Is KLAC or COHR the better stock?

"Better" depends on your goal, and these two are not alike. KLAC is the larger company by market cap ($270.31B vs $66.00B). COHR has been more active on our scanner (203 vs 171 alerts in 30 days). COHR has the smaller float (195.8M vs 1.31B), which tends to mean sharper, more volatile moves. Those are the measured differences, not a recommendation, and nothing here is investment advice.

What is the difference between KLAC and COHR?

The differences that matter: KLAC is roughly 4x the size of the other by market cap ($270.31B vs $66.00B); they trade at very different share prices ($207.35 vs $337.79); KLAC sits at 52% of its 52-week range against 69% for COHR; only KLAC pays a dividend; our scanner flagged KLAC 171 times in the last 30 days against 203 for COHR. Everything above is measured from the latest completed session and SEC filings.

Which of KLAC and COHR is more active right now?

Right now KLAC is at about 0.8x its normal volume and COHR is at about 1.5x, so COHR 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.
