Amkor Technology Stock Extends A 10-Day Losing Streak To A 25% Loss
Shares of Amkor Technology (AMKR) have closed lower in each of the last 10 sessions, a cumulative decline of 25.3%. That erased about $3.5 billion from the company's market value, which now stands at about $10.4 billion. The stock closed at $41.82 on Friday, October 16, 55.2% below its 52-week high of $93.38 and 39.5% above its low of $29.98.
The Streak Next To The S&P 500
Returns for AMKR and the S&P 500 over the streak and the periods around it, all ending Friday, October 16 and including dividends:
| Return Period | AMKR | S&P 500 |
|---|---|---|
| 1 Day | -5.1% | -1.1% |
| 10 Days (Current Streak) | -25.3% | -0.8% |
| 1 Month (21 Trading Days) | -12.8% | 0.4% |
| 3 Months (63 Trading Days) | -33.0% | 3.2% |
| Year To Date | 6.4% | 12.9% |
| 1 Year (252 Trading Days) | 34.6% | 16.2% |
How The Streak Compares With The Market
The market explains little of this: the S&P 500 lost 0.8% over the same 10 sessions, including dividends, against Amkor Technology's -25.3%. Over the past three months the stock is down 33.0%, a window that includes the streak; over the other 53 sessions of that window it was down 10.3%.
What The Numbers Say About The Slide
On the fundamentals, revenue grew 17.9% over the last twelve months, against a median of 17.9% for S&P 500 Information Technology stocks; its operating margin is 8.6%, versus a median of 21.6%; and the stock trades at 18.7 times trailing earnings against a median of 34.0. On these numbers the business looks sturdier than the stock, with revenue growth above the median and a multiple below the median.
If the drop has you weighing an entry, resist buying on price alone. Our Buy the Dip screen ranks the marked-down names where growth and cash generation still hold up.
A Slide Like This Is Why Diversification Exists
Watching one stock fall day after day is the clearest lesson the market teaches about single-name risk. Whether this particular decline is an opportunity or a warning, the deeper point is the same: no one name should be able to do this to your portfolio.
The Trefis High Quality (HQ) Portfolio is built on that principle: roughly 30 businesses selected for consistent cash generation, strong margins, and resilient balance sheets, sized and rebalanced with rules. It has a track record of outpacing a benchmark that combines the S&P 500, the S&P MidCap 400, and the Russell 2000. Study the slide; spread the risk.
