The Standard & Poor’s 500 index fell about 4.6% from its recent peak of 7,620 points to about 7,265 points, and this decline has pushed dozens of large companies into what traders call oversold territory.
When a stock declines hard enough and fast enough, technical indicators begin to indicate that the selling may have gone too far, and learning to read those signals can help you separate the temporary decline from the real decline.
What are oversold stocks?
Oversold stocks are stocks that have fallen so sharply over a short period that technical indicators indicate that selling pressure is extended and there may be a short-term bounce.
The most common metric is the relative strength index, or RSI, which is a measure of momentum that ranges from 0 to 100 A reading below 30 indicates that the stock is in the oversold zone.
Oversold describes price momentum, not business value, so a stock can be oversold and still be a poor investment, just as a high-quality company can trade at an oversold reading for entirely temporary reasons.
How does the RSI indicate oversold conditions?
The standard Relative Strength Index compares a stock’s average gains with its average losses over the past 14 trading sessions.
When losses dominate that window, the reading drops toward 30 or lower, indicating that sellers were in almost complete control.
The flip side is the Relative Strength Index (RSI) above 70, indicating that the stock is overbought and possibly due for a pullback.
You can see the indicator in action now: Trimble held its RSI at 25.85 on June 11, making it the most sold name in the S&P 500 during the current market segment, Benzinga’s latest screen found Trade consumer stocks like Alibaba with RSI readings near or below 30.
The Relative Strength Index (RSI) is one of many momentum tools, and many traders pair it with it Other day trading indicators Such as moving averages or stochastics to confirm what they see.
Why do stocks become oversold?
The most common trigger is bad news that arrives suddenly, such as an earnings miss, guidance cut, analyst downgrade, or regulatory headline.
Broad-based market declines are also important, because selling across the index drags down fundamentally sound companies along with weak ones, which is exactly what happened during the recent S&P 500 decline.
Forced selling adds fuel, as margin calls, clawbacks, and end-of-quarter rebalancing can push prices below the level where willing buyers and sellers might meet.
Selling due to the December tax loss and panic during sharp corrections have the same effect, pushing prices beyond the point justified by fundamental news.
Does oversold mean you should buy?
Not automatically, and this is the mistake that costs new traders the most money.
An oversold reading indicates that the selling has been intense, not that it has ended, and the stock could remain in a strong downtrend below the RSI of 30 for weeks as the decline continues.
Traders call this “catching the falling knife,” and the way to avoid it is to assert yourself.
Many are waiting for the RSI to rise back above 30 before making its move, as this crossover indicates that buyers are actually stepping in rather than just hoping.
Others look for bullish divergence, which appears when the price makes a new low but the RSI makes a higher low, indicating that downward momentum is fading.
Pair the RSI with a second signal, e.g MACD indicator next to RSIHelps filter out false lows.
It’s also worth checking the fundamentals, because an oversold stock that has steady revenues and a manageable balance sheet is a different bet than an oversold stock that’s at risk of bankruptcy.
How to find and trade oversold stocks
Most stock screeners allow you to filter for a Relative Strength Index (RSI) below 30, then narrow the list by market cap, trading volume, or sector.
Adding a minimum daily volume, such as 50,000 shares, weeds out thinly traded names where they could potentially create a price gap against you.
From there, charting software does the heavy lifting, and… The TradeStation platform includes the Relative Strength Index (RSI) and dozens of other built-in momentum indicators You can place a layer on any chart, along with scanning tools that indicate oversold names in real time.
Whatever platform you use, size trades small and set a stop loss before entering, because mean bounce trades fail often enough that one uncontrolled loss can wipe out many gains.
With the S&P 500 still well below its peak in June, oversold screens are unusually crowded right now, making the next few weeks a useful live test: See if names like Trimble see their RSI rise back above 30, since that rebound, not the low reading itself, is the signal that disciplined traders have been waiting for.
