MGNI Stock Explodes 14.3% on Rosenblatt Price Target Upgrade to $39

The Catalyst

MGNI just went absolutely ballistic! Up 14.3% to $24.11 after Rosenblatt Securities dropped a monster price target upgrade - jacking their target from $18 all the way to $39. That’s not just bullish, that’s “we think this thing’s about to double” bullish.

When analysts more than double their price targets overnight, they’re seeing something the market hasn’t figured out yet. Rosenblatt’s basically saying MGNI’s at an inflection point where connected TV advertising is about to explode, and this adtech leader is positioned to capture massive market share.

This Isn’t Your Average Analyst Upgrade

Think about it - going from $18 to $39 means Rosenblatt sees 117% upside from their old target. These guys don’t throw around numbers like that unless they’ve got serious conviction about accelerating fundamentals. The connected TV advertising space is experiencing a gold rush, and MGNI’s the company selling the picks and shovels.

Here’s what’s got Rosenblatt fired up: Streaming services are finally cracking the code on premium video advertising, and every dollar moving from linear TV to streaming flows through platforms like Magnite. With cord-cutting accelerating and streaming ad inventory exploding, MGNI’s sitting at the epicenter of a massive secular shift.

Technical Setup

MGNI’s been quietly building momentum for weeks, grinding higher from that $18 base where it got stuck in May. The stock was coiling between $20-21 like a compressed spring, testing that resistance level multiple times before today’s analyst-driven explosion.

What’s lighting me up about this setup:

• Smashed through $21.50 resistance like it was made of paper
• RSI at 75 but momentum stocks don’t care about overbought levels
• Gapped clear above all moving averages on massive volume
• Next resistance doesn’t show up until $26-27 range
• 128% volume surge screams institutional accumulation

When you break out on analyst upgrades with this kind of volume, the party’s just getting started.

When Rosenblatt more than doubles a price target, they’re not just being optimistic - they’re seeing fundamental acceleration that the market hasn’t priced in yet. MGNI’s breakout on massive volume tells you institutional money agrees with this thesis.

The connected TV advertising boom isn’t a maybe - it’s happening right now. Every streaming service is adding ads, every advertiser is shifting budgets from linear TV, and every dollar flows through platforms like Magnite. This is a secular tailwind that could last for years.

At $24, MGNI’s still trading at a massive discount to Rosenblatt’s $39 target. Sometimes the best trades are hiding in plain sight in sectors experiencing explosive growth. The adtech revolution is real, and MGNI’s leading the charge.

The technical setup couldn’t be cleaner - analyst upgrade, volume surge, clean breakout above resistance. This has all the ingredients for a sustained run higher.

What I’m Watching Tomorrow

• Pre-market action and any follow-up analyst coverage
• Whether we hold $23.50 as new support
• Volume staying hot above 3M shares
• Any competitor downgrades as money rotates to MGNI
• Connected TV advertising headlines
• Gap above $25 and we’re testing $27 fast

When Wall Street’s top analysts start throwing around $39 targets on $24 stocks, you better pay attention. The connected TV revolution just got its stamp of approval.

The convergence of secular growth, analyst validation, and technical momentum makes MGNI one of the most compelling breakout stories in today’s market.
