There are 5 names up for grabs this week though the IPO markets have increasingly been under the scrutiny of Wall Street now that the economy is looking less than consistent. Valuations and sales continue to be a focus going forward.

The largest offering of the week is out of Brazil. StoneCo (STNE  ) is a cloud based, online payment processor with $289 million in sales for the last 12 months. The company has attracted the attention of Warren Buffets company which plans to buy just over half of the offering. They will offer 47 million shares at a range of $21 - $23 in hopes of raising $1.05 billion.

YETI Holdings (YETI  ) will once again try to launch their IPO. The company which sells high end, premium branded coolers and other outdoor items did try to launch back in 2016 but had to postpone until now. They will offer 20 million shares at a range of $19 -$21 in hopes of raising $400 million. The company has $737 million in sales over the last 12 months but has considerable debt and marketing expenses.

Alberton Acquisition (ALACU  ) is a blank check company based in Hong Kong which is hoping to raise $100 million to acquire other companies. These types of IPO's are very likely to be heavily scrutinized during this volatile market.

There are two biotech names up this week. The first is Gamida Cell (GMDA  ) which is a late stage hematologic malignancy therapy company looking for $50 million. They will offer 3.5 million shares at a range of $13 -$15 to get through phase 3 of their trials. The other name is Alzheon (ALZH  ) which is also a Phase 3 company focused on Alzheimer's. They will offer 2.5 million shares at a range of $13 - $15 in hopes of raising $35 million.
