening in that company's underlying business. Investors who use Fundamental Analysis to identify good stocks to buy or sell can also benefit from PSA Technical Analysis to help find a good entry or exit point. Technical Analysis is blind to the fundamentals and looks only at the trading data for PSA stock — the real life supply and demand for the stock over time — and examines that data in different ways. One of those ways is to calculate a Simpe Moving Average ("SMA") by looking back a certain number of days. One of the most popular "longer look-backs" is the PSA 200 day moving average ("PSA 200 DMA"), while one of the most popular "shorter look-backs" is the PSA 50 day moving average ("PSA 50 DMA"). A chart showing both of these popular moving averages is shown on this page for Public Storage.
