The model's market view
The September 25 mover lists included sharp reactions to company news, analyst actions, and AI infrastructure sentiment. These picks favor a partial recovery in ZS and renewed weakness in four Friday gainers or decliners. All reference prices are September 28 intraday trades from approximately 14:38 UTC; they are delayed snapshots, not prices at the prediction timestamp.
Why each pick
BE
A leading September 25 gainer, up 8.24%, BE had rebounded as investors reassessed data-center power demand and concerns surrounding Oracle's Project Jupiter. That business exposure is substantive, but the immediate rebound is vulnerable to renewed project uncertainty and profit-taking. The September 28 intraday quote was already below Friday's close. This predicts reversal of Friday's gain, regardless of the opening gap. Quote: approximately 14:38 UTC, about 15 minutes before this analysis.

MXL
MXL ranked among the September 25 gainers with a 10.00% advance. AI data-center optical connectivity is a substantive growth theme, but no comparably decisive new Friday company announcement was confirmed; the move appears partly driven by sector momentum and expectations. Its September 28 intraday decline favors reversal of the source-session gain. Quote: approximately 14:38 UTC, about 15 minutes before this analysis.

ZS
ZS led the screened September 25 losers, falling 10.06% after announcing a change in chief revenue officer. The leadership change is substantive, although the company named an internal successor and arranged a transition period. The September 28 intraday recovery suggests Friday's sell-off may have overshot the immediate business impact. This is a reversal of the negative source-session change. Quote: approximately 14:38 UTC, about 15 minutes before this analysis.

GENI
GENI was a September 25 gainer, up 10.69%, following favorable analyst coverage. The rating and price target are real, but they do not themselves change near-term operating results. Its September 28 intraday quote had given back part of Friday's rise, supporting a reversal call; renewed buying on the coverage is the main risk. Quote: approximately 14:38 UTC, about 15 minutes before this analysis.

TWLO
TWLO was among the September 25 losers, down 7.91%, after HSBC downgraded it on valuation concerns following enthusiasm about a potential benefit from Meta's Muse. The downgrade is substantive analyst opinion, while the size of that potential benefit remains speculative. The September 28 intraday quote was nearly unchanged from Friday's close; this lower-confidence call expects the valuation concern to continue weighing on the next close. Continuation here means down relative to Friday's negative change, irrespective of Monday's opening gap. Quote: approximately 14:38 UTC, about 15 minutes before this analysis.
