Now would be a great time for Apple (AAPL) CEO Tim Cook to tweet that the iPhone X has had a strong holiday season. 

Shares of the tech giant slid 2.5% to $170.57 on Tuesday on growing fears of cooling iPhone X demand. Sinolink Securities said in a new report Monday that iPhone X shipments in the first quarter may be a whopping 10 million below their prior estimate. It marked the third report in under a week to cite the iPhone X's $1,000 price tag as stunting consumer demand.

One report in particular should bring fear to Apple bulls. According to a Dec. 24 report from Economic Daily News, Apple may see 30 million units of the iPhone X sold in the first quarter compared to a previous forecast of 50 million.

The speculation on how the iPhone has fared quickly spread to Apple supplier stocks on Tuesday. Prices below are as of 11:15 a.m. EST.

  • Lumentum Holdings (LITE) -5.8% (3D sensor supplier)
  • Cirrus Logic (CRUS) -1.6% (audio chip maker)
  • Skyworks Solutions (SWKS) -1.9% (radio frequency semiconductor supplier)
  • Finisar Corporation (FNSR) -4.3% (chip maker that just landed a $390 million investment from Apple)
  • Broadcom Limited (AVGO) -1.6% (radio-frequency, Wi-Fi and wireless charging chip supplier)
