US Stock Screener: Screening the S&P 500 with Relative Strength, Stage 2 & VCP美股篩選完整指南：從台灣與香港鎖定美股主流強勢股
What Is a US Stock Screener?
A US stock screener scans the American market — roughly 5,700 listed stocks across the NYSE and NASDAQ — and narrows it to a manageable list that matches your criteria. A momentum US screener goes further: it surfaces the names that are actually leading the market, ranked by relative strength and confirmed by trend and base structure.
The US is the deepest, most liquid equity market in the world, and it sets the tone for global sector leadership — semiconductors, software, AI infrastructure and biotech leaders usually appear in the US tape first. That is exactly why a disciplined US screen is valuable not just to American traders but to investors in Japan, Taiwan and Hong Kong who want exposure to those global leaders.
什麼是美股篩選工具？
美股篩選工具掃描美國市場——橫跨 NYSE 與 NASDAQ 約 5,700 支上市股票——將其縮小為符合你條件的可管理清單。動能型美股篩選工具更進一步：它篩選出真正領漲市場的股票，依相對強度排名，並以趨勢與底部結構加以確認。
美國是全球最深、流動性最強的股票市場，為全球類股領導權定調——半導體、軟體、AI 基礎設施與生技領域的主流強勢股，通常最先出現在美股市場。正因如此，嚴謹的美股篩選對美國交易者固然重要，對於希望參與這些全球主流股的日本、台灣與香港投資人而言，同樣極具價值。
Why Screen US Stocks from Asia (Japan, Taiwan & Hong Kong)
If you trade primarily TSE, TWSE or HKEX names, adding a US screen to your routine does three things:
- Access to global leadership. The biggest secular trends — AI, cloud, semiconductors — are led by US-listed companies. Screening the US is how you find those leaders early, in the same methodology you already use at home.
- A read on risk appetite. US breadth and leadership are a barometer for the whole world. When US momentum is broad and healthy, Asian markets usually have a tailwind; when it narrows, that is a warning that travels.
- Diversification by time zone and currency. US positions trade while Asia sleeps and settle in USD — a natural complement to a home-market book.
The methodology does not change when you cross the Pacific. A stock breaking out of a tight base on rising relative strength behaves the same in New York as it does in Tokyo or Taipei — only the ticker and the trading calendar differ. See the full momentum-screening pillar guide →
為何要從亞洲篩選美股（日本、台灣與香港）
如果你主要交易 TSE、TWSE 或 HKEX 的股票，在日常功課中加入美股篩選，能帶來三大好處：
- 觸及全球領導力。 最大的長期結構性趨勢——AI、雲端、半導體——均由美國上市公司領導。篩選美股，正是你用早已熟悉的方法論，提早發現這些主流股的途徑。
- 解讀風險偏好。 美股市場寬度與領漲格局，是全球的晴雨表。當美股動能廣泛而健康時，亞洲市場通常享有順風；當動能收窄，這個警訊也會隨之傳遍全球。
- 時區與貨幣分散。 美股在亞洲睡眠時段交易，以美元結算——是本國投資組合的天然補充。
方法論過了太平洋不會改變。一支股票在 RS 持續上升的背景下從緊湊底部突破，在紐約、東京或台北的行為模式完全相同——唯一改變的只是代號與交易日曆。查看動能選股總指南 →
The US Universe: S&P 500 vs. the Full Market
The first decision in any US screen is how wide to look:
| Universe | Size | Best for |
|---|---|---|
| **S&P 500** | ~500 | Higher liquidity, institutional-quality names, fewer false positives |
| **Full US market** | ~5,700 | Catching smaller, faster-moving leaders earlier (more noise) |
Most investors start with the S&P 500 as a focused, liquid universe — it filters out illiquid microcaps where momentum signals are unreliable — then widen to the full market once they want to hunt earlier-stage leaders. AlpharvestPro lets you screen either: the focused S&P 500 set or the broader universe, with the same momentum criteria applied to both.
美股選股範疇：S&P 500 vs. 整體市場
美股篩選的第一個決策是：篩選範圍要多廣？
| 選股範疇 | 規模 | 最適用途 |
|---|---|---|
| **S&P 500** | 約 500 支 | 流動性較高，法人等級股票，假突破較少 |
| **美國整體市場** | 約 5,700 支 | 提早發掘規模較小、動能更強的主流股（雜訊較多） |
多數投資人從 S&P 500 開始——作為聚焦且流動性高的選股範疇，可過濾掉動能觀察不可靠的低流動性微型股——待想要尋找更早期階段的主流股時，再擴展至整體市場。AlpharvestPro 讓你可以二選一：以聚焦的 S&P 500 集合，或以更廣泛的市場為範疇，並對兩者套用相同的動能篩選條件。
Screening US Stocks with Relative Strength, Stage 2 & VCP
The same three-layer methodology that works on any market is the backbone of a good US screen:
| Layer | What it does on the US tape | Deep-dive guide |
|---|---|---|
| **RS Rating** | Ranks each US stock 1–99 vs. the whole market — keep RS ≥ 70 | Relative strength |
| **Stage 2 / Trend Template** | Confirms a real uptrend (price > rising MA50 > MA150 > MA200) | Minervini stage analysis |
| **VCP base** | Flags tightening bases setting up for a breakout | VCP pattern detection |
In the US specifically, RS is doubly useful: with 5,700 names, you need a hard ranking to cut the field fast, and US sector leadership rotates quickly (e.g., semis → software → industrials). Watching which US sectors hold the most RS-strong leaders is often an early tell. See heatmaps & sector rotation →
以相對強度、第二階段與 VCP 篩選美股
適用於任何市場的三層方法論，是優質美股篩選的核心骨幹：
| 篩選層次 | 在美股市場的作用 | 深度指南 |
|---|---|---|
| **RS 評級** | 將每支美股依相對整體市場排名 1–99——保留 RS ≥ 70 | 相對強度 |
| **第二階段／趨勢範本** | 確認真實上升趨勢（股價 > 上升中的 MA50 > MA150 > MA200） | 米奈爾維尼階段分析 |
| **VCP 底部** | 標記正在收縮、蓄勢突破的底部型態 | VCP 型態偵測 |
在美股市場，RS 評級的作用加倍顯著：面對 5,700 支股票，你需要明確的排名來快速縮小選股範圍，而且美國的類股領導權輪動迅速（例如：半導體→軟體→工業）。觀察哪些美國類股集中了最多 RS 強勢的主流股，往往是提早示警的線索。查看熱力圖與類股輪動 →
How AlpharvestPro Screens the US Market
Our US pipeline runs the same disciplined process every US trading day:
- Build the universe — load the full NYSE/NASDAQ list (~5,700 names), with the S&P 500 marked as a focused subset.
- Rank by relative strength — compute an RS Rating for every US stock and keep the leaders (RS ≥ 70). This is the biggest cut.
- Apply the Stage 2 trend template — keep only confirmed uptrends (above rising MA50/150/200, proper MA stacking, sane distance from the 52-week high).
- Detect bases and patterns — run the VCP engine and OWL pattern detection to flag US stocks tightening into a base or showing accumulation.
- Check US market breadth — read the % of US stocks above MA50/MA200 to judge whether the overall environment supports new entries.
The result is a short, ranked list of US candidates for research — never a "buy list." Every name still needs your own chart and risk work. See today's US candidates →
AlpharvestPro 如何篩選美國市場
我們的美股資料管道在每個美國交易日執行相同的嚴謹流程：
- 建立選股範疇 — 載入完整的 NYSE/NASDAQ 清單（約 5,700 支），並將 S&P 500 標記為聚焦子集。
- 依相對強度排名 — 計算每支美股的 RS 評級，保留主流強勢股（RS ≥ 70）。這是篩選力道最大的一關。
- 套用第二階段趨勢範本 — 僅保留確認上升趨勢的股票（站在上升中的 MA50/150/200 上方、均線多頭排列、距 52 週高點距離適中）。
- 偵測底部與型態 — 執行 VCP 引擎及 OWL 多方交易警示偵測，標記正在收縮進入底部或顯示籌碼堆積跡象的美股。
- 確認美股市場寬度 — 讀取站在 MA50/MA200 上方的美股比例，判斷整體環境是否支持新進場。
結果是一份簡短的美股研究候選名單——絕非「買進清單」。每支候選股仍需你自行完成圖表分析與風險管控。查看今日美股候選標的 →
Practical Notes for Asia-Based US Investors
- Timing works in your favor. The US closes at 4:00 p.m. ET — that is early morning in Asia. AlpharvestPro re-runs the US screen after the close, so a fresh US candidate list is waiting in your Asia morning, before your home market opens.
- Charts. US tickers link out to Finviz (`finviz.com/quote.ashx?t=TICKER`) and TradingView (`NASDAQ:` / `NYSE:` symbols) — no zero-padding, unlike HK codes.
- Currency. US positions are priced in USD; factor FX into position sizing. (This is an observation, not advice.)
- You can research before you can trade. Screening US stocks is research and needs no brokerage — most Japanese, Taiwanese and Hong Kong brokers offer US-market access when you are ready to act.
亞洲美股投資人的實務備忘
- 時間優勢站在你這邊。 美股收盤時間為美國東部時間下午 4 點——對亞洲投資人來說，正好是清晨。AlpharvestPro 在美股收盤後重新執行篩選，因此在你的亞洲早晨、本國市場開盤之前，最新的美股候選清單便已就緒。
- 圖表連結。 美股代號連結至 Finviz（`finviz.com/quote.ashx?t=TICKER`）與 TradingView（`NASDAQ:` / `NYSE:` 格式）——不需像港股代號一樣補零。
- 匯率。 美股以美元計價；在計算部位大小時，請將外匯因素納入考量。（此為觀察性說明，非投資建議。）
- 交易前就能開始研究。 美股篩選是研究工作，不需要開設券商帳戶——等你準備好行動時，多數日本、台灣與香港券商均提供美股市場的交易管道。
Common Mistakes Screening US Stocks
- Screening the full 5,700 with no liquidity floor — momentum signals on thin microcaps are unreliable. Start with the S&P 500 or apply a volume/price floor.
- Ignoring relative strength — a US stock up on the day can still lag the index. Anchor on RS, not the day's move.
- Buying extended leaders — the strongest US names are often the most extended. Wait for a proper base. See the Stage 2 conservative filter →
- Screening against the market — even the best US setup fails when US breadth is negative. Check breadth first. Market breadth guide →
- Treating a screen as a buy list — a screener produces *candidates*. The chart, the risk and the entry are still your decisions.
美股篩選的常見失誤
- 未設定流動性門檻便篩選全部 5,700 支股票 — 低流動性微型股的動能觀察不可靠。從 S&P 500 開始，或設定成交量／股價下限。
- 忽視相對強度 — 美股當日上漲，仍可能是市場的落後者。以 RS 作為錨點，而非當天的漲幅。
- 追買已過度延伸的主流股 — 最強的美股往往也是延伸最遠的。等待合適的底部型態。查看第二階段保守篩選條件 →
- 逆市場環境選股 — 即便是最佳的美股設置，當美股市場寬度轉負時也會失敗。先確認市場寬度。市場寬度指南 →
- 將篩選結果視為買進清單 — 選股工具篩出的是*候選標的*。圖表、風險與進場判斷，仍是你自己的決策。

FAQ
Can I screen US stocks from Japan, Taiwan or Hong Kong?
Yes. AlpharvestPro screens the full US market (NYSE/NASDAQ) every US trading day and publishes the leaders in a timezone that lands in the Asian morning. You can research US candidates with no brokerage; you only need US-market access when you decide to trade.
Should I screen the S&P 500 or the whole US market?
Start with the S&P 500 — it is liquid and filters out unreliable microcaps. Widen to the full ~5,700-name universe when you want to catch smaller, earlier-stage leaders and are comfortable with more noise.
What is the best way to screen US stocks for momentum?
Rank the universe by relative strength (keep RS ≥ 70), confirm a Stage 2 uptrend, and look for a tight VCP base near a pivot — then check that overall US breadth is supportive. That stack is what separates real leaders from stocks that are merely up on the day.
When does the US screener update for Asian time zones?
AlpharvestPro re-runs the US screen after the US close (4:00 p.m. ET), so a fresh list is typically ready in the Asian morning, before Tokyo, Taipei or Hong Kong open.
Is a US screener a buy list?
No. It narrows ~5,700 stocks to a short list of candidates for research. Your own chart analysis, risk management and entry timing always come after the screen. This content is educational and not investment advice.
Is it free?
The interactive screener has a free tier, and the daily US candidate lists and momentum breadth dashboard are free to view. No payment is required to start researching US leaders.
常見問題
我可以從日本、台灣或香港篩選美股嗎？
可以。AlpharvestPro 每個美國交易日對整體美國市場（NYSE/NASDAQ）進行篩選，並在亞洲早晨的時區公布主流強勢股。不需要開設券商帳戶就能研究美股候選標的；只有在你決定交易時，才需要美股市場的交易管道。
我應該篩選 S&P 500 還是整體美國市場？
從 S&P 500 開始——流動性高，可過濾掉不可靠的微型股。等到你想發掘規模較小的早期主流股、且能接受更多雜訊時，再擴展至約 5,700 支的整體市場。
篩選美股動能的最佳方式是什麼？
以相對強度對選股範疇排名（保留 RS ≥ 70），確認第二階段上升趨勢，並尋找樞軸附近緊湊的 VCP 底部——再確認整體美股市場寬度是否具有支撐性。這個組合篩選方法，正是區分真正主流股與僅當日上漲股票的關鍵。
美股篩選器針對亞洲時區何時更新？
AlpharvestPro 在美股收盤後（美東時間下午 4 點）重新執行篩選，因此最新清單通常在亞洲早晨、東京、台北或香港市場開盤前便已就緒。
美股篩選工具的結果是買進清單嗎？
不是。它將約 5,700 支股票縮小至少數研究候選標的。你自己的圖表分析、風險管控與進場時機，始終是在篩選之後才進行的。本內容僅供教育目的，不構成投資建議。
免費使用嗎？
互動式選股工具設有免費方案，美股每日候選標的清單與動能寬度儀表板均可免費瀏覽。開始研究美股主流股無需付費。
