Should We Leave the Ark Alone?

ARKK was a great target for shorts over the past year, but does it still have good targets? I decided to hone in on the stocks that ARK controls 9 percent or more of, along with ROKU, EXAS and PATH which are top-10 holdings of significant size. I calculated how many days of average volume it would take ARK to sell out of its holding. The largest of these are MTLS, DYNS, QSI, SGFY, PSNL, VCYT and BEAM. It would take ARK between 10 and nearly 19 days to clear out its holdings at recent average volume.

A bunch of stocks on the list are low priced and/or recent IPOs. Of note, several of the charts have vertical plunges. The charts below look the most interesting, but not all of them are good short candidates for various reasons. I'd hone in on the larger cap ones with options for myself. Worth noting that a lot of these are biotechs and they look like the biotech ETFs, pasted below.
