Is CLDX or QDEL the better stock?

"Better" depends on your goal, and these two are not alike. CLDX is the larger company by market cap ($3.14B vs $1.02B). QDEL has been more active on our scanner (101 vs 48 alerts in 30 days). QDEL has the smaller float (67.8M vs 78.5M), 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 CLDX and QDEL is more active right now?

Right now CLDX is at about 1.0x its normal volume and QDEL is at about 1.8x, so QDEL 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.
