A 50% gap fill would take us down to about $60.93 (say $61) and the 50sma is currently at $61.45. Stochastics are oversold in the extreme (%K 2.99), RSI(21) = 47.99. Currently skimming the bottom of the Keltner Channel.
Recent upgrade (9/18) by Thomson Reuters/Verus from HOLD to BUY (We've come down 7.8% from that point). 15.5% pullback from 52 wk high so far.
I'd say the $61 area might be a good place for an initial scale in entry.
