PSIX makes engines and packaged power systems, including the gensets data centers buy for backup and prime power, and is majority-owned by China's Weichai. The stock collapsed 74% from its February high to $25.28 on July 29, then reclaimed 63% in seven sessions. The last leg was a +21% gap on Friday, off Thursday evening's Q2 print: revenue $152.5M against a $134M estimate, gross margin up 420bps sequentially to 27.1%, $30.8M of debt paid down in one quarter SEC EDGAR 8-K · Aug 2026. Set against that: a 7.3M-share float with 23.9% of it sold short, and a chart still below its 200-day average. This is a momentum-and-squeeze trade with defined risk, not a quality compounder. Our five-lens value board votes 4/5 bearish at this price.

The beat streak broke in 2026: two straight EPS misses. But the consensus here is one or two analysts, and Friday's tape graded the revenue line (+14% vs estimate), not the EPS line. Read this table with that asterisk. — Next: 5 November 2026 Yahoo Finance — Analysis · live

The structure is a broken downtrend attempting a V: 52-week high $121.78 (August 2025), February high near $99, then a five-month slide to $25.28 on July 29. The reversal came in two gaps, +6.0% on August 4 and +21.3% on Friday, neither filled. Price at $41 sits 26.2% above the 20-day EMA ($32.58), above the 50-day ($37.33), and well below the 200-day ($53.82). Friday's intraday range ran $38.28-$42.03, with the June range high at $43.23 the last shelf before the air pocket the May collapse left behind: there is little traded volume between $43 and the mid-$50s. ATR is ~$3 and the August 21 straddle prices a ±15% move. Size for that, not for a normal industrial.
The risk is not dilution or solvency; both check out clean. It is buying a 2-beta, 100%-IV controlled company 26% above its 20-day average, the morning after a print the (very thin) consensus scored as an EPS miss. The invalidation levels don't cover the calendar either: at beta 2.1, the 10-15 session window crosses mid-August macro (CPI, Jackson Hole), and a risk-off tape can hand this name a stop-out day with zero PSIX news. The half-size guidance is there for that too, not just the float.
Q2 showed real operational repair (a 14% revenue beat, 420bps of sequential gross-margin gain, $30.8M of debt retired) into a 7.3M-share float carrying 24% short interest positioned during the slide to $25. Above $43.23 there is almost no traded supply until the mid-$50s. Friday's 21% gap says buyers were grading the revenue and margin lines, whatever the EPS headline scored. Tactical long at half size, 10-15 sessions.
