Let take a look at the recent weekly close. A nice simple base has formed. We see the price dropped to the 8 day ma at $78.60 but ate all the way up to $86.50 and closed near the weekly high. The indicates great strength to me. Institutional buying seen here with the above average volume. Your chance to get in was at $78.60, maybe I'll get in on a break of $90. Do your own homework before investing in stocks.
