Apple stock isn’t doing that great today following the announcement of major executive level shifts in the company earlier this week. AAPL dipped slightly below 600 following Apple’s Q4 earnings call earlier this month, which many thought was due to less than expected iPad sales for the quarter. Today AAPL is floating under the 590 mark as concerns over iPad shortages leading into the holidays continue to increase. This puts AAPL at its lowest levels since July.
