Is COP or SUN the better stock?

"Better" depends on your goal, and these two are not alike. COP is the larger company by market cap ($155.39B vs $13.75B). COP has been more active on our scanner (129 vs 77 alerts in 30 days). Both are petroleum refining names, so this is a like-for-like comparison and sector news tends to move them together. Those are the measured differences, not a recommendation, and nothing here is investment advice.

What is the difference between COP and SUN?

The differences that matter: COP is roughly 11x the size of the other by market cap ($155.39B vs $13.75B); they trade at very different share prices ($129.84 vs $71.75); COP sits at 79% of its 52-week range against 73% for SUN; our scanner flagged COP 129 times in the last 30 days against 77 for SUN. Everything above is measured from the latest completed session and SEC filings.

Which of COP and SUN is more active right now?

Right now COP is at about 0.9x its normal volume and SUN is at about 0.8x, so COP 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.

Is this comparison data live?

Prices and % changes are anchored to the latest completed session and split-adjusted, so a reverse split never shows as a fake move. Float is estimated from SEC filings and refreshed as new filings publish.
