Semiconductor supplies to Huawei have been targeted by Washington as part of the broader U.S.-China trade war.

Evercore analysts expect another leg down in the memory chip market in the fourth quarter of 2019 and now see the industry's recovery pushed to the second half of next year.

As a result, they said they are becoming more selective in the chip sector and slashed price targets on some stocks.

The analysts said a reason for their negative view is they see continued excess inventories in both DRAM and NAND memory. NAND storage is a primary storage, which is commonly used in such things as cellphones and USB flash drives. DRAM memory is different in that it used to allow computers, phones and tablets to run multiple applications at the same time, but it is not primary storage.

They said they see the most near-term downside risk for Western Digital, Micron and Lam Research. All of those stocks were down more than 4% in morning trading. The analysts said they prefer ASML and Applied Materials.

Other analysts have been more positive and see the industry turning the corner sooner.

The Evercore analysts sliced price targets for Applied Materials, KLA Tencor and Teradyne. They are maintaining Applied Materials' rating at outperform, but the price target was lowered to $50 from $55. KLA Tencor is also rated inline, but the price target was pared to $120 from $130. Meanwhile, Evercore's price target for Teradyne went from $47 to $43.

Lam Research was downgraded to inline, and the analysts cut its price target to $195 from $225.

"While we reduced our estimates 2 weeks ago for [Micron], worse trends since then causes one more cut— we are better buyers in high $20's. For [Western Digital], we maintain Underperform rating and $30 PT. We see ongoing excess inventories weighing on NAND pricing through CY19," they wrote.

Also weighing on chip stocks is the risk from Huawei, which the U.S. government is banning from using U.S. suppliers.
