A couple of weeks ago, I noted that Ameritrade $AMTD was bullish in the short-term, but was likely going to find resistance in the $47-$48 area. TD Ameritrade (AMTD) Pulls Up from $42.15 But Has Key Resistance in the $47-$48 AreaAMTD Daily Chart(click to enlarge)Bears in Charge:- As we can see on the daily chart, the prevailing trend is bearish.- After consolidating for most of 2019, price broke down into new lows. When it rebounded from a support just above $42, it came back into the consolidation range. - I suspected resistance at the previous support area, but price kept pushing to $50. - Retreating from $50 still keeps AMTD in a bearish trend, especially with the downwards acceleration during the 9/26 session accompanied by strong volume.- The strong retreat along with the headlines should be able to turn AMTD back into the bearish trend.- If price indeed comes down to challenge the support around $42, I suspect a breakdown to $40 before support, with $36, 2017-low as the potential target.
