# Weekly Recap | GCDT.US +25%, AI cooling news drives sharp swings

## The Week

Green Circle Decarbonize Tech rose 25% this week to close at $0.50 on Friday, versus $0.40 at the previous Friday’s close. The S&P 500 gained 1.15%, so the stock outperformed by roughly 23.85 percentage points. The week followed a spike-then-fade pattern: Monday opened at $0.4004 and closed at $0.4291; Wednesday hit an intraday high of $1.095 before sliding to $0.7270; Thursday closed at $0.5663; Friday fell further to $0.50. Weekly amplitude reached 175.7%, and average daily volume of around 2.3m shares was about 9.3x the 60-day median of 222k shares.

## Key Events

The main story this week was the company’s announced entry into AI data-centre cooling. On Tuesday, Green Circle Decarbonize Technology said it planned to enter the AI data-centre cooling market with proprietary ultra-low energy liquid cooling solutions. On the same day, the company filed a 424B3 and an EFFECT notice appeared. Trading turned volatile mid-week: Wednesday dipped 7.09% pre-market, then closed down 27.82% as the market reacted to execution risk around the AI pivot and an SEC warning. The stock fell another 24.36% on Thursday and 13.16% on Friday. From the filings, the two material items this week were the 424B3 and EFFECT, both on Tuesday.

## The Week Ahead

A dense run of US macro data is due next week: NFIB Small Business Optimism Index and existing home sales on Tuesday, followed by CPI and core CPI on Wednesday. CPI has a prior reading of 3.4% against a 3.7% forecast, while core CPI has a prior of 2.4% against a 2.5% forecast. The company has no disclosed major events next week, but market digestion of the AI liquid cooling announcement may continue, with execution updates and regulatory signals worth watching.

## In Short

GCDT.US had a high-volatility week, rising 25% on the AI data-centre cooling announcement while intraday price pulled back from $1.095 to $0.50. On valuation, P/B stands at 0.16x and P/E at -0.67x, with earnings still negative. In the latest trading session, medium-lot and small-lot flows were net positive, while large-lot flows showed no clear direction. The tension is between a new business direction and high price swings, with profitability not yet in place. The key follow-through is whether the AI liquid cooling business translates into actual orders or revenue, and how macro data shapes overall risk appetite.
