Is ACHV or CLDX the better stock?

"Better" depends on your goal, and these two are not alike. CLDX is the larger company by market cap ($3.17B vs $822M). ACHV has been more active on our scanner (73 vs 44 alerts in 30 days). CLDX has the smaller float (74.2M vs 76.5M), which tends to mean sharper, more volatile moves. Those are the measured differences, not a recommendation, and nothing here is investment advice.

Everything above is measured from the latest completed session and SEC filings.

Which of ACHV and CLDX is more active right now?

Right now ACHV is at about 0.8x its normal volume and CLDX is at about 0.9x, so CLDX is the one drawing unusual attention today. Relative volume (RVOL) compares a stock's volume to its own recent average, so it reads the same way for a megacap and a microcap and is the quickest way to tell which of two similar names is actually in play.
