How The Streak Compares With The Market
Over the same 8 trading days, the S&P 500 returned 0.0% including dividends, so the slide is mostly Amkor Technology’s own story rather than the market’s. Over the past three months the stock is down 28.7%, a window that includes the streak; over the other 55 sessions of that window it was down 10.9%.
Do The Fundamentals Justify The Selling?
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 20.0 times trailing earnings against a median of 35.7. The selling is hard to square with the fundamentals: revenue growth above the median and a multiple below the median.
