RE:CeillingAgreed that this sector is overvalued, but less downside risk compared to the bigger names that have jumped significantly. I'd revisit the P/E after the next earnings (January 2018). This will be the biggest quarter to date as it is inclusive of sales from the P2 expansion for the entire quarter, as opposed to the 2 weeks from the previous quarter. Keep in mind P2 took annual capacity from 2600 kg to 8000 kg.
Personally, I even think that there's plenty of upside in the short term. With all the cash APH is sitting on, I'm sure we are just one news release away from new all time highs.
