20 Stocks. Zero Winners. That’s When Everything Changed.
In 2021, I did something that every penny stock believer eventually does. I went all in on the dream.
I bought shares in 20 different penny stock companies. Not 20 trades in the same stock, 20 separate companies. One position in each. I spread my capital across biotech startups, cannabis plays, EV shell companies, crypto mining stocks, and a handful of names I can’t even remember anymore because they’ve since been delisted.
My thesis was simple: penny stocks were going parabolic everywhere I looked. Every day, my scanner showed some random ticker up 500%, 800%, 1,000% in a matter of hours. Twitter was full of screenshots, guys turning $2,000 into $40,000 on a single trade. The math felt obvious. If I just owned enough of these stocks, one of them would hit and cover all the others.
I was wrong about all 20.
By the end of 2021, every single position was in the red. Not some of them. All of them. Some were down 50%. Some were down 80%. A few were down over 95%. One did a reverse split and then dropped another 70% after that. I wrote about what I learned from those losses in detail, the dilution, the shady CEOs, the fake press releases, the reverse split cycle designed to drain retail accounts.
But here’s the part of the story I haven’t told yet.
Those losses didn’t just teach me what not to buy. They taught me what to short.
The Flip: Why Penny Stocks Are Better Shorted Than Bought
When you buy a penny stock, you’re betting on hope. You’re betting that this company, the one with $200K in revenue and a CEO who’s run three other stocks into the ground, is somehow going to defy the odds and become a real business. The base rate on that bet is terrible. Most penny stocks lose 70%+ of their value within a year. Many go to zero.
But when you short a penny stock, you’re betting on gravity. You’re betting that the stock that just ran 400% on a press release about a “strategic partnership” with a company nobody’s heard of is going to come back to earth. And gravity, in the penny stock world, is the most reliable force there is.
After losing on all 20 of my long positions, I decided to learn short selling. I studied the mechanics. I opened an account with a broker that offered short locates, first Webull for practice, then Cobra Trading for real execution. I put in hundreds of hours of screen time watching penny stocks pump and dump, studying the patterns, learning the rhythm.
And what I discovered was this: the same patterns that destroyed me as a long investor became profitable setups as a short seller. The dilution, the offerings, the fake news pumps, all of it was predictable. I just had to be on the right side of the trade.
But, and this is the part that most people skip, shorting penny stocks is not easy money. It’s some of the most dangerous trading you can do. A stock that’s up 200% can go up another 300% before it comes down. If you’re short and wrong, the losses are theoretically unlimited.
So before you ever short a penny stock, you need to check five things. I learned each of these the hard way.
1. Float: The Single Most Important Number You’ll Ever Check
Before I short any penny stock, the first thing I look at is the float, the number of shares available for public trading.
This is the number that will save your account or blow it up. Nothing else comes close.
Here’s why float matters more than anything else: supply and demand. A penny stock with a 1 million share float trading at $2 per share has a total tradeable market cap of $2 million. That’s nothing. There are individual traders with $2 million portfolios. If just two or three of them decide to buy a few hundred thousand dollars worth of shares, they’ve just absorbed a massive percentage of the available supply.
When demand exceeds supply on a low-float stock, price doesn’t just go up. It squeezes. And when it squeezes, short sellers get destroyed.
I’ve seen low-float penny stocks go from $2 to $20 in a single session, not because the company was worth anything, but because there weren’t enough shares to go around and shorts were forced to cover at any price. That’s a 900% move against your position. If you shorted $10,000 worth of stock, you now owe $90,000. In a single day.
My rule: I don’t short any penny stock with a float under 5 million shares unless I have exceptional conviction and tiny position size. The lower the float, the higher the squeeze risk. Period. A stock with a 50 million share float is far less likely to squeeze because there’s enough supply to absorb buying pressure without price going parabolic.
Check the float before you check anything else. If the float is too low, walk away. No setup is worth getting squeezed on.
2. Volume: When Everyone’s Rushing In, Don’t Stand in Front of the Train
Volume tells you how many participants are in the game, and on day one of a penny stock run, you can’t tell whose side they’re on.
When a penny stock suddenly prints 50 million shares of volume, compared to its normal 500,000, something has changed. New players have entered. Algorithms are firing. Social media is buzzing. The stock is “in play.”
Here’s the problem with shorting into that kind of volume on day one: you don’t know who’s holding overnight. Are those 50 million shares mostly bought by longs who plan to hold for a multi-day run? Or are they mostly day traders who will sell before the close? You can’t tell. And that uncertainty is a massive risk for a short seller.
If the volume is dominated by longs holding overnight, the stock can gap up 50-100% the next morning, and your short position is underwater before you even sit down at your desk.
My rule: I rarely short a penny stock on day one of a massive volume surge. I watch. I let the first day play out. I study the Level 2 and the tape after hours. I look at where the stock closes relative to its high. I check whether the volume profile suggests distribution (selling into strength) or accumulation (buying on dips).
Day two and day three are typically where short setups become safer, volume starts declining, the initial excitement fades, and the stock begins to follow gravity. But day one? Day one is a battlefield where you can’t see who’s on which side. Stay out of the crossfire.
3. Sector Heat: Don’t Short the Trend, Short the Stragglers
In 2020 and 2021, Bitcoin went on one of the most explosive runs in financial history. And every penny stock even remotely connected to crypto went with it.
Stocks like BTBT, MARA, and RIOT, small-cap crypto mining companies, gained hundreds of percent in weeks. Not because they were great businesses. Not because their fundamentals justified the move. But because the sector was on fire and money was flowing into anything with “blockchain” or “mining” in the company description.
If you tried to short those names during peak sector heat, you got destroyed. I know because I watched it happen to traders around me. They were “right” about the fundamentals, these companies were overvalued by any rational measure, but the sector momentum didn’t care about fundamentals. When an entire sector is running, rational analysis takes a backseat to crowd psychology.
My rule: When a sector is hot, crypto, AI, cannabis, EV, biotech, I don’t short the leaders. I don’t short the names that are running with the sector. Instead, I wait for the sector to cool, and then I short the stragglers, the stocks that ran with the group but have no real business to sustain the move once the hype fades.
The leaders might hold their gains because they have actual revenue, actual products, actual institutional backing. The stragglers, the ones that were just riding the wave, collapse the fastest when the tide goes out. Those are the shorts that pay.
Read the sector. Respect the momentum. And never stand in front of a freight train because your indicators say it should stop.
4. Indicators Don’t Work on Penny Stocks, Stop Relying on Them
This one is going to be controversial, and I don’t care.
Traditional technical indicators like RSI and VWAP do not work reliably on penny stocks. I’m not saying they’re useless tools, they’re excellent on large-cap stocks with deep liquidity and consistent participation. I use them every day on names like Tesla, NVIDIA, and SPY. But on penny stocks? They’ll get you killed.
Here’s why: indicators like RSI are designed to measure momentum relative to historical norms. RSI of 70 means “overbought”, the stock has moved too far, too fast, and a pullback is likely. That works on Apple because Apple has institutional flows, options activity, and algorithmic rebalancing that create mean-reversion behavior.
A penny stock doesn’t have any of that. A penny stock with an RSI of 95 can stay at RSI 95 for three more days while the stock triples. I’ve seen it. I’ve traded against it. And I’ve lost money because I thought the indicator was telling me the truth.
The same applies to VWAP. On a large-cap stock, VWAP acts as a magnet, price tends to revert to VWAP throughout the session because institutional algorithms are buying and selling relative to that benchmark. On a penny stock with 2 million shares of float and no institutional participation, VWAP is just a line on a chart. Nobody is trading relative to it. It has no gravitational pull.
My rule: On penny stocks, I rely on price action, volume, and the tape, not indicators. I watch how the stock trades at key price levels. I watch whether sellers are hitting bids or buyers are lifting asks. I read the Level 2 order flow for signs of exhaustion or distribution. These are real-time signals from actual market participants, not mathematical formulas derived from historical data that doesn’t apply.
If you want to understand how RSI and VWAP work on stocks where they actually matter, large-cap, liquid names, read our full guides on RSI and VWAP. They’re excellent tools in the right context. Penny stocks just aren’t that context.
5. Not All News Is Created Equal, Learn to Read the Catalyst
Every penny stock pump starts with a headline. But not every headline carries the same weight, and understanding the difference is the edge that separates profitable short sellers from the ones who get squeezed into oblivion.
Here’s the framework I use:
High-Squeeze Risk News (Don’t Short Into These)
FDA approvals or positive clinical trial results for biotech/pharma companies. When a small biotech announces that the FDA has approved its drug or that a Phase 2 trial showed positive results, the move can be massive and sustained. These catalysts represent a genuine fundamental change in the company’s value, the drug might actually generate revenue. Shorting into legitimate FDA catalysts is one of the fastest ways to blow up an account.
Acquisition or buyout offers. If a larger company makes a bid to acquire a penny stock, the price locks near the acquisition price. Shorting a stock with a pending buyout is financial suicide.
Legitimate contract wins with named, verifiable partners. If a penny stock announces a $50 million contract with a Fortune 500 company, and you can verify it on the Fortune 500 company’s filings, that’s real news. The stock may sustain its move.
Lower-Squeeze Risk News (Potential Short Setups)
Nasdaq minimum bid compliance. A stock announcing it has “regained compliance with Nasdaq listing requirements” sounds positive but means almost nothing. It just means the stock got back above $1, usually after a reverse split. This is cosmetic, not fundamental. These pumps tend to fade.
Vague “strategic partnerships” with unnamed or unverifiable partners. If the press release doesn’t name the partner, or names a company you can’t find on Google, the news is likely promotional fluff designed to pump the stock for an upcoming offering.
“LOI signed” or “MOU entered into.” Letters of intent and memorandums of understanding are non-binding. They’re the corporate equivalent of “we should grab coffee sometime.” Until a definitive agreement is signed with financial terms disclosed, these announcements carry minimal fundamental weight.
Paid promotional campaigns. If a penny stock is suddenly appearing in email newsletters, StockTwits spam accounts, and paid YouTube ads, the pump is manufactured. These campaigns are funded, often by insiders or affiliates holding shares, specifically to create liquidity for a sell. The stock runs on retail excitement, then collapses when the promotion ends and the offering drops.
My rule: Before I short any penny stock, I read the actual news, not the headline, not the StockTwits reaction, the actual filing or press release. I assess whether the catalyst represents a genuine change in the company’s business or a promotional event designed to create a selling opportunity. If it’s the latter, the short setup is on.
The Rules of Engagement: How I Short Penny Stocks Now
After years of refinement, here’s my process:
Check the float first. If it’s under 5 million, the position size gets cut to a fraction of normal, or I pass entirely.
Never short day one. I let the first-day fireworks play out and look for exhaustion signals on day two or three.
Read the sector. If the sector is running, I wait for the cooldown. I short the weakest names in the group, not the leaders.
Ignore indicators. I trade the tape, the volume, and the order flow, not RSI, not VWAP, not moving averages.
Grade the news. Real catalysts with fundamental impact get respect. Promotional fluff gets shorted.
Use the right broker. You can’t short penny stocks on Robinhood. You need a broker with short locate access, I use Cobra Trading for locates and DAS Trader Pro for execution. Webull works for easier-to-borrow names if you’re starting out.
Size small. My penny stock short positions are always smaller than my large-cap positions. The volatility is 10x higher, so the position size has to be 10x smaller. Risk management isn’t optional, it’s the only thing standing between you and a blown account.
The Bottom Line
I lost money on every single penny stock I bought in 2021. Twenty companies. Zero winners. That experience burned the lesson into me permanently: the deck is stacked against long-side penny stock investors.
But those same stocks, the ones with dilution cycles, promotional pumps, and inevitable collapses, became the setups that taught me how to short. The patterns that destroyed my long portfolio became the patterns that rebuilt my trading career from the other side.
Short selling penny stocks is not a beginner strategy. It requires screen time, discipline, and a deep understanding of the risks, especially squeeze risk. If you’re new, start by watching. Paper trade. Study the five checkpoints in this article. And when you’re ready, when you’ve put in the hours and you understand what you’re looking at, take your first small short with a broker that gives you the tools to execute it properly.
The game isn’t rigged against you. You just have to stop playing the side that’s designed to lose.
