Meta at $645: Recent Momentum Makes One Thing Very Clear

Meta just outran a falling market by more than 7 points in a single month, yet the stock still trails the S&P 500 by nearly 13 points year to date and carries a capex bill that cratered free cash flow…

At $644.38, Meta (NASDAQ:META | META Price Prediction) screens attractively here. The stock has climbed 7.55% higher over the past month even as the S&P 500 slipped, and that divergence is the tell.

Meta owns the world’s largest social advertising engine through Facebook, Instagram, WhatsApp, Messenger, and Threads, and now runs a rapidly scaling AI stack anchored by Meta Superintelligence Labs and the MuseSpark model family. The company reaches 3.60 billion daily active people across its Family of Apps.

The stock got there by surviving a bruising summer. Shares sold off after a Q2 miss and a raised capex bar, but the setup has quietly repaired itself as ad growth accelerated and AI product traction became visible.

Why the AI Ad Engine Justifies a Higher Multiple

Advertising revenue grew 27% year over year to $59.36 billion in Q2, with ad impressions up 14% and price per ad up 12%. Meta’s GEM ad-ranking system drove an 8.3% lift in Facebook ad clicks and a 15.7% conversion uplift, while Advantage Plus crossed a $75 billion annual revenue run rate.

Valuation looks reasonable. Shares trade at 23x trailing earnings and 18x forward, with a PEG of 0.812, 30.2% ROE, and 41.4% operating margins. Business agents already serve more than 1 million businesses weekly, opening a subscription and API monetization layer beyond ads.

Where the Capex Bill Could Break the Thesis

Q2 free cash flow collapsed to $784 million from $8.55 billion, a 91.31% drop, as capex hit $31.1 billion. Operating margin compressed to 31% from 43%, and EPS of $6.18 missed by 14.42%, ending a six-quarter beat streak.

Full-year 2026 capex guidance sits at $130 billion to $145 billion, expenses at $165 billion to $169 billion, and legal charges added $2.40 billion in a single quarter with youth-safety trials still ahead. A spend of that size flows straight to the power, cooling, and networking suppliers behind the data centers (we profiled seven of them in a free AI infrastructure report). Reality Labs continues to bleed, posting a $4.03 billion Q1 operating loss. If AI monetization slips, the returns math gets ugly fast.

Why Patience Has an Argument Too

The 2026 EPS consensus has drifted from $33.05 thirty days ago to $31.37, with 45 downward revisions against 4 upward in the last month. That is a real signal that the Street is still absorbing the spending ramp.

A patient investor could wait for Q3 results, the Connect event on September 23, and resolution of youth-safety litigation before committing. The cost of waiting, though, is watching the stock rerate without you.

What the Numbers Say About the Setup

Meta trades at $644.38 against a consensus analyst target of $754.15, implying roughly 17% upside. The rating mix is decisively bullish: 8 Strong Buy, 47 Buy, 7 Hold, 0 Sell, 0 Strong Sell. Targets are one data point, not a promise.

Performance tells the momentum story. Meta is up 5.52% over the past week and 7.55% over the past month, while the S&P 500 is down 1.97% and 1.64% over those windows. Year to date Meta is off 2.21% versus the SPDR S&P 500 ETF Trust (NYSEARCA:SPY)’s gain of 11.15%, meaning most of the AI-capex reset is already in the price.

Buy Verdict on Meta at Current Levels

At $644.38, Meta screens as an attractive setup. Here is why.

The path to appreciation runs through three near-term catalysts: Q3 revenue guided to $61 billion to $64 billion, the Connect keynote unveiling the EssilorLuxottica AI glasses lineup, and continued conversion gains from GEM and Advantage Plus. Any one of those printing cleanly recompresses the risk premium the stock has carried since July.

The entry point matters. Buying at a forward P/E of 18 for a business growing ad revenue 27% with 30%+ ROE is the kind of setup that historically compounds. The bear case is fully visible in the price action: shares still trail the S&P by nearly 13 points year to date, and estimates have already been cut. The market has done the derisking.

The thesis breaks if 2027 capex guidance shocks higher without matching revenue acceleration, if a youth-safety verdict lands materially above the $2.4 billion already booked, or if ad pricing rolls over. Watch quarterly free cash flow and the ratio of capex growth to ad revenue growth.

When a mega-cap outruns a falling market on improving fundamentals and a compressed multiple, that is a meaningful signal.
