Teradyne Is Down 27% in 3 Days. Is the Bottom Near?

Teradyne Is Down 27% in Just 3 Days. Is This a Buying Opportunity?

Teradyne, Inc. (TER) has shifted from the green zone to the yellow zone as of April 30, 2026, following a rapid price correction that erased more than a quarter of its market value in less than a week. The stock is currently trading at $306.33, representing a -26.7% drawdown from its all-time high of $418.08. This sudden move has triggered a significant change in the Drawdown Severity Score™, which now sits at 4.2.

Breaking Down the 4.2 Drawdown Severity Score™

The transition from the green zone to the yellow zone indicates that the current sell-off has moved beyond a routine fluctuation. Our data shows that Teradyne (TER) has spent only 3 days in this specific drawdown cycle, yet the velocity of the decline is what has pushed the Drawdown Severity Score™ into the "Significant" category. While the stock has faced 91 total historical drawdown events, the current -26.7% decline is already more than double the company's average max drawdown of -10.6%.

The Drawdown Severity Score™ of 4.2 serves as a quantitative measure of how unusual this price action is compared to the stock's entire trading history. In a typical cycle, Teradyne (TER) experiences an average drawdown duration of 159 days. The fact that the stock has reached a -26.7% decline in just 3 days suggests an institutional-level repricing rather than a slow drift lower. We monitor these zones because a shift into the yellow zone often precedes a period of heightened volatility as the market attempts to find a new floor.

Historical Context: When Teradyne Drops This Far

To understand the potential path forward, we must look at how the stock has behaved during previous periods of extreme stress. Our data indicates that Teradyne (TER) has dropped by 70% or more exactly 4 times in its history. While the current -26.7% drop is not yet at that extreme level, the historical precedent for major recoveries is lengthy.

For those 4 historical instances where the drawdown reached the 70% threshold, the average duration of the drop and subsequent recovery was 2819 days. It is important to note that this is a small sample size of only 4 events, which can skew averages significantly. However, these figures highlight that when Teradyne (TER) enters a deep correction, the path to a new all-time high can be measured in years rather than months.

Assessing the Velocity of the Current Decline

The current drawdown of -26.7% is particularly striking because of its brevity. Most historical declines for Teradyne (TER) take much longer to materialize. By reaching a 4.2 Drawdown Severity Score™ in only 3 days, the stock is exhibiting a "crash" profile rather than a standard "correction" profile.

When we analyze the 91 historical drawdown events in our database, we see a pattern of cyclicality. The semiconductor testing equipment sector, where Teradyne (TER) operates, is notoriously sensitive to capital expenditure cycles. A move of this magnitude often suggests that the market is pricing in a fundamental shift in demand or a broader macroeconomic headwind that impacts the entire industry.

What to Watch for in the Yellow Zone

The yellow zone represents a crossroads for investors. A Drawdown Severity Score™ of 4.2 means the stock is no longer in a "buy the dip" environment characterized by low-risk entries. Instead, it has entered a phase where the data suggests the risk of further downside is mathematically higher than it was a week ago.

We will be watching for two specific data shifts. First, we look for a stabilization of the price that allows the Drawdown Severity Score™ to plateau or decrease. Second, we monitor the "Days in Drawdown" metric. If the stock remains at these levels without further decline, the time element of the drawdown will eventually start to weigh on the severity score, either confirming a new base or signaling a deeper move toward the red zone.

The Data Picture: Visualizing the Recovery Path

Looking at the current price of $306.33 against the all-time high of $418.08, the stock requires a significant rally just to return to its previous peak. Our proprietary data suggests that investors should focus on the duration of past recoveries. With an average drawdown duration of 159 days across all 91 events, history suggests that patience is usually required before a stock in the yellow zone returns to the green zone.

Because the current decline happened in just 3 days, it is an outlier. Outliers in the Drawdown Severity Score™ often lead to one of two outcomes: a "V-shaped" snapback if the selling was overdone, or a prolonged period of consolidation if the fundamental outlook for the company has changed. Our data currently leans toward the latter given the severity of the initial move.

Factors That Could Shift the Severity Score

Several factors could influence whether Teradyne (TER) stays in the yellow zone or moves deeper into significant drawdown territory. Monitoring the broader semiconductor sector and peer companies like ASML Holding (ASML) or KLA Corporation (KLAC) can provide context on whether this is a company-specific issue or a sector-wide re-rating.

We also look for the "comparableCount" to change. If the stock continues to fall, it will move into a tier of historical drawdowns that have even fewer precedents, making the price action even more unique. For now, the 4.2 Drawdown Severity Score™ remains the primary metric for gauging the current risk profile of the stock. We will continue to track these numbers as the drawdown progresses.
