Is SION or IRD the better stock?

"Better" depends on your goal, and these two are not alike. IRD is the larger company by market cap ($434M vs $271M). IRD has been more active on our scanner (265 vs 95 alerts in 30 days). SION has the smaller float (32.0M vs 81.4M), 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 SION and IRD?

The differences that matter: they are similar in size ($271M vs $434M); they trade at very different share prices ($5.97 vs $5.18); SION sits at 4% of its 52-week range against 66% for IRD; our scanner flagged SION 95 times in the last 30 days against 265 for IRD. Everything above is measured from the latest completed session and SEC filings.

Which of SION and IRD is more active right now?

Right now SION is at about 0.7x its normal volume and IRD is at about 0.5x, so SION 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.
