How PDF SOLUTIONS INC looks technically

PDF SOLUTIONS INC (PDFS) is trading 0.5% above its 200-day average, the long-term trend line — a longer-term uptrend. Its 50-day average crossed above its 200-day average about 253 trading days ago — a "golden cross", a bullish long-term signal. A trend is forming but not yet strong — ADX, a 0–100 trend-strength gauge, is 25 (a reading of 25+ marks a strong trend). Momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 44, neither overbought (above 70) nor oversold (below 30). MACD, a trend-momentum gauge, turned bearish about 7 trading days ago (its momentum flipped negative). It made a new 20-day low about 4 trading days ago. It is 38.6% below its highest point of the past year.

Position in its 14-day rangeit is trading in the lower half of its 14-day range ($38.80 to $56.98) — its "stochastic" reading is 29 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 climbing within that range over the last few sessions.28.7

Vs the Ichimoku cloudtrading 3.9% below the Ichimoku cloud — a band drawn from where its own highs and lows sat up to 2026-09-15 and projected forward over today's price, the side traders read as an established downtrend, with the band above acting as the level that would have to be cleared. The band itself is thick, spanning 17.3% of the share price, which is taken to mean a barrier that has held for a while and takes effort to cross.-3.9%

Wave structure

Its recent swings can be read as a three-part upward correction — the A-B-C shape chartists use for a pullback — now complete.

This labelling fails — stops being a possible reading at all — if it closes above $56.98.

It is the only labelling that fits these swings, though its proportions are not the textbook ones.

This reading has stood for 7 trading days, since 2026-10-13.

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. Sales may be planned and non-discretionary (e.g. a Rule 10b5-1 plan) and are not necessarily bearish; open-market buying is not a recommendation to buy. Informational only — not financial advice.

Change counts cover only managers that filed 13F reports in BOTH quarters, derived between two quarter-end snapshots — not same-day trades; a single manager is never said to have "bought" or "sold".

Institutional holdings are quarter-end long positions reported on SEC Form 13F-HR, filed up to 45 days after the quarter ends — they are delayed, are not real-time trades, exclude short positions and most non-US securities, and are not investment advice. Any increase/decrease is a reported change between two quarterly snapshots, not a same-day purchase or sale. These are quarter-end snapshots from the 13F filings on SEC EDGAR, filed within 45 days — not real-time, and any change is a difference between two quarterly reports, not a same-day trade.

PDFS had 8.39% of its shares outstanding sold short as of the 2026-09-30 FINRA settlement date (percent of FLOAT would be higher — float is not disclosed in the source). FINRA reported 5.81 days to cover at the same settlement.

Reported to FINRA as of the 2026-09-30 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.
