I wouldn't worry too much about this - the company beat on earnings, but the concern was that some of it came from PCLs in which it posted a recovery (not a loss). I believe it was the only bank to post a recovery in this area and not a loss. This is why some believe earnings were positively inflated. It also posted flat loan growth in the US so that was also a concern in terms of growth prospects.
In is important to note, ALL banks reported big decreases in PCLs - it'll be interesting to see how it plays out next quarter but overall, 1 quarter for TD Bank is absolutely nothing to worry about. As you mentioned, It rose quite nicely over the past few months and it even rebounded a little on Friday/.
