First, the honest part: shorting is the hardest thing a swing trader does
Long and short are not symmetric, even within the same swing-trading style.
One: time is not on your side. Over the long run indices drift upward — inflation, earnings growth, steady inflows. Going long is swimming with the current; get the timing wrong and holding often bails you out. Shorting is swimming against it, and the longer you hold the harder it gets.
Two: the downside isn't capped the same way. The worst case on a long is zero — you lose 100%. A short has no ceiling. A stock going from 50 to 150 costs you 200%. That isn't a scare story; short squeezes really do double a name in a few days.
Three: declines are faster than advances. That cuts both ways. When you're right you're paid quickly; when you're wrong there's no time to think it over.
Four: the mechanics get in the way. Margin shorting requires collateral, a shortfall in the maintenance ratio triggers a call, positions must be covered ahead of shareholder meetings and ex-dividend dates, and regulators can restrict short selling during severe volatility. These rules change — confirm the current numbers with your broker before you trade.
So this isn't an argument for shorting. It's for doing it with better odds if you've already decided to.
The only edge: go with the trend
The most common way to die shorting is to short something because it "has run too far" or is "too expensive."
Expensive is not a reason. A stock can stay expensive for a long time, and it can double again from the point where you were sure it had gone far enough. The market doesn't turn because you think it should.
There is one rule: wait until the trend is already down, then join it.
Don't forecast the turn. Don't guess the top. Wait for bearish alignment to form — for the market to tell you through price that this thing is falling — and then enter. You're being paid for trend continuation, not for foresight.
What bearish alignment is, and why it works
When 5MA < 10MA < 20MA < 60MA, the moving averages are in bearish alignment.
Read it through "a group's average cost" and it becomes obvious: the earlier someone bought, the higher their cost and the deeper their loss. A steadily falling price stacks layer upon layer of trapped holders overhead. Every bounce brings them out looking to get even — and that is where the pressure comes from.
Put another way, bearish alignment tells you that the selling pressure above is real, not imagined.
In the screener, set "05 MA alignment" to strict bearish (5MA < 10MA < 20MA < 60MA). For a looser filter, loose bearish (5MA < 10MA < 20MA) leaves the 60-day line out, which catches names earlier in a decline.
Entry one: short into the squeeze of converging averages
When all four averages converge within 5%, buyers from every timeframe hold roughly the same cost. There's no direction; the market is stuck.
That state doesn't last. Once it resolves, the move that follows is usually decisive — so positioning during the squeeze captures the largest move.
The cost is plain: you're betting on a direction that hasn't shown itself yet. A squeeze is about as likely to break up as down. Half the time you'll be standing directly in front of the trend.
In the screener, MA convergence (all four within 5%) finds these names.
When it makes sense: when you have some reason beyond the chart — deteriorating revenue, a sector cycle rolling over, a weak overall market. Shorting a squeeze on the chart alone is a coin flip.
Entry two: after a long black candle breaks down, wait for the small green bounce
This is the higher-probability version.
The sequence:
- Find stocks with converging averages and put them on your watchlist
- Wait for a long black candle that breaks through the cluster of averages — that's direction confirming itself
- Do not chase on the breakdown day
- Wait for the small green candle on the bounce, and short there
Steps three and four are the hard part. Most people can't do them.
Why the bounce candle matters
On the breakdown day, fear peaks and price often overshoots. Chase there and you frequently get a technical bounce right in your face.
Waiting for the small green candle buys you three things:
A better price. Your entry sits higher, which is simply room to be wrong.
Trapped supply on your side. Everyone who bought inside that long black candle was underwater the same day. When price bounces back toward their cost, they want out at breakeven. Short there and a crowd of people wants to sell alongside you.
Consensus already formed. A long black breakdown is visible to everyone reading a chart. After it, the market's view of the stock has turned — you are not the only one waiting to short the bounce. Consensus becomes self-fulfilling.
The cost: you give up the breakdown day's move, and sometimes there is no bounce at all — it just keeps falling and you never get on.
This is the trade-off between hit rate and payoff. The first method pays more and works less often; the second works more often and pays less. Neither is better. It depends on your temperament and how many consecutive losses your capital can absorb.
When you're right, sit still
The biggest gains in shorting don't come from a perfect entry. They come from holding when you're right.
If the position does turn into a sustained decline — alignment stays bearish, each bounce fails below the last high, the 5MA keeps capping price — let it run. A simple rule like "cover if it closes back above the 10-day line" protects the gain far better than taking 5% and leaving.
Swing-trading returns are lumpy: most trades are small wins and small losses, and a handful are large. Cut every trade short and those few large ones never happen.
Running it in the screener
Finding candidates (after each close)
- 01 Universe: top 300 by market cap — enough liquidity that you're less likely to be squeezed
- 05 MA alignment: strict bearish or loose bearish for declines already underway, or MA convergence for names about to show their hand
- 03 MA condition + 04 Direction: choose below, matched to your holding period (10-day for shorter trades, 20-day for swings)
Narrowing down
If the screen returns too many names, look at the sector distribution. Bearish alignment clustered in one industry usually means the whole sector is rolling over — more worth shorting than a single weak stock. Setting monthly revenue YoY to a negative bracket filters out names whose fundamentals are still holding up.
Check the market first
Open the Market Barometer and read the overall environment. Shorting individual names while the index is in bullish alignment means fighting two currents. The best time to be short is when the index itself is in bearish alignment.
Last thing
My honest view on shorting: you don't have to learn it.
Plenty of swing traders go long only for an entire career and do no worse for it. The value of shorting isn't an extra way to make money — it's having something to do in a decline, so you don't force bad long trades out of boredom.
If you do want to learn it, start with a very small position, and find out whether you can sit through "right on direction, but squeezed 10% first." There's no way to know that without having done it.
