How ALPHA AND OMEGA SEMICONDUCTOR LTD looks technically
ALPHA AND OMEGA SEMICONDUCTOR LTD (AOSL) is trading 5.1% below its 200-day average, the long-term trend line — a long-term downtrend. Its 50-day average crossed below its 200-day average about 14 trading days ago — a "death cross", a bearish long-term signal. There is no clear trend right now — the price is choppy (ADX, a 0–100 trend-strength gauge, is 17, below the 25 that marks a real trend). Momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 52, neither overbought (above 70) nor oversold (below 30). It made a new 20-day high about 5 trading days ago. It is 47.7% below its highest point of the past year.
Trend
8
| Distance from the 200-day | it is trading 5.1% below its 200-day average, the long-term trend line — a long-term downtrend | -5.1% |
|---|---|---|
| 50-day moving average | its average price over the last 50 trading days — a short-term trend line — is $28.20 | $28.20 |
| 200-day moving average | its average price over the last 200 trading days — the long-term trend line — is $29.94 | $29.94 |
| Swing structure | each recent peak has been higher than the one before it and each dip has been shallower — the pattern chart-watchers call an uptrend, which describes where price has already been and not where it goes next | higher highs and higher lows |
| Last swing turn | its last significant turn was a swing high 16 calendar days ago — the swings before that are what the structure reading is measured on | 16 sessions |
| Wave structure | its recent swings can be read as a five-part upward sequence — what Elliott-wave chartists call an impulse — now in the fourth leg, a pullback against that upward direction; the labelling fails if price closes below 26.25. It is the only labelling that fits, though not with textbook proportions, and it describes the swings already printed, not what comes next. | possible upward five-wave sequence, in wave 4 (atypical proportions) |
| Since the 50/200 cross | its 50-day average crossed below its 200-day average about 14 trading days ago — a "death cross", a bearish long-term signal | 14 sessions |
| Trend strength (14-day ADX) | there is no clear trend right now — the price is choppy (ADX, a 0–100 trend-strength gauge, is 17, below the 25 that marks a real trend) | 17.1 |
Momentum

| 14-day RSI | momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 52, neither overbought (above 70) nor oversold (below 30) | 52.4 |
|---|---|---|
| Position in its 14-day range | it is trading in the upper half of its 14-day range ($25.32 to $30.89) — its "stochastic" reading is 55 out of 100, where 0 would mean closing exactly at the 14-session low and 100 exactly at the high. This measures WHERE the price sits inside its recent range, which is a different question from the RSI beside it: RSI is a momentum gauge, measuring how FAST the price has been moving, so a stock can drift quietly to the bottom of its range with an ordinary RSI, or fall sharply and still sit in the middle. It has been slipping within that range over the last few sessions. | 55.5 |
| Since the MACD crossed zero | MACD, a trend-momentum gauge, is in positive territory (momentum leaning bullish) | 23 sessions |
Range

| 52-week high | its highest closing price over the past year (about 252 trading days) was $54.34 | $54.34 |

| From the 52-week high | it is 47.7% below its 52-week high (its highest price of the past year) | -47.7% |
| Above the 52-week low | it is 67.0% above its 52-week low (its lowest price of the past year) | +67.0% |

| Since a 55-day breakout | it made a new 55-day low about 27 trading days ago | 27 sessions |
| All-time high | its highest closing price on record is $69.99 (set on 2022-03-30) | $69.99 |
| Given back of the 52-week move | over the past year its closes ranged ($17.47 to $53.32), and it has given back well over two thirds of its rise from last year’s low — 69% of it. Chart-watchers call 61.8%-65% given back the "golden pocket" — for this company that is $30.02 to $31.16. It is watched widely enough that orders cluster there, which is the honest reason it matters; it is not a forecast. | 69.5% |
| From the all-time high | it is 59.4% below its all-time high | -59.4% |
| Nearest price level | it is sitting right on a support level at $28.36 — a price it turned at twice since 2025-03-19, most recently on 2026-09-22. Since 2024-10-08 it has 12 such levels below the current price and 5 above. Levels like these describe where the price has reversed or paused before; they are not a forecast of where it will go. | -0.2% |
| All-time low | its lowest closing price on record is $5.82 (set on 2020-03-23) | $5.82 |
| Above the all-time low | it is 388.1% above its all-time low | +388.1% |
Volatility
5
| Band width vs its own 6 months | day-to-day price swings are narrower than usual versus its own recent 6-month history (tighter than about 84% of it) | 16th percentile |
|---|---|---|
| Typical daily range | in a typical session it travels about $1.42 between its high and its low — about 5.0% of its price. That is its "average true range" over the last 14 sessions, which also counts the distance from the previous close, so a day that opens well away from yesterday counts as the large move it was | $1.42 |
| Bollinger bands (20-day, ±2σ) | most of its recent trading has stayed between about $23.78 and $30.79 — the "Bollinger bands", a range drawn two standard deviations either side of its 20-day average price, which widens when the stock gets more volatile and narrows when it settles | $23.78 – $27.29 – $30.79 |
| Typical daily range (% of price) | its price moves about 5.0% in a typical session — about typical for the companies we cover. This is the average gap between a session's high and low over the last 14 sessions, counting overnight moves, expressed against the current price so it can be compared with companies trading at any price | 5.0% |
| Stretch from the 200-day average | it is trading 1.1 daily ranges below its 200-day average price (5.1% below it in plain percentage terms) — a way of asking how far it has stretched from its own average in units of how far it normally moves in a day, so a calm company and a jumpy one can be compared on the same scale | 1.1 daily ranges below its 200-day average |

Price gaps
3
| Gap at the open | it opened on 2026-10-08 2.2% below the previous session's close — an overnight gap, the part of the move that happened while the market was shut, and traded back through that level before the close | -2.2% |
|---|---|---|
| Open gap | it gapped 3.4% below the previous close 1 session ago and has not traded back through the level it left behind at 29.94 — an "unfilled gap", which describes a price range no trade has since crossed and is not a forecast that it will be crossed | -3.4% |
| Gap filled | a 2.2% gap down opened on 2026-10-08 has been "filled" today — price traded back through the level the gap left behind, and it closed again during the very session that opened it | today |
Price streaks
1
| Closing streak | it has closed lower 2 sessions in a row, a -5.11% move over the run — an unbroken run of down days, which describes what has already happened and says nothing about the next session | 2 sessions down |

Signal agreement
2
| Bullish technical signals | 2 of the 9 technical signals we can compute for it are currently in a bullish state: MACD momentum is positive, outperforming the market over 6 months — these describe past price behaviour, not a forecast | 2 of 9 |
|---|---|---|
| Bearish technical signals | 2 of the 9 technical signals we can compute for it are currently in a bearish state: a "death cross" — its 50-day average is below its 200-day, trading below its 200-day average — these describe past price behaviour, not a forecast | 2 of 9 |
Trend (Ichimoku cloud)
1
| Vs the Ichimoku cloud | trading inside the Ichimoku cloud — a band drawn from where its own highs and lows sat up to 2026-09-01 and projected forward over today's price, the zone traders read as unresolved — neither side has established a trend, and the band is where that gets settled. The band itself is thick, spanning 33.5% of the share price, which is taken to mean a barrier that has held for a while and takes effort to cross. | 0.0% |
|---|
Volume-weighted price
2
| Vs this year’s average price paid | the price is 18% below the average price paid so far this year, so the typical buyer over that stretch is under water. That average is $34.68 — a volume-weighted average of daily closes over 190 sessions, not a true tick-by-tick VWAP. | -18.1% |
|---|---|---|
| Vs the average paid since it last reported | the price is 4% above the average price paid since it last reported on 2026-08-12 (its 8-K), so the typical buyer over that stretch is showing a gain. That average is $27.29 — a volume-weighted average of daily closes over 41 sessions, not a true tick-by-tick VWAP. | +4.1% |

A level is a price this company reversed or paused at more than once — they describe past behaviour, not a forecast of where the price will go.
Wave structure
Its recent swings can be read as a five-part upward sequence — what Elliott-wave chartists call an impulse — now in leg 4 of five, a pullback against that direction.
This labelling fails — stops being a possible reading at all — if it closes below $26.25.
It is the only labelling that fits these swings, though its proportions are not the textbook ones.
On past moves of this shape the leg has usually ended somewhere between $26.25 and $27.27 — that is where it has tended to end if the count holds, not a forecast of where the price goes.
This reading has stood for 8 trading days, since 2026-09-29.
Read from daily closes as of 2026-10-08.

Only open-market purchases (SEC code P) and sales (code S) are counted here. Option exercises, vesting/awards, gifts, and shares withheld for taxes are excluded — they are compensation or mechanical, not open-market conviction.

Reported to FINRA as of the 2026-09-15 settlement date. Short interest is reported to FINRA and published on a delayed, bi-monthly schedule (as of a settlement date, disseminated roughly eight business days later) — it is NOT real-time, does not cover every venue or all US trading, and is not a short-squeeze prediction or investment advice. Days-to-cover is the value FINRA reports; percent of float is not shown because the source file carries no share-count denominator — where a percent appears it is of shares OUTSTANDING, the larger base, and is therefore a floor on percent of float.
