PubMatic, Inc.

PubMatic spent most of the past two years in a broad decline — from above $20 in mid-2024 to a $6.15 low — and has since more than doubled, closing at $12.73, +107.0% off the 52-week low and −9.3% below the $14.04 high. The 90-day picture is a strong staircase uptrend (ADX 37.9) with relative strength firmly positive versus the Nasdaq Composite, but the week ended with a pullback: a bearish RSI divergence into the July 15 high, a fresh MACD dead cross on July 16, and a high-volume down day that closed below the 5- and 20-day averages. The useful lens here is a strong trend taking its first meaningful rest — where the pullback lands, and on what volume, matters more than the dip itself.

① Price & Moving Averages

Chart unavailable — PUBM_price-90d-2026-07-17.svg

The 90-day chart is a textbook staircase: higher highs and higher lows from roughly $8 in March to the $13.83 swing high on July 1, with the 5-, 20- and 60-day averages stacked in bullish order beneath price for most of the run. Friday changed the near-term tone — the close at $12.73 fell back through SMA5 ($13.48) and finished just under SMA20 ($12.91), which also sits at the Bollinger midline. Measured against the June 22 to July 1 up swing ($11.30 to $13.83), the close now sits between the 38.2% retracement at $12.86 and the 50% level at $12.57 — still inside the zone where routine pullbacks in healthy trends typically stabilize. Below that, the 61.8% level at $12.27, the 78.6% level at $11.84 and the rising SMA60 at $11.35 form a deeper support stack, with the 90-day aVWAP at $11.54 in between. Overhead, the 2024 breakdown left a large unfilled gap between $14.32 and $18.74 (from August 9, 2024) directly above the $14.04 yearly high — meaningful supply the trend has not yet had to digest.

② Volume

Chart unavailable — PUBM_volume-90d-2026-07-17.svg

Friday's decline printed 835,600 shares against a 558,245-share 20-day average — about 1.5× normal turnover on a down bar, which tilts the day toward genuine selling rather than a quiet drift. That said, 1.5× is elevated, not panic-grade; the 90-day window shows a handful of much larger yellow spike days (2×+) during the rally, several of which were accumulation days on advances. For a pullback to remain constructive, the pattern to look for is contracting volume as price digests, then expansion returning on up days. A second consecutive high-volume decline through the $12.57 area would be a clear escalation of the distribution case. With roughly $7 million in average daily dollar volume, liquidity is adequate for a small cap, though spreads can widen on fast days.

③ MACD

Chart unavailable — PUBM_macd-90d-2026-07-17.svg

MACD crossed below its signal line on July 16 — a fresh dead cross with the MACD line at 0.55 versus the signal at 0.63 and the histogram just negative at −0.08. Context matters: the cross occurred well above the zero line after an extended advance, which is the profile of momentum cooling within an uptrend rather than a trend reversal — the two prior dead crosses in this 90-day window (mid-May and mid-June) both resolved into consolidations that the trend later absorbed. Even so, a dead cross from a lofty level is exactly how deeper retracements begin, so it should not be waved away. The constructive resolution would be the histogram bottoming shallowly and re-expanding within a couple of weeks; a MACD line that keeps falling toward zero would confirm the pullback has more room to run.

④ RSI

Chart unavailable — PUBM_rsi-90d-2026-07-17.svg

RSI has dropped to 50.9 — the midline — after the chart run flagged a bearish divergence: on June 1 price closed at $12.22 with RSI at 78.44, and on July 15 price made a higher high at $13.80 while RSI printed a lower high of 69.85. Rising price on fading momentum is a classic late-stage warning, and this one has already been partially "paid" by Friday's drop. Two cautions cut in opposite directions here. First, a divergence is a possibility of reversal, not a verdict — in strong trends they frequently resolve through time and sideways digestion rather than a deep decline. Second, the midline test is informative: in established uptrends RSI tends to find footing in the 40–50 band, so a hold and turn from here would suggest the trend's character is intact, while a slice down into the 30s would mark a change in behavior versus the entire March-to-July advance.

⑤ Mansfield Relative Strength

Chart unavailable — PUBM_rs-90d-2026-07-17.svg

Mansfield RS versus the Nasdaq Composite stands at +25.7% — deeply in outperformance territory after crossing above zero in early June, ending more than a year below the line. The monthly trajectory is emphatic: RS was +7.2 a month ago, so the stock has added roughly 18.5 points of relative outperformance in four weeks — acceleration, not just persistence. The weekly read is softer: RS was +29.2 last week, so it has slipped about 3.6 points — outperformance that is still strongly positive but slowing at the margin, consistent with a stock resting after a sprint. For swing purposes this is one of the more supportive panels on the chart: pullbacks in positive, rising-slope RS names are statistically friendlier territory than dips in market laggards. A break of RS back below zero would remove that tailwind entirely.

⑥ ATR & ADX

Chart unavailable — PUBM_atr_adx-90d-2026-07-17.svg

ADX at 37.9 reads as a strong trend, and on this chart the trend it is measuring is the up move — but remember ADX measures strength, not direction, so if the pullback deepens, a high ADX will keep describing whatever move dominates. ATR is $0.56, or about 4.39% of price, and has been expanding through July: daily swings of half a dollar are normal here, so entries and stops sized for a quieter stock will get shaken out by noise. The mechanical references from the chart run are a 1×ATR stop at $12.17 and a 2×ATR stop at $11.61 — the latter sits below the 78.6% retracement ($11.84) but above the June 22 swing low ($11.30), a reasonable structural neighborhood for invalidation. With a 4.4% daily range, position size — not conviction — is the primary risk control.

⑦ OBV

Chart unavailable — PUBM_obv-90d-2026-07-17.svg

The two timeframes disagree here, and both are worth stating. On the 90-day window OBV is tagged improving — it sits a hair below its 20-day average (−0.17%) but the slope is rising, and the cumulative line climbed steadily all the way through the rally, confirming that the advance was bought, not just marked up. On the 2-year window the tag is early distribution: OBV is below its MA20 (−0.14%) with a flat slope, meaning the long-horizon accumulation impulse has paused right as price stalls under the yearly high. Neither divergence is large — both readings are within a fifth of a percent of their averages — so this is a panel on a knife's edge rather than a loud warning. If OBV rolls decisively below its average on both timeframes while price holds flat, that quiet supply would be the earliest tell that this pullback is more than a rest.

Key Levels nearest to price, from the chart run

What to Watch

• The $12.86–$12.57 zone. A hold on shrinking volume keeps this a routine 38.2%–50% pullback; a high-volume close below $12.57 opens the deeper-retracement path toward $12.27–$11.84.
• Volume symmetry. After Friday's 1.5×-average down day, the trend needs down-day volume to contract and up-day volume to expand. Two heavy red bars in a row would escalate the distribution case.
• RSI at the midline. A turn back up from the 40–50 band preserves the uptrend's character; a drop into the 30s would be behavior this advance has not shown since March.
• OBV on both timeframes. The 90-day line is still rising while the 2-year line reads early distribution — whichever resolves first (both above or both below their MA20s) likely tips the balance.
• MACD histogram depth. A shallow trough and quick re-expansion mirrors the May and June pauses; a MACD line sliding toward zero says the rest period will be longer.
