Branch inventory reconstruction
Accumulating holders Branches that accumulated shares during the window and still hold positive inventory; they are the absorbing side.
Distributing sellers Branches that built inventory earlier and have been selling it down; the remaining number estimates what has not cleared.
Net-short desks Trading-desk branches with negative inventory or net selling, often hedge, offsetting, or short-term flow. It is not automatically a bearish view.

Historical evidence

Valuation regime and subsequent returns

Each day's PE is converted to its own-history percentile (as of that day), then we look at adjusted-close returns over the next 240 trading days by valuation regime.

PE percentile bandSample days240-day avg returnMedianWin rateAvg excess (vs index)
0-20 67+265.2% +262.5% 100% +219.2%
20-40 109+58.8% +68% 85.3% +31.8%

80-100 You are here59+23.1% +22.3% 89.8% -4%

Percentiles use an expanding own-history window (no look-ahead); forward return is 240 trading days on adjusted close. Sample days overlap; distribution is indicative only.

Current PE ≈ 89.2, at the 90.5th percentile of its own history (80-100 band).

Valuation × momentum historical grid

Every day in its own history is bucketed by valuation tercile (own-history PE) and 60-day momentum sign into six cells; we show adjusted-close returns over the next 120 trading days per cell.

What does 科風 do? Company profile

其他電子業;不斷電系統(UPS)與電力保護設備 上市(台灣證券交易所)

Overview

3043 對應證券為科風,為台灣證券交易所上市普通股。公司成立於1987年4月24日,總部位於新北市中和區連城路246號9樓,主要經營不斷電電源供應器。Yahoo奇摩股市基本資料顯示掛牌日期為2002年8月26日,股本為新台幣389,756,340元,已發行普通股38,975,634股;產業類別為其他電子。董事長資料來源有差異:Yahoo奇摩股市列示董事長與總經理皆為楊淑艷;玩股網與公開董監資料則列示董事長為科飛投資股份有限公司、總經理為楊淑艷,推測楊淑艷為法人董事長代表人。主要內部人/董監持股依公開資訊整理包含楊淑艷384,968股、韓榮裕237,886股、科飛投資股份有限公司105,409股、玖業投資股份有限公司103,600股、蔡念澎1,200股等;董監持股比例整體偏低。公司官網與法人簡報稱科風成立於台灣,為台灣 UPS 不斷電系統品牌,於台灣及廣東設置工廠,並通過 ISO9001、ISO14001。

Business

科風核心業務為 UPS 不斷電系統及電力保護相關產品之研發、製造與銷售,採自有品牌 POWERCOM 與 OEM/ODM 並行。產品線包含在線式 UPS、在線互動式 UPS、離線式 UPS、三相在線式 UPS、機架式 UPS、監控軟體、AVR 穩壓器、自動轉換開關、其他電源配件,並曾涉足太陽能逆變器與太陽能電廠整合服務。MoneyDJ資料顯示2024年產品營收比重中不斷電系統約占99%;Treelazy彙整之114年度年報資料顯示2025年產品組合為 UPS 840,215千元、占98.37%,其他13,909千元、占1.63%,顯示營收高度集中於 UPS。主要原料包含電池、PCB素材、機殼鐵件、微處理器、變壓器等。銷售以外銷為主,透過代理商、通路商及系統廠合作銷往亞洲、歐洲、美洲等市場;終端應用包括電腦、通訊、醫療、精密設備、資料中心、伺服器、再生能源與工業電源等需穩定供電或備援電力之場景。2025年公司營收854,124千元,較2024年882,491千元減少3.21%;2025年稅後淨損105,073千元,較2024年稅後淨利36,307千元大幅轉弱,主要需觀察本業費用、業外收支與匯率影響。2026年前5月合併營收353,486千元,年減12.8%,其中5月單月營收69,452千元、年增3.74%。

Outlook 2025–2028

2025至2028年展望可分為需求動能、產品升級與風險三部分。需求面:資料中心、AI伺服器、邊緣運算、通訊基礎建設、醫療與再生能源設備對穩定供電與備援電力需求提高,對 UPS 與相關電力保護設備具中長期支撐。MoneyDJ 2024年底報導指出,公司看好伺服器、再生能源帶動 UPS 需求,並表示正在著手 BBU 產品;BBU採鋰電池與直流供電,科風既有鋰電池產品與超級電容經驗,使其具備技術切入可能,但實際訂單、認證與量產貢獻尚未公開確認。產品面:114年度年報揭露115年度經營方針包括開發高功率密度、高轉換效率綠能電源產品,研發鋰鐵電池應用方案,提供長壽命且具數據分析能力的電力保障設備;同時深化全球大型通路商合作、針對各國電網環境提供解決方案、推動零件平台化與標準化以降低庫存風險,並策略性縮減低毛利大宗產品、提升高獲利產品比重。2026至2028年若 AI 資料中心與再生能源備援需求延續,公司有機會由傳統 UPS 往高階 UPS、鋰電/鋰鐵電池方案、BBU與工業電源擴張。風險面:公司規模小、營收高度集中 UPS,2025年已出現虧損,2026年前5月累計營收仍年減;若大客戶需求波動、海外通路去庫存、匯率波動、低價中國 UPS 競爭、原物料價格與電池供應成本上升、安規認證或BBU新產品開發不順,將壓抑毛利與營收復甦。2027至2028具體財務預測公司未公開,以上為依公開法說、年報與產業趨勢之推估。

Method and limitations

  • All returns use adjusted close (etl:adj_close), already adjusted for dividends and splits.
  • Excess return is measured against the TAIEX total-return index (dividends included).
  • Valuation regime and percentile stats use an expanding own-history window (no future data).
  • Revenue-signal event dates align to the first trading day after the filing deadline, avoiding look-ahead.
  • Event samples may overlap in time; stats describe historical distribution only and are less reliable when samples are few.
