Key Highlights

  • Four of the five names gained between 24.33% and 38.19% over one week, with Perion Network (NASDAQ:PERI) up 31.62% as it moves toward an all-cash USD 11.70 per share offer from Affle announced November 1, 2026.
  • Magnite (NASDAQ:MGNI) climbed 24.33% over one week to USD 27.03, helped by third quarter Revenue of USD 204.2 million, up 14%, and a 2026 contribution ex-TAC growth outlook lifted to about 17%.
  • Stagwell Inc. (NASDAQ:STGW) closed at USD 10.73 despite a 2.45% decline in the latest session, while EverQuote (NASDAQ:EVER) finished at USD 30.57 after a 38.19% weekly gain.

MediaAlpha (NYSE:MAX): Monthly Gain Follows a Third Quarter Beat and Share Repurchases

MediaAlpha (NYSE:MAX) finished at USD 15.08, up 55.41% over a month and 7.37% over a week, while the latest session added only 0.17%. The move followed third quarter results released on October 28, 2026, when revenue of USD 376 million grew 23%, contribution climbed 26% to USD 57 million and adjusted EBITDA of USD 39 million rose 36%. Fourth quarter revenue guidance of USD 355 million to USD 375 million implies about 25% growth at the midpoint, by simple arithmetic. Since September 2025 the company has bought back roughly USD 115 million of stock and trimmed its share count by about 11.2 million, or 16%, which lifts per share Earnings mechanically. Cash stood at USD 18.7 million, and USD 10 million was drawn on the revolving Credit line afterward to fund repurchases. Market Value is near USD 887 million on roughly 58.8 million shares (calculated). Borrowing, carrier ad budgets and a Reversal after a 55.41% run are the main risks for MediaAlpha (NYSE:MAX), and the snapshot contained no P/E.

Perion Network (NASDAQ:PERI): Weekly Surge Reflects an All-Cash Takeover Offer

Perion Network (NASDAQ:PERI) climbed 31.62% over one week to USD 11.43, slipping 0.22% in the latest session. This is a Merger repricing, not an earnings surprise. Affle agreed on November 1, 2026 to acquire the company for USD 11.70 per share in cash, an Equity value of about USD 420 million that represents a 34.5% premium to the October 30 close. Simple arithmetic puts that close near USD 8.70, so most of the premium was already reflected in the share price. The remaining USD 0.27 gap, or 2.4%, reflects time to close, a Shareholder vote, Hart-Scott-Rodino clearance and a 40-day go-shop ending December 11, 2026. Market value sits near USD 410 million (calculated), which makes it a small cap. A failed deal could send the shares back toward USD 8.70, a drop of about 24% by simple arithmetic, so the stock now trades largely as a merger arbitrage position, and thin trading can widen spreads for Perion Network (NASDAQ:PERI).

Magnite (NASDAQ:MGNI): Third Quarter Beat and a Raised Contribution Outlook

Magnite (NASDAQ:MGNI) reached USD 27.03 after a 24.33% weekly gain, which included an 18.60% jump in the latest session following third quarter results released November 4, 2026. Revenue reached USD 204.2 million, up 14%, contribution ex-TAC climbed 20% to USD 200.6 million, and connected TV contributed USD 105.4 million, up 39%. Net Income rose 70% to USD 34.0 million, while adjusted EBITDA grew 46% to USD 83.4 million, a 42% margin. The catalyst is a beat paired with a raise, since 2026 contribution ex-TAC growth is now guided at about 17%, up from 13% to 14%. Operating Leverage explains the gap, because EBITDA grew 46% on 20% growth in contribution ex-TAC. Much of the re-rating predates the report, given a 96.72% six month gain. Cash fell to USD 392.9 million from USD 553.4 million after USD 205.1 million of convertible repayments. No market value or P/E was retrieved, and reported 2027 growth of 10% is a specific risk for Magnite (NASDAQ:MGNI).

Stagwell Inc. (NASDAQ:STGW): Third Quarter Results and Higher Adjusted EBITDA Guidance

Stagwell Inc. (NASDAQ:STGW) closed at USD 10.73, up 25.50% over one week and 25.20% over one month, even though the latest session brought a 2.45% decline. The catalyst was third quarter results reported October 29, 2026, with revenue of USD 816.0 million, up 10%, net revenue of USD 664.0 million, up 8%, and adjusted EBITDA of USD 144.8 million, up 25%, equal to a 22% margin. Management raised adjusted EBITDA guidance to USD 490 million to USD 540 million and adjusted EPS guidance to USD 1.07 to USD 1.21. Adjusted EPS of USD 0.34 sits well above GAAP EPS of USD 0.07, so both measures should be read together. Long Term Debt rose to USD 1,414.6 million from USD 1,326.0 million at year end 2025. After a 66.10% six month rise, Stagwell Inc. (NASDAQ:STGW) could reverse if Advertising budgets tighten, and its market cap and P/E were not verified.

EverQuote (NASDAQ:EVER): Record Revenue and a USD 50 Million Buyback

EverQuote (NASDAQ:EVER) closed at USD 30.57 after a 38.19% weekly gain and a 56.92% monthly gain, and was essentially flat on November 5, 2026. The catalyst was third quarter results filed November 2, 2026, which showed record revenue of USD 218.1 million, up 25%, and a beat of 7.6% against the USD 202.6 million consensus. Adjusted EBITDA rose 41% to USD 35.5 million. The fourth quarter revenue midpoint of USD 218 million topped a USD 212.5 million consensus, and the board approved a USD 50 million repurchase program, which can tighten the float in a small cap. Home and renters revenue rose 70% to USD 27.7 million. One published snapshot placed market value at USD 828.5 million at a USD 25.55 share price, so the current price implies a higher value, still within the small cap range. Auto insurance premium cycles drive lead volumes, and EverQuote (NASDAQ:EVER) may reverse the gain.

Where Things Stand

MediaAlpha led the one month rally at 55.41%, while EverQuote led the one week gains at 38.19%. Most of the reported catalysts are third quarter results with raised or reiterated guidance, plus Buybacks at MediaAlpha and EverQuote, and Perion Network moved on a cash takeover offer rather than on earnings. The lists cover the best-performing small caps (300 million to 2 billion USD) and mid caps (2 billion to 10 billion USD) in a published market data snapshot dated November 5, 2026. Gains of this size can unwind quickly, since a few trades can move a small cap price and spreads may be wide.
