Frequently asked questions about ERII
Why is ERII moving today?

See the live "Why is ERII moving today?" panel above for an auto-generated read on today's tape, and the news section for current headlines.
Is ERII a good penny stock to buy?
PennyStock.Ninja does not give buy or sell recommendations on ERII. 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 ERII's RVOL and why does it matter?
RVOL compares ERII'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 ERII report earnings?
Earnings dates for ERII are tracked in the PennyStock.Ninja scanner. See the "Upcoming Catalysts" panel above for the scanner's current estimate. Energy Recovery, Inc. typically reports quarterly; check the company's investor relations page for the next confirmed date.
What is ERII's float and short interest?
ERII 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.
