PCLA +191% Intraday MFE Leads 20-Ticker 5x RVOL Surge: May 22 Data Digest
20 small-caps cracked 5x RVOL on May 22, capping a runner-heavy week. PCLA, AKTX, CODX, MTVA, and AMST printed +157% to +436% gains with 100% pattern follow-through.
TLDR
- 20 tickers cracked 5x relative volume on May 22, capping a runner-heavy week with 48 names gaining 50%+ and 10 cracking 100%+ across the small-cap universe
- PCLA (Communication Services) printed +388.9% close-to-close over 5 days; the May 21 session offered a +191.5% intraday MFE from low ($1.41) to pre-market high ($4.11) on 45.3M shares at 7,878.6x ADV
- 180 scanner patterns triggered with 100% follow-through across the week — 26% above the 90-day weekly baseline of 142.9
- Pharmaceuticals (+245% RVOL week-over-week) and Consumer Defensive (+1,419%) led sector rotation
- Macro backdrop is Broad Strength with Small-Caps Participating — Russell 2000 (IWM) sits -0.9% from its 52-week high at $285.12
Friday's tape pushed 20 small-caps past 5x relative volume — a continuation of last week's runner-heavy character that produced 4 names with 200%+ close-to-close gains in 5 sessions. The featured 5 ran +157.7% to +436.3% over the week (May 18–22), with PCLA, CODX, MTVA, and AMST all printing constructive multi-day base structures rather than single-day exhaustion candles.
Below is the full forensic breakdown — the multi-day runners, the volume spikes, the filing activity behind the moves, and the exact scanner configuration that surfaced these names before they ran.

Featured Runners: 5 Tickers, 5 Days, +157% to +436%
The week's leaderboard sorted into a clean tier — pharmaceuticals and communication services dominated the top half, services rounded out the bottom. Here's the data, ranked by 5-day split-adjusted gain:

PCLA — Communication Services, +388.9% Over 5 Days
PCLA was the cleanest setup of the week. The 5-day arc ran from a $1.35 open on May 18 to a $6.60 close on May 22 (+388.9%) on 81.2M total shares.
The May 21 session was where the meat of the move printed. Pre-market high tagged $4.11, the regular session opened at $1.73, low was $1.41, high was $2.64, close was $2.34 (+35.6% on the regular session). But the TRUE intraday MFE — low to high across all sessions — was +191.5%. Single-day volume was 45.3M shares at 7,878.6x ADV — a top-5 RVOL print in the entire active universe last week.
Cash runway sits at 3-6 months per the dilution tier classification. That puts PCLA in the cohort where a financing event sits on the near-term clock — exactly the window where market makers and the company itself have a structural incentive to push the stock higher before pricing any offering at a better level.
A $10,000 position at the May 21 low ($1.41) selling at the pre-market high ($4.11) returned $29,150 (+191.5%). The more realistic open-to-close trade ($1.73 to $2.34) captured $13,526 (+35.3%).
AKTX — Pharmaceuticals, +436.3% (Post-Split Rebase)
AKTX printed the largest headline number but carries a post-split rebase flag — the close-to-close calculation reflects a split adjustment over the period. The clean way to read this one: 34M shares traded on the peak session, the ticker now sits at $18.18 vs an open-of-week reference at $3.39. With 26 active facilities and 16 completed offerings on file, the structural overhang is heavy — this is a momentum vehicle, not a clean float story. Position-sizing here demands tighter stops than the others.
CODX — Medical Instruments, +268.8% Over 5 Days
CODX moved from $1.38 to $5.09 on 235.9M total shares — the highest aggregate volume on the featured list. Single-session peak: 119.8M shares. The 5-day arc is the textbook continuation pattern — break, base, break, base, break — that the scanner's liquidity-test detector flags when market makers probe supply at successive levels before each leg up. The third pharmaceutical-adjacent name in the featured 5; sector rotation tailwinds matter.
MTVA — Pharmaceuticals, +250.5% Over 5 Days
MTVA ran from $1.10 to $3.85 over 5 days on 192.0M shares with a single-day max of 85.1M. The Pharmaceuticals sector posted a +245% week-over-week RVOL increase — when an entire sector is rotating in, individual setups in that sector get a tailwind. MTVA was a beneficiary.
AMST — Services, +157.7% Over 5 Days
AMST ran from $0.83 to $2.15 on 182.0M total shares (146.9M single-day peak). At sub-dollar pricing entering the week, AMST printed the highest dollar-volume velocity per share of the featured five — the kind of name that rotates through every momentum trader's watchlist once the volume profile breaks open.
Pattern Activity: 180 Setups, 100% Follow-Through
180 scanner patterns triggered in the past 7 days — meaningfully above the 90-day weekly baseline of 142.9 (about 26% above average). Every single one resolved:
- 51 stocks with 100%+ intraday gains triggered and all 51 reached completion
- 35 stocks that traded 100M+ shares intraday triggered and all 35 hit target
- 94 liquidity-test setups (where market makers probe supply at key price levels, or insiders quietly build position before a catalyst) triggered and all 94 completed
Follow-through rate stands at 100% across the full 180-pattern cohort. That's the signature of a tape where setups are getting paid — when follow-through degrades, breakouts fail and chop dominates. We are not in that state.
The forensic edge here matters: when the universe is producing 35 separate 100M+ volume events in a week with no failures, the supply/demand mechanics are heavily skewed. Each of the featured 5 fired multiple of these patterns over the 5-day arc — PCLA's May 21 was a textbook liquidity-test followed by intraday-doubling sequence.
Filing Activity: Active Dilution Chain Behind the Moves
The active universe currently carries approximate counts of ~5,400 active warrant facilities, ~2,900 active shelf registrations, ~1,900 active ATM programs, ~1,300 active convertible note facilities, ~800 active convertible preferred facilities, ~600 active S-1 offerings, and ~500 active equity lines.
In the past 3 days:
| Filing Type | Filings | Unique Tickers |
|---|---|---|
| 8-K | 125 | 120 |
| 424B3 | 11 | 6 |
| 424B5 | 9 | 8 |
| S-3 | 7 | 7 |
| S-3/A | 4 | 4 |
| F-3 | 3 | 3 |
| S-1/A | 2 | 2 |
| S-1 | 2 | 2 |
| 424B2 | 1 | 1 |
That filing pace is the load-bearing context behind the week's moves. When a ticker breaks out on heavy volume and then files a 424B5 the next morning, the structural sellers are already lined up — the run was the financing window.
For traders, the playbook here is asymmetric:
- The risk side (well understood): buying into dilution leaves you on the wrong side of mechanical supply when the shelf comes off
- The opportunity side (less appreciated): market makers and the company itself often have a structural incentive to push the stock UP before pricing the deal at a higher level. The pre-financing run is a tradable structure if you respect the exit

Sector Rotation: Where Capital Is Moving
Week-over-week RVOL shifts across active small-caps tell the rotation story clean:

Three of the featured 5 runners sit in Pharmaceuticals or Medical Instruments — capital is rotating into the sector and individual setups are catching the flow. Consumer Defensive's +1,419% week-over-week RVOL change is the largest single-sector shift in the data — we covered the leading edge of that rotation in HCWB +584% in 5 Days as Consumer Defensive Rotates In.
Oil & Gas (+849% week-over-week) is the second-largest rotation and has no featured-5 representation — that's the gap the scanner should be watching for this week. When a sector is rotating in heavily but no name from that sector has run yet, the asymmetric setup is finding the catalyst-driven name in that sector first.
Macro Backdrop: All Four Indices Within 1% of 52-Week Highs
All four major ETF proxies sit within 1% of their 52-week highs:
- S&P 500 (SPY): $745.64, -0.5% from 52-week high ($749.53), +0.9% over 5 days, +4.4% over 20 days
- Nasdaq 100 (QQQ): $717.54, -0.6% from 52-week high ($722.12), +1.2% over 5 days, +8.1% over 20 days
- Russell 2000 (IWM): $285.12, -0.9% from 52-week high ($287.58), +2.7% over 5 days, +3.1% over 20 days
- Dow Jones Industrial (DIA): $506.12, -0.5% from 52-week high ($508.74), +2.2% over 5 days, +2.8% over 20 days
Russell 2000 (IWM) leading the 5-day move at +2.7% while sitting -0.9% from its 52-week high is the small-cap macro tell. The macro call is Broad Strength with Small-Caps Participating — when small caps participate at the index level, individual breakouts in the active universe have better follow-through. The 100% pattern follow-through this week is consistent with that backdrop.
Same-Weekday History: Mondays Are Running Hot
This digest publishes on a Monday. Same-weekday history for the last four Mondays:
| Date | Top Mover | Movers ≥ 50% |
|---|---|---|
| 2026-04-27 | HTCO +192% | 3 |
| 2026-05-04 | SKK +596% | 4 |
| 2026-05-11 | WOK +148% | 5 |
| 2026-05-18 | WGRX +88% | 2 |
Average top gain across the last 4 Mondays: +256.2%. That is materially elevated vs the 4-week baseline of ~8.5 runners ≥ 50% per week. Last week alone produced 48 runners ≥ 50% — about 5.6x the baseline. The week-arc data shows 4 of the last 7 weeks were runner-heavy Mondays, and none of those weeks faded to a quiet Friday — energy carries through.
What's Setting Up
Macro structure is constructive: indices at 52-week highs with breadth, small-caps participating, 100% pattern follow-through, sector rotation broad. The configurations that fired last week — multi-day continuation pharmaceuticals, sub-$3 services and communication services with constrained float and shelf overhang, liquidity-test patterns at intraday levels — are the configurations to scan for this week.
The forward-looking watch items:
- Continuation in PCLA, CODX, MTVA, AMST — multi-day runners typically print a Monday gap-and-go or Monday fade-and-reclaim. Both are tradable; the read is who's left holding from Friday. PCLA's $6.60 close into Monday morning is the decision point
- Pharmaceuticals sector RVOL — +245% week-over-week is the third-largest sector rotation. Set the sector filter to Pharmaceuticals + RVOL > 5x to catch the next AKTX/MTVA-type setup
- Oil & Gas (+849% W/W RVOL) — no featured-5 representation but the second-largest rotation. The next breakout from this sector has the cleanest asymmetric setup of the week
- Active filing chain — 9 fresh 424B5 pricing supplements in 3 days means the dilution chain is active. Tickers that print 100%+ runs this week with pending shelf overhang are the textbook pre-deal pump structures
Scanner Setup of the Week: "5x RVOL Continuation Candidates"
The exact configuration that surfaced this week's runners — save this as a named preset with a color tag:
- Price: $0.50 – $20.00 (the small-cap zone where the runners actually live)
- RVOL: ≥ 5x (cuts the noise to the active 1–2% of the universe)
- Volume: ≥ 5M shares (filters out illiquid tickers — featured 5 all printed 30M+ on single sessions)
- Float: under 100M shares (the supply constraint that enables the move)
- Sector: Pharmaceuticals OR Consumer Defensive OR Services OR Communication Services OR Oil & Gas (where the rotation is)
- Sort: RVOL descending
Save the filter as a named preset in the SNACS scanner. Then link the saved scan to a Dynamic Watchlist — any ticker that matches the filter in real time gets a colored square in your main stream, so you don't have to flip between tabs. When the colored square appears next to a sector-aligned ticker with active shelf overhang, that's your alert.
For the dilution check: click any ticker in the scanner to open the ticker details page. The dilution risk panel surfaces the active shelf, ATM, and warrant facilities — same data as the SEC research dilution snapshot — so you can verify whether the move is happening with a shelf above or a clean structure underneath before you size in.
For pattern alerts: build a setup in the AI Playbook Builder that watches for the multi-day continuation structure (Day 1 breakout on 100M+ volume → Day 2 base → Day 3 next leg). Live matching puts a star indicator next to every ticker hitting that pattern in real time across the 2,500+ ticker stream.
How to Manage the Trade
A framework — not financial advice:
- Entry: the cleanest entries on these multi-day continuations are the morning re-test of the prior day's close after a pre-market gap. PCLA on May 21 gapped pre-market to $4.11, opened the regular session at $1.73, and the low was $1.41 — that re-test was where the +191.5% MFE started
- Stop: under the morning low or under the prior day's close, whichever is wider for the volatility profile
- Take-profit zones: scale into 100% MFE, 150% MFE, and 200% MFE. The 100% pattern follow-through right now means setups are paying, but they pay in the first leg — late entries get less
- The dilution risk: if a 424B5 prices overnight, the gap-down can take out the morning low instantly. Check the ticker details page for active shelf status before holding overnight
Multi-day runners get most of their move in the first 2 sessions. By Day 5 the structure is mature and reversals get sharper. The pharmaceutical and services names featured this week are now in that mature zone — Monday's action is the tell on whether the structure continues or hands off to a reversal trade.
For traders running a journal: tag these multi-day continuation entries with the setup name and the day-of-arc (Day 1 / Day 2 / etc.). The trading journal AI Insights surface where in the arc your edge actually compounds — most traders find Day 2-3 is the highest hit rate, while Day 5+ has the wider tails.
Conclusion
Last week (May 18–22) was a runner-heavy continuation of an already runner-heavy 4-Monday stretch. 48 names ≥ 50% vs an ~8.5 weekly baseline. 10 names ≥ 100%. 4 names ≥ 200%. Pattern follow-through at 100% across 180 setups. Macro constructive with small-caps participating at index level. Sector rotation broad enough to give every active scanner user multiple sector lanes to fish.
The featured 5 — AKTX +436%, PCLA +389%, CODX +269%, MTVA +250%, AMST +158% — are now in mature continuation zones. This week's task is identifying the next cohort: same configuration (5x RVOL, sub-$20, sub-100M float, sector-aligned with the rotation), same filing patterns (shelf overhang creating pre-deal supply tension), same chart structure (multi-day base-and-break).
The scanner does the surfacing. The dilution panel does the structural check. The playbook does the pattern alert. The work that's left for the trader is the entry, the stop, and the exit — and that's where the journal data compounds week over week.
FAQ
What is RVOL and why does 5x matter for day trading?
RVOL (Relative Volume) compares today's volume to the stock's historical average. A 5x RVOL means today's volume is five times normal, signaling a catalyst, news, or institutional flow large enough to break the stock out of its typical activity baseline. 5x is the threshold where small-cap moves stop being noise and start being trades.
How did 20 tickers hit 5x RVOL in a single session?
Last week's tape was runner-heavy by every measure — 48 names with 50%+ gains, 10 with 100%+ gains, sector rotation across Pharmaceuticals, Consumer Defensive, and Oil & Gas. When the macro backdrop is Broad Strength with Small-Caps Participating (Russell 2000 sitting -0.9% from its 52-week high) and pattern follow-through hits 100%, simultaneous breakouts cluster like this.
What's the difference between MFE and the close?
MFE (Max Favorable Excursion) is the best possible trade from the day's low to the day's high across all sessions (pre-market, regular, after-hours). A stock can close red but still have offered a +191% MFE — that's the trader's edge over the buy-and-hold reader. PCLA on May 21 closed +35.6% on the regular session but offered a +191.5% intraday MFE.
Why are SEC filings important to check before a momentum trade?
Filings reveal the structural supply behind a stock. A ticker breaking out with a fresh S-3 shelf above its head has different mechanics than one with a clean structure. The dilution risk panel in the SNACS scanner ticker details page surfaces active shelf, ATM, and warrant facilities — the same data as the SEC research dilution snapshot.
What is a liquidity test pattern?
A liquidity test is when market makers sweep a price level to test supply and demand before the real move — or when insiders are quietly building positions before a catalyst. In the scanner it appears as a tight intraday probe at a key level (prior day close, round number, premarket high) followed by either a sharp reversal or a controlled continuation. The pattern fired 94 times last week with 100% follow-through.
How do I find the next AKTX or PCLA before they run?
Set the SNACS scanner RVOL filter to 5x minimum, price range $0.50–$20, float under 100M, and sort by RVOL descending. Add a sector filter for the sectors currently rotating in (Pharmaceuticals, Consumer Defensive, Communication Services, Oil & Gas). Save the filter as a Dynamic Watchlist so matches auto-populate in real time. When a sector-aligned ticker with shelf overhang appears, that's the watch.
Are small-cap earnings reports tradable catalysts?
No — small-cap earnings are rarely the actual catalyst. The real drivers in the sub-$500M market cap zone are SEC filings (S-3, 424B5, ATM activity), FDA actions, contract wins, insider buying, and unusual volume. If a small-cap ticker is moving without a filing or news driver, look for accumulation in the float and volume data — that's often the unstated catalyst.
How long do multi-day runner setups continue?
Most multi-day continuations get their largest moves in the first 2 sessions and become reversal-prone by Day 5. The featured 5 (AKTX, PCLA, CODX, MTVA, AMST) closed the week at Day 5 of their respective arcs — this week's action is the tell on whether each transitions to a fresh leg or hands off to a reversal trade.
