# Weekly Recap | Q/C Tech -13.81%, gains faded after collaboration news

## The Week

Q/C Tech (QCLS) fell 13.81% this week to $0.748. The S&P 500 slipped 0.27% over the same stretch, leaving the stock roughly 13.5 percentage points behind. The week was marked by an intraday spike and give-back: Monday opened at $0.8322, Tuesday closed higher at $0.8933, and Wednesday hit the week’s high of $1.04 before fading to $0.8511. Thursday and Friday sold off, with Friday ending at the weekly low. The week’s amplitude was 36.04%. Daily volume averaged about 2.03m shares, far above the 193.6k median, with Wednesday churning 7.81m shares in a single session.

## Key Events

The one substantive company story this week landed on Wednesday. On 30 September at midday, Q/C Technologies announced a research collaboration with Sandia National Laboratories, a $5 billion U.S. Department of Energy lab. Later the same day, a ‘ghost tickers’ report surfaced pointing to nine U.S. stocks falling out of regulatory view, and QCLS was among the names listed. On the filings front, a 4/A issuer update appeared on 3 October. The timing is easy to see: the collaboration news broke on Wednesday, the stock spiked to $1.04 intraday, and then gave back all of that move over the next two sessions.

## The Week Ahead

No company earnings are scheduled after Friday’s close. The calendar is dominated by U.S. macro data: services PMI final data and ISM non-manufacturing PMI on 5 October, followed by trade balance figures on 6 October and EIA crude inventories on 7 October. For a small-cap name like QCLS, these readings shape broad risk appetite more than the company’s fundamentals. Watch for any follow-up details on the Sandia collaboration in the coming days.

## In Short

The valuation remains depressed, with a PB of roughly 0.38x and a negative PE. The latest session’s flows show net selling across medium and small order buckets, with large orders absent. The week produced a real collaboration announcement, but the stock weakened after the news, and the tape was thin and volatile. The open question is whether the Sandia tie-up turns into visible order flow or revenue, and whether macro sentiment keeps pressuring mid-to-tail names like this one.
