AMBA

AMBA (Ambarella, Inc. Ordinary Shares) currently scores 67/100 with the signal label CONSTRUCTIVE. The score is a weighted blend of six quantitative factors and updates sub-60 seconds during US market hours.

The Tapeline Score is a transparent weighted blend of six named factors: Trend, Relative Strength, Fundamentals, Smart Money, Macro, and Momentum — weighted most toward Trend and Relative Strength, and least toward Momentum. Each sub-score is normalised to 0-100 and the methodology is published on /how-it-works.

Tapeline doesn't issue buy or sell calls — we publish descriptive analytics, not investment advice. The signal label CONSTRUCTIVE describes the current state of the data; whether AMBA fits your portfolio depends on your risk tolerance, time horizon, and tax situation. See the risk disclosure for details.

AMBA's score re-ticks every minute during US market hours and persists between sessions. Price and momentum data refresh sub-60s; fundamentals refresh on company filing cadence; insider Form 4 within hours of SEC filing.

Every Tapeline top-10 daily pick is auto-published with the next-day return vs SPY at /scorecard. The scorecard is immutable — every call is preserved with its original context for accountability.

CONSTRUCTIVE is a descriptive band on the Tapeline composite. HIGH CONVICTION (85-100) means all six factors aligned; STRONG SETUP (70-84) typically four-or-five-of-six; CONSTRUCTIVE (55-69) net-positive with tradeoffs; NEUTRAL (40-54) factors cancel; CAUTION (25-39) more negative than positive; WEAK (0-24) broadly negative. AMBA sitting at CONSTRUCTIVE means the data right now reads as constructive for the six-factor profile.

The Tapeline composite is calibrated for multi-day setups — the heaviest-weighted factors (Trend, Relative Strength, and Fundamentals) reward stability over a horizon of days-to-weeks. For pure day trading, the 1-day move + sub-momentum factor is more relevant. Use /best-stocks-for/day-traders for the day-trader-sorted view and /best-stocks-for/swing-traders for the multi-day setup view.

Sector ranks are computed across the actively-scored universe (~2,500 US tickers by daily $-volume) so the cohort is consistent across all the information technology sector names Tapeline covers.

AMBA's Smart Money sub-score blends SEC Form 4 insider transactions, Congressional disclosures where applicable, and ETF/institutional flow signals. Detailed Form 4 history per ticker is a Premium feature; the aggregate Smart Money sub-score is shown on this page for free.

Scores re-tick every minute during US market hours. Trend and Relative Strength move with price; Momentum reflects recent rate-of-change; Macro responds to VIX, breadth, and 10Y yield shifts; Smart Money updates on filing cadence; Fundamentals on quarterly earnings cycle. Across a single trading session AMBA's composite can drift 5-15 points in either direction even without major news — that's normal factor breathing, not data error.

Finviz exposes raw filter fields — you build a thesis from the data. Tapeline synthesises six factors into one composite + a plain-English Why, so the work is done before you look at the row. Both are useful for different jobs: Finviz Elite for power-user raw-filter scans, Tapeline for daily synthesised rankings + per-pick public scorecard. Many traders use both — see /best-finviz-alternatives for the head-to-head comparison.
