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)
0-20 351+11.1% +9.6% 85.2% +6.9%

80-100 You are here369+22.3% +19.5% 64.2% -8.5%

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 ≈ 60.0, at the 88.3th 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.

優盛集團分為醫療器材事業群與零售/連鎖藥妝通路事業群。2025年合併營收為新台幣3,799,559千元,年減1.34%;合併毛利1,306,206千元;合併稅後淨損68,594千元。依2025年年報部門別營收,醫療器械為577,756千元、占15.21%,零售部門為3,221,803千元、占84.79%。主要產品包括電子血壓計、血糖/血氧/溫度量測產品、呼吸治療產品、霧化器、抽痰機、體重/體脂相關產品,並搭配 Rossmax Healthstyle App、健康小站與雲端照護平台發展數位健康服務。商業模式上,醫材事業包含自有品牌 ROSSMAX 與部分 OEM/ODM/Private Label;通路事業則透過佑全藥品旗下佑全保健藥妝、健康人生藥局、札幌藥妝等實體門市、電商與機構送藥服務銷售藥品、保健品、醫材、日用品與長照相關產品。2025年主要銷售區域為台灣內銷3,284,029千元、占86.43%;歐洲136,027千元、占3.58%;美洲35,757千元、占0.94%;其他外銷343,746千元、占9.05%;外銷合計13.57%。公司2025年醫材事業營收約5.78億元,依年報引用2025生技產業白皮書所列台灣醫療器材營業額估算,約占台灣醫材市場0.38%。2025年底連鎖藥妝直營與加盟門市合計171家;富果法說整理則指出2025年第三季門市172家,其中佑全保健藥妝141家、健康人生15家、札幌藥妝16家。公司近兩年度無單一銷貨客戶占銷貨總額10%以上,年報以A1、A2等匿名揭露;主要進貨廠商也無單一供應商占進貨總額10%以上。

Outlook 2025–2028

2025至2028年展望以營運改善與數位健康/連鎖通路擴張為核心,但短期仍有獲利壓力。成長動能包括:1. 高齡化、慢性病增加與個人健康管理需求提升,推動居家量測、遠距監測、穿戴式/連網醫材與健康資料平台需求。2. 優盛在血壓、血氧、血糖、溫度、體重等多參數量測硬體上導入藍牙、APP與PARR心律不整偵測功能,並以 Rossmax Healthstyle App、健康小站、優活雲等軟體提高附加價值。3. 新產品方向包含居家心電圖、血液量測產品、長時間持續量測醫材與耗材、持續性血糖監測、脈衝式霧化器、進階血氧/動脈彈性測試、兒童照護與銀髮照護系列。4. 通路事業方面,佑全藥品在台灣連鎖藥局連鎖化率提升、高齡照護、處方箋與長照藥事服務、線上線下整合、日系美妝與電商業務上有擴張空間;2026年規劃完成二代自動倉儲與GDP倉,有助於藥品採購、庫存管理、機構送藥與B2B配送效率。5. 公司策略為整合醫材硬體、藥局通路與照護軟體,形成居家保健與社區照護平台。主要風險與挑戰包括:後疫情時代醫材需求回歸常態,疫情期間庫存去化拖累需求;2024至2025年已連續虧損,零售部門裁撤績效不佳門市與費用控管仍需時間反映;血壓計等成熟產品面臨歐姆龍、百略、陸資低價品牌及本地品牌競爭;歐盟MDR及各國醫材法規、臨床驗證、資安與數位醫療合規門檻提高;原物料、匯率、關稅與地緣政治可能影響毛利與外銷;連鎖藥局展店面臨租金、藥師薪資、庫存與同業競爭壓力。2027至2028年具體財務指引未見公司公開預測,本段長期展望屬依年報策略、法說摘要與產業趨勢推估。

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.
