Penny Stocks to Buy This Week: How to Build a Research-Backed Watchlist

TLDR:

• 16 stocks doubled intraday this week with 95 total scanner patterns detected — 18% below the 90-day weekly average of 116, meaning selectivity matters more than ever
• SKLZ delivered +515.4% MFE ($3.25 to $20.00) on a jury verdict catalyst — a $10,000 position at the low returned $51,540 in profit
• CHSN collapsed -92.7% in a single session with no identifiable catalyst — the week's clearest reminder that volume alone is not a setup
• 32 offering-related SEC filings hit in 3 days (16 424B5s + 16 424B3s) — every watchlist candidate needs a dilution check before entry
• The difference between winners and losers last week came down to one thing: verified catalysts before the move

The phrase "penny stocks to watch this week" gets searched thousands of times every Monday. Most of the articles ranking for it are listicles written by people who don't trade — five tickers pulled from a screener with zero context on why they moved or whether the setup was actually tradeable.

This isn't that article. This is a framework for building a watchlist that would have caught SKLZ before its +515.4% MFE spike, filtered out CHSN before its -92.7% collapse, and identified the exact volume and filing signals that separated the week's real setups from its traps.

What a Research-Backed Watchlist Actually Looks Like

A research-backed watchlist filters candidates through three layers: unusual volume, a verified catalyst, and a clean dilution profile. Most traders only use the first one — and that's why most traders lose on penny stocks.

The scanner is layer one. It finds the names. But the scanner alone showed 95 pattern detections last week across all categories: 25 tickers trading over 100 million shares, 16 that doubled intraday, and 54 liquidity tests where market makers probed key price levels. That's a lot of noise. The 90-day weekly average is 116.3 patterns, so this week was actually 18% below normal — fewer opportunities, which means being selective was even more critical.

Layer two is the catalyst. Of the tickers that moved big last week, the ones that held their gains almost always had a verifiable press release or SEC filing behind the move. The ones that faded — or outright collapsed — didn't.

Layer three is the dilution check. With ~2,000 active ATM programs, ~5,400 active warrant facilities, and ~2,900 shelf registrations tracked across the platform, any stock on your watchlist could be actively selling shares into your trade. If you skip this step, you're trading blind.

Let's walk through last week's data and show exactly how each layer would have worked.

Last Week's Winners (Apr 20-24): Catalyst + Volume = Edge

The best setups last week all shared two characteristics: they had massive relative volume AND a confirmed news catalyst that explained the move. Here's the breakdown.

SKLZ — +515.4% MFE on a Legal Victory

SKLZ opened at $3.62 on April 23, dipped to a session low of $3.25, and ripped to $20.00 before closing at $12.44 — a +243.6% market close and a +515.4% MFE from the day's low to high. Volume was 31.4M shares.

The catalyst: Skillz issued a statement on a jury verdict in their favor. This was verifiable before the move — the press release hit via Business Wire on April 23. A trader scanning for unusual premarket volume ($3.69 PM high on thin activity) and cross-referencing the news feed would have had this on their watchlist before the market open.

A $10,000 position at the $3.25 low capturing the full MFE to $20.00 would have returned $51,540 in profit (+515.4%). The more conservative open-to-close trade: $10,000 at $3.62 open to $12.44 close = $24,365 profit (+243.6%).

After-hours told the real story — SKLZ faded to $8.81 AH. Traders who held through close gave back significant gains. This is why MFE matters: the opportunity existed, but only for those who managed the exit.

YAAS — +176.6% MFE, Closed +60.9%

YAAS ran on April 27 with 179.9M shares traded at 3,288x its average daily volume. The full-day range was $0.93 to $2.57, giving a +176.6% MFE. Market close was $2.33, meaning this one actually held — rare for a penny stock runner.

The catalyst: Youxin Technology announced a strategic acquisition of YATOP worth $10.8M in shares to expand its TikTok ecosystem and digital commerce capabilities (6-K filing, April 27). This is exactly the type of catalyst that holds — a tangible business expansion with a specific dollar figure attached.

A $10,000 position at the $0.93 low returned $17,634 profit (+176.6%) at the high. The open-to-close trade from $1.45 to $2.33 returned $6,069 (+60.7%). Both were profitable, which is what happens when the catalyst is real.

AKAN — +378.3% MFE, Closed +223.1%

AKAN traded 45.9M shares on April 22, running from a $3.25 low to a $12.33 high — a +378.3% MFE. It closed at $10.50 (+223.1%) and continued to $13.65 after hours. The specific catalyst was not identified in available press releases, but the 6-K filing on April 29 and the adjourned special meeting of shareholders suggest corporate action was driving institutional interest.

HTCO — +360.1% MFE, Closed +192.3%

HTCO exploded on April 27 with 14.3M shares traded. It opened at $13.00, hit $56.59, and closed at $38.00 (+192.3%). The full-day MFE from the $12.50 low to the $56.59 high was +360.1%. After-hours faded to $29.00. The specific catalyst was not identified in available press releases — which makes this a higher-risk name. It ran hard but without a verifiable "why," chasing after the first move was gambling, not trading.

Last Week's Losers (Apr 20-24): What Went Wrong

Showing only winners is dishonest. Here are the names that trapped traders last week — and what the watchlist framework would have flagged.

CHSN — The -92.7% Collapse

CHSN is the cautionary tale of the week. On April 24, it opened at $2.50, briefly hit $3.00, then cratered to $0.16 before closing at $0.18 — a -92.7% market close. It faded further to $0.14 after hours. Volume was enormous at 147.0M shares.

The MFE from the absolute low ($0.16) to the high ($3.00) was technically +2,207.7% on paper — but that number is misleading. The high came first and the low came after. For anyone who entered near the open at $2.50, the actual experience was watching their position lose 93% of its value in a single session.

What the framework would have caught: No press release or catalyst news was identified for CHSN. No verified catalyst. A name moving on volume alone with no identifiable reason is the highest-risk setup in penny stocks. The watchlist filter — does this ticker have a catalyst? — would have kept it off the list entirely.

XTLB — +103.8% MFE but Closed -6.1%

XTLB traded 114.0M shares on April 29 at 4,616x its average daily volume. The full-day range was $2.39 to $4.87 — a +103.8% MFE. But it closed at $3.54, down -6.1% from its $3.77 open.

The catalyst was real: XTL Biopharmaceuticals announced it would acquire Psyga Bio to establish a psychedelic biotechnology platform with clinical pipeline and GMP manufacturing (6-K filing, April 29). So why did it close red despite a legitimate catalyst?

This is the dilution layer at work. When a biotech announces an acquisition, the first question a research-backed trader asks is: how are they paying for it? If the answer involves share issuance, the acquisition catalyst is simultaneously a dilution event. The stock runs on the headline, then fades as the market prices in the share impact.

A $10,000 position capturing the full MFE from $2.39 to $4.87 would have returned $10,377 (+103.8%). But the open-to-close trade lost $610 (-6.1%). Timing was everything — and knowing the dilution risk context would have told you to take profits fast.

SCNI — +191.3% MFE but Closed -5.6%

SCNI traded 200.8M shares on April 24 at 4,192x RVOL. PM high was $1.30, market open was $0.80, and the stock bounced between $0.66 and $1.05 before closing at $0.75 (-5.6%). Full-day MFE from the $0.45 low to the $1.30 PM high was +191.3%.

The catalyst: Scinai Immunotherapeutics announced a $2.61M private placement financing. Here's the lesson — a private placement is simultaneously a catalyst AND dilution. The stock runs on the capital raise headline ("they have cash now") but fades as the market realizes new shares are hitting the float. SCNI is a textbook example of why understanding dilution mechanics is non-negotiable for penny stock traders.

ATER — +175.0% MFE but Closed Only +1.8%

ATER was the highest-volume name of the week: 257.5M shares at 5,941x RVOL on April 28. The full-day range was $0.68 to $1.87 for a +175.0% MFE. But it opened at $1.10 and closed at $1.12 — just +1.8%.

The catalyst: Aterian announced a definitive agreement for the sale of its marquee brand portfolio for $18M. The irony: this is a company selling its core assets. The market initially spiked on the headline ("$18M deal!") but quickly realized this was a liquidation event, not a growth catalyst. The stock round-tripped almost entirely.

A $10,000 position at the $0.68 low to the $1.87 high returned $17,500 (+175.0%). The open-to-close trade returned just $182 (+1.8%). The MFE was there — but only for traders who recognized this was a news-spike-and-fade pattern and took profits aggressively within the first 30 minutes.

The SEC Filing Layer: 32 Offering Filings in 3 Days

Any watchlist built without checking the SEC filing pipeline is incomplete. In the past 3 days alone, the platform tracked significant registration and offering activity that directly impacts tradability.

This is the dilution pipeline in real time. If PAVM shows up on your scanner with a volume spike, and you check the SEC research tool and see a fresh 424B3 filing, you know shares are being unlocked for resale. That doesn't mean you can't trade it — but it means you trade it as a scalp, not a swing. The exit plan changes entirely.

For deeper context on how each filing type impacts price action, see our SEC filings breakdown for traders.

Entry and Exit Framework: How to Trade What the Watchlist Finds

The framework below is educational — not financial advice. It's the structure a research-backed approach follows once a ticker passes all three watchlist layers.

Pre-market screening (7:00-9:25 AM):

• Scan for tickers with abnormal PM volume and price movement. Last week, ATER showed a $1.23 PM high before opening at $1.10. YAAS had a $1.59 PM high before its $1.45 open. Both signaled institutional interest before the bell.
• Cross-reference every PM mover against the news feed. Does it have a press release? A filing? If yes, it stays on the watchlist. If no — like CHSN — it gets flagged as high-risk.

Entry zones:

• First pullback after the opening spike. SKLZ opened at $3.62, dipped to $3.25, then ran to $20.00. That $3.25 dip was the entry.
• VWAP reclaim. If a stock gaps up, pulls below VWAP, and reclaims it with volume, that's a higher-probability entry than chasing the gap.

Exit management:

• With catalyst: Hold for larger move but trail stops. YAAS held because the acquisition catalyst was real. SKLZ faded from $20.00 to $12.44 to $8.81 AH — trailing a stop at HOD minus 20% would have captured $14-16 on a $3.25 entry.
• Without catalyst: Scalp only. ATER round-tripped from $1.87 back to $1.12. No catalyst = take profit fast.
• With dilution filing: Scalp the initial spike, exit before the dilution hits. SCNI's private placement and XTLB's acquisition-via-shares both faded into close. The first 15-30 minutes were profitable; holding through was not.

Risk management:

• Position sizing: 2-5% of account per trade on penny stocks. These names can lose 90%+ in a single session (see CHSN).
• Hard stop: Below the session low or the PM low, whichever is lower. If SKLZ broke below $3.25, the thesis was dead.

How to Set Up This Scan on SNACS

The SNACS scanner surfaces these setups in real time. Here's the exact filter configuration to replicate this week's watchlist approach.

Step 1: Volume filter Set minimum volume to 10M shares and RVOL to 5x minimum. This immediately filters the 2,500+ ticker stream down to the handful showing unusual institutional-level activity. This week, that filter would have caught ATER (5,941x), XTLB (4,616x), SCNI (4,192x), and YAAS (3,288x) within minutes of their moves starting.

Step 2: Price range Set the price filter to $0.50-$20. This keeps you in the penny stock and small-cap range where these patterns occur most frequently.

Step 3: Catalyst check via Ticker Detail Click any ticker in the scanner to open the detail popover. This gives you the chart, recent news with AI headline summaries, SEC filings, and the dilution risk panel — all without leaving the scanner. If the ticker turns blue in the stream, that means news just broke. This is how you would have caught SKLZ's jury verdict headline or YAAS's acquisition announcement in real time.

Step 4: Dilution filter In the scanner, check the Dilution Alerts column. Any ticker showing an active ATM, shelf, or recent 424B filing gets flagged. You can also open the full SEC research dilution snapshot for a complete breakdown: active facility counts, shares at risk, lowest exercise price, and the DVS risk score.

Step 5: Save the scan as a Dynamic Watchlist Once your filters are set, save the scan as a named preset. Then link it to a Dynamic Watchlist — the scan results auto-populate in real time. Matched tickers show a colored square in the main scanner stream, so you'll see them the instant they trigger.

Step 6: Set up playbook alerts If you use the Playbook Builder, create a setup for your preferred entry pattern. When a ticker on your watchlist matches the pattern, a star indicator appears in the scanner. You can also set email or in-app alerts with cooldown settings so you're not glued to the screen.

Last Week's Macro Context

Tech/AI dominated the news cycle last week with 88 articles — IBM launching AI and quantum hubs, Meta hiking AI spending forecasts, and continued semiconductor momentum. Oil/Energy saw 16 articles including Marathon Petroleum's dividend announcement and BP's Venezuela offshore deal. China trade showed 7 articles with Qualcomm soaring 16% on CEO comments about China orders.

For penny stock traders, the macro context matters less for individual setups and more for sector rotation. When AI dominates headlines, biotech and tech-adjacent penny stocks tend to see more speculative volume — which is exactly what happened with XTLB's psychedelic biotech acquisition catalyst.

What to Watch Next Week

The filing pipeline is loaded. Five new S-3 shelf registrations (SLNH, NVFY, SNSE, LFWD, VOR) were filed in the past 3 days, which means these companies now have the ability to sell shares at any time. Any volume spike on these names in the coming weeks should be immediately cross-referenced against new 424B5 prospectus supplements — that's the signal that the offering is actually happening.

Three S-1/A amendments (IMG, FCUV, FUSE) suggest those registration statements are responding to SEC comments and moving toward effectiveness. When an S-1/A goes effective, it often triggers a volume spike as the market prices in the new shares.

Keep your scanner filters tight: 5x RVOL minimum, $0.50-$20 price range, and always — always — check the catalyst and dilution layers before entering. The 95 patterns this week produced both +515% winners and -93% losers. The research framework is what separates the two.

Track every trade in a structured journal — noting whether you checked all three layers before entry and whether you managed the exit according to your plan. That feedback loop is what turns a watchlist into edge.

FAQ

What is MFE and why does it matter for penny stock watchlists?

MFE (Max Favorable Excursion) measures the best possible trade from a stock's session low to its session high. A stock can close red but still have offered +100% or more MFE for a day trader who timed the entry and exit. This week, XTLB closed -6.1% but had a +103.8% MFE, and SCNI closed -5.6% with a +191.3% MFE. MFE tells you the real opportunity — not just the closing print.

How do I tell the difference between a real penny stock catalyst and a pump?

Real catalysts have verifiable sources: press releases on Business Wire or Globe Newswire, SEC filings on EDGAR, or FDA announcements. This week, SKLZ had a verifiable jury verdict press release and ran +515.4% MFE. CHSN had no identifiable catalyst and collapsed -92.7%. Always cross-reference the news feed in the SNACS ticker detail popover before entering.

How many stocks should be on a daily penny stock watchlist?

A focused watchlist of 5-10 names is more effective than watching 50. Last week produced 95 scanner pattern detections, but only a handful had the catalyst + volume + clean dilution profile that makes a real setup. Filtering aggressively is the skill — not finding more tickers, but eliminating the ones that don't meet all three criteria.

Why do some penny stocks spike then immediately fade?

Often the catalyst is simultaneously bullish AND dilutive. SCNI announced a $2.61M private placement — which meant cash coming in (bullish headline) but also new shares hitting the float (dilutive reality). The stock spiked on the headline, then faded as the dilution impact was priced in. Checking active dilution facilities before entry changes your trade plan from hold to scalp.

What RVOL level signals a meaningful penny stock move?

RVOL (Relative Volume) above 5x the 50-day average is the threshold for unusual activity. Last week's biggest moves all exceeded 3,000x RVOL — ATER at 5,941x, XTLB at 4,616x, SCNI at 4,192x, and YAAS at 3,288x. Set your scanner minimum to 5x to filter noise, then sort descending to see the most extreme spikes first.

How do SEC filings affect penny stock watchlists?

SEC filings are the single most important non-price signal for penny stocks. In the past 3 days, 16 424B5 prospectus supplements were filed across 14 tickers — meaning those companies are actively pricing and selling shares. A stock on your watchlist with a fresh 424B5 should be traded as a quick scalp, not a multi-day hold. The SNACS scanner shows dilution alerts in a dedicated column.

What is a liquidity test pattern in penny stocks?

A liquidity test is when price sweeps a key level — a prior support, a round number, or a VWAP zone — to test supply and demand before the real move. Market makers or insiders probe these levels to gauge how many shares are available at specific prices. This week saw 54 liquidity test patterns detected across the scanner, making it the most common pattern type.

How do I track whether my watchlist process is working?

Use a structured trading journal that logs whether you checked all three layers (volume, catalyst, dilution) before each entry, and whether you followed your exit plan. The SNACS trading journal auto-syncs from 8 brokers and includes AI Insights that analyze your patterns over time — identifying your best setups, worst times of day, and MFE capture rate.
