NEW YORK (TheStreet) -- It was solar inverter company Advanced Energy Industries (AEIS) turn to take a beating from investors on behalf of the solar inverter market, which has been hit hard in the past two weeks.
Advanced Energy Industries shares were down more than 10% in the early afternoon on Wednesday and trading was above the full day average volume.
The solar inverter market took a tumble last week after the world's largest inverter maker, Germany's SMA Solar, provided a cautious outlook about 2011. Power-One (PWER) was the big loser in the bunch, down 25% in the past week before a comeback today after it announced a share buyback program.
(MKSI), downgraded by Bank of America from buy to sell. MKS Instruments shares were down by more than 8%, less than AEIS's 10% decline, even though the Bank of America call was less negative on AEIS shares.
