The outpatient rehabilitation segment consists of clinics that provide physical, occupational, and speech rehabilitation services.
SEM trades on NYSE and is tracked by the PennyStock.Ninja real-time scanner. The scanner monitors SEM for premarket gaps, unusual relative volume (RVOL), VWAP reclaims and rejections, and vibe signals such as the Surfer breakout, Ninja stealth accumulation, and Fade caution patterns. Biotech and healthcare names like this one are highly catalyst-driven — FDA decisions, clinical trial results, and PDUFA dates can move the stock 50-200% in a single session, so position sizing and stop discipline matter more here than in any other sector.

Frequently asked questions about SEM
Why is SEM moving today?
SEM (Select Medical Holdings Corporation) moves on relative volume (RVOL), VWAP behavior, sector rotation, and catalysts like earnings, FDA decisions, contract wins, or unusual options flow. See the live "Why is SEM moving today?" panel above for an auto-generated read on today's tape, and the news section for current headlines.
Is SEM a good penny stock to buy?
PennyStock.Ninja does not give buy or sell recommendations on SEM. We give you the data — live RVOL, VWAP, float, short interest, analyst consensus, and vibe signals — so you can make your own decision. Always do your own research and never risk more than you can afford to lose.
What is SEM's RVOL and why does it matter?
RVOL compares SEM's current volume to its 30-day average. RVOL above 3× often signals a real catalyst — but watch the price action. High RVOL with the stock dumping below VWAP is distribution, not opportunity.
When does SEM report earnings?
Earnings dates for SEM are tracked in the PennyStock.Ninja scanner. See the "Upcoming Catalysts" panel above for the scanner's current estimate. Select Medical Holdings Corporation typically reports quarterly; check the company's investor relations page for the next confirmed date.
What is SEM's float and short interest?
SEM float is shown in the "Short Interest & Float" panel above. Low-float names (under 75M shares) with elevated short interest can squeeze violently — always check both before sizing into a momentum trade. Live short interest, days-to-cover, and the Ninja Squeeze Score are members-only.
