I have traded in an out... bot again last week. Divvy is great, valuation is low, memory is in high demand, SSDs will not displace HDD in the data center for a long time. The HDD insustry has consolidated down to 2 players... a disciplined duopoly is good for pricing. OTOH, the PC business is hurting and smaller mobile devices do not use HDD, but use SSD/and or flash.
I've traded in and out of STX also. Not currently holding any right now.
I don't think the business of hard drives is threatened in the short term by the declining PC. I still prefer my PC over mobile device. Not that PC's are STX main driver.
The divi is good for a tech stock. Technically, I'd prefer to see a pull back to just above $25 before buying again.... for a retest of that price. If you buy under $26, play it with a stop just under $25. I think it's worth a risk, but there are better stocks in my view.
