Our own calculation from the exchange’s daily candles, as of Oct 26, 2026. “All-time” applies since the start of this series, not to the whole market. Changes in percent; the TradingView chart shows prices. “Today” = change of the last trading day versus the previous day. Not investment advice.
No buy zone
There is currently no buy zone for this symbol under our Elliott rule. One only forms when the price pulls back after a strong rise.
An observation, not investment advice
Rule (4-hour candles) No active buy zone – the last one ended on Oct 19, 2026 · Buy zone no longer valid Zone historyThe zone history shows since when a buy zone has applied, when it was adjusted and when the price touched or left it. Recording began on Oct 12, 2026, only runs forward and fills nothing in – older zones are marked “known at start of recording” or “already existing when added”.Example: New buy zone on Oct 14, no adjustment since → “zone valid since Oct 14, 2026 · unchanged since”.More in the Academy: Lesson buy zone and Fibonacci

Timeframe 1 week · As of Oct 23, 2026 · display only, the rule works on 4-hour candles
Elliott count: Zigzag (A-B-C), Corrective pattern (upward), C complete (2 of 2 guidelines) · B = 64% of A; C = 107% of A
Comparison: The rule treats the last rise as the possible start of an upward impulse (without checking its history and structure). The Elliott count reads it as the end of an upward correction (C).
Note: Structure ambiguous: leg C can also be read as three- or five-part.
Elliott count calculated automatically by fixed Elliott rules, not investment advice – display only, our buy zones do not use it. Provisional: The count can change with new candles.
Automated analysis (rule-based): the rule calculates waves and Fibonacci levels from the completed weekly candles; the chart is recalculated every day. Not investment advice. On this timeframe the chart only shows the rule setup (swing detection 2 × ATR) – the rule itself works on 4-hour candles. Axis and values: distance from the top of the buy zone in %, no prices. Fibonacci measured logarithmically (weekly candles).

Elliott count: Flat (type known only after C), Corrective pattern (downward), C in progress (2 of 3 guidelines) · B = 108% of A; C = 146% of A
Note: Flat type (regular, expanded, running) can only be decided once C is complete.
Note: Structure ambiguous: leg B can also be read as three- or five-part.
Note: Retracement at least 88.7% of A: flat possible (B in progress, type only with C).

No buy zone of the rule on this timeframe – the chart shows only the Elliott count from the completed daily candles (recalculated every day). Not a recommendation, not investment advice. Without a buy zone there is no reference for percentages – so no value axis and no prices; measurements are ratios of wave lengths.

Weighting Main scenario (2 of 2 guidelines, strong) · no alternative Guidelines (strength of the count)Guidelines are typical features of a count, such as usual Fibonacci lengths or a change in the form of correction. Strong means: at least three quarters met, medium: at least half, otherwise weak. Even a strong count can flip.Example: 3 of 3 guidelines → strong; 2 of 4 → medium; 1 of 3 → weak.More in the Academy: Lesson wave degrees
Weighting by guidelines met – not a probability.
As long as the weekly close stays below the end of C, this applies: sharp countermove upward in three waves (Zigzag A-B-C), C complete – count points to falling prices.
Invalid if the weekly close is above the end of C (+34.2% from the top of the zone)
If that breaks, this count no longer applies. Currently no alternative that follows the rules.

Fiscal year 2025 (Jan 1, 2025 – Dec 31, 2025): Revenue 9.0B USD · Net income 3.5B USD · Net margin 39.0%
Each light follows a simple, disclosed rule. The comparison is with the sector median Sector medianThe middle value of all companies in a sector: half are above it, half below. Unlike the average, single outliers hardly distort it.Example: Margins 4%, 8%, 10%, 12%, 60% → median 10%, average 18.8%.More in the Academy: Lesson putting the P/E in context of all 97 symbols in the Technology sector on our list (current members of the S&P 500 and other lists).
+31.2% per year, last 5 years
Sector Technology: median +13.5% (88 symbols)
What does this mean? Revenue: over 5 years it grew by 31.2% per year on average – at least as fast as the median company in the sector (+13.5%).
Light rule: Green: grows at least as fast as the sector median (without a sector comparison: grows) · Yellow: grows more slowly · Red: shrinks.
+40.8% per year, last 5 years
Sector Technology: median +13.3% (62 symbols)
per share: +40.7% per year (5 years, split-adjusted)
What does this mean? Total net income: over 5 years it grew by 40.8% per year on average – at least as fast as the median company in the sector (+13.3%).
Light rule: Green: grows at least as fast as the sector median (without a sector comparison: grows) · Yellow: grows more slowly · Red: shrinks.
39.0% last fiscal year
Sector Technology: median 12.5% (97 symbols)
What does this mean? Of every 100 USD in revenue, 38.99 USD remained as profit – at least as much as the median company in the sector (12.5%). Five years ago the margin was 27.4%.
Light rule: Green: at least the sector median (without a sector comparison: profit) · Yellow: profit, but below the median · Red: loss.
– latest balance sheet
Sector Technology: median 0.46 (65 symbols)
What does this mean? No usable figure: reported financial debt or positive equity for the same balance sheet date is missing.
Light rule: Green: at most the sector median · Yellow: up to twice the median · Red: more than twice · Gray: without a sector comparison.
– Dividend / earnings per share
Sector Technology: median 30% (36 symbols)
What does this mean? The loaded SEC filings of the last two fiscal years contain no dividend per share. Either the company pays none, or it reports it under a different tag.
Light rule: Green: up to 60% of earnings · Yellow: up to 100% · Red: more than earnings or a dividend despite a loss · Gray for real estate (REITs). The sector median is for comparison only.
10 of 10 fiscal years with a profit
What does this mean? In 10 of the last 10 fiscal years the bottom line showed a profit. There were no losses in this period.
Light rule: Green: profit in every year · Yellow: one loss year · Red: several loss years (at least 3 years needed).

How we calculate: values as first reported to the SEC (later corrections are left out), a fixed order of reporting tags per figure, partial sums are never added up. Growth per year Growth per year (CAGR)The average annual growth rate over several years, as if the value had grown equally strongly every year. Individual good or bad years even out in it.Example: Revenue €100m → €161m in 5 years → (161 ÷ 100) to the power of 1/5 − 1 = 10% per year.More in the Academy: Lesson debt, dividends and growth over 5 years (otherwise 3 years). Per-share values adjusted for stock split Stock splitA company divides each share into several new ones; the value of the company stays the same. We convert per-share values from before the split to today’s scale.Example: Split 4 : 1, earnings per share before $11.89 → comparable today $2.97.More in the Academy: Lesson revenue, profit and margin 4:1 (between Nov 2, 2021 and Feb 15, 2022), 4:1 (between Nov 8, 2024 and Feb 19, 2025). Quarters are labeled by the calendar quarter in which they end.

ATR ATR (Average True Range)The average range per trading day over the last 14 days. It makes distances comparable, whether a stock costs 10 or 1,000.Example: ATR 2.50 at a price of 100: 0.4 ATR is 1.00, i.e. 1%.More in the Academy: Lesson ATR and moving averages as price values only when logged in.
