Options trading: Rebecca Darst says which dental technology firm saw “unusually bullish call activity”?

Darst also reported that options traders seem to be circling around some dental technology plays.

“It’s interesting, and I say that this is a sector play simply because we saw some unusually bullish call activity in Align Technology (ALGN), which is the company that makes Invisalign invisible braces. This was followed up yesterday by some interesting activity in Sirona (SIRO), which is a maker of hygienic equipment and dental imaging systems. We saw it straddle sellers yesterday in the July 25 contract, so people taking a premium on dental technology, that’s an area to watch.”

Align doesn’t show up on the screens I follow. Sirona has high earnings momentum, but is ranked neutrally for earnings quality, price momentum, free cash flow and return potential.
