# RIG, FCEL, and ZS: 3 Stocks Making Outsized Moves Today

Broader indexes are facing renewed headwinds today as **semiconductor weakness** weighs on tech sentiment. A trio of names is drawing trader attention this afternoon: offshore driller **Transocean Ltd. (NYSE:RIG)**, clean-power play **FuelCell Energy Inc. (NASDAQ:FCEL)**, and cloud-security stalwart **Zscaler Inc. (NASDAQ:ZS)**. Below, we dig into what is moving the shares of RIG, FCEL, and ZS.

* * *

## RIG Tags 2-Year High Amid Hedge Fund Interest

Transocean shares are up 7% to trade at $7.54, earlier hitting a two-year high of $7.56 after on Friday Elliott Management disclosed a new position in Transocean in its Q1 2026 13-F filing. On the analyst side, Barclays upgraded RIG from "equal-weight" to "overweight" on May 7. The stock has been grinding higher over recent weeks, pushing from the mid-$5s as a string of higher lows signals steady dip-buying support.

## FCEL Cools Off

FCEL is down 19.2% to trade at $17.24, likely pulling back after **sector peer NextEra** Energy (NEE) made its move for Dominion (D). FCEL hit a two-year high of $22.83 on May 15 and is up 135% in 2026.

## ZS Shrugs Off Bear Notes

ZS is up 7.7% to trade at $173.58 today, shrugging off two price-target cuts to $225 and $210 at B. Riley and Mizuho, respectively. ZS is down 23% in 2026 still, but has cleared its 100-day trendline today for the first time since November.
