Major indexes were volatile this week due to earnings from artificial intelligence companies, key economic releases, and the scandal involving Nvidia former CEO Jensen Huang. While short-term fluctuations could weigh on investor sentiment, it is prudent to maintain a long-term investment horizon.
Investors looking for attractive long-term picks can track the ratings of top Wall Street analysts and gain key insights from their in-depth research on the macro and micro factors impacting stocks.
Here are three stocks favored by some of Wall Street's top pros, according to TipRanks, a platform that ranks analysts based on their past performance.
Cybersecurity company Palo Alto Networks will announce its fiscal first-quarter earnings on Nov. 18. Migration to the cloud and the rapid adoption of AI have increased demand for cybersecurity solutions provided by Palo Alto and its peers. TipRanks' KPIs tool for PANW shows the rise in the company's subscription revenue over the years, driven by the adoption of its AI and security offerings and contributions from recent acquisitions.
Ahead of the upcoming earnings, Oppenheimer analyst Ittai Kidron reiterated a buy rating on Palo Alto stock with a price target of $450. The five-star analyst said that his checks indicate upside potential from CyberArk and Chronosphere acquisitions and strength in the company's core businesses.
Specifically, Kidron expects Palo Alto's Q1 FY27 next-generation security annualized recurring revenue to be about two percentage points above the midpoint of the guidance range and consensus, or $9.55 billion. He also sees nearly 1 to 1.5 percentage points of revenue upside compared to the guidance and consensus of $3.305 billion. Kidron expects management to remain conservative with its FY27 guidance and raise it by no more than the size of the quarterly beat.
Additionally, Kidron highlighted that partner checks indicated above-plan performance in the quarter, driven by firewall-attached subscriptions and strength in Prisma SASE and XSIAM offerings. The analyst also expects results to gain from CyberArk cross-selling and better-than-expected performance of Chronosphere as OpenAI completes its migration.
"While Prisma AIRS crossed $100M in ARR last quarter, the fastest product ramp in company history, partners still view CY27 as the first real revenue year," said Kidron.
Kidron ranks No. 638 among more than 12,500 analysts tracked by TipRanks. His ratings have been successful 55% of the time, delivering an average return of 10.5%. See Palo Alto Technical Analysis on TipRanks.
Next on this week's list is database software company MongoDB. Recently, BTIG analyst Gray Powell initiated coverage of MDB stock with a buy rating and a price target of $417. Powell estimates that currently the size of the company's core addressable market is nearly $15 billion, with several tailwinds to drive more than 20% revenue growth over the next few years.
Beyond its core document and vector businesses, Powell highlighted that MongoDB has exposure to about $72 billion of adjacent markets, projected to grow to about $121 billion over four years. With even modest share gains in adjacent markets, the five-star analyst believes that MongoDB can grow revenue at about a 24% annual rate over the next three years, above management's growth target of more than 20%.
Contrary to the bearish narrative, Powell views AI as an emerging tailwind for MongoDB, with application modernization creating new workloads while making migrations faster and cheaper. He added that interviews with eight contacts were generally constructive and indicated faster legacy migrations, growing non-relational adoption, and early traction in Voyage AI and Vector Search offerings.
Additionally, Powell sees upside to Atlas growth, driven by new products. "We see a meaningful product cycle led by MongoDB 9.0 and AMP, with Agent Engine and Atlas Infinite adding upside over time," said the analyst.
Powell ranks No. 480 among more than 12,500 analysts tracked by TipRanks. His ratings have been profitable 57% of the time, delivering an average return of 13%. See MongoDB Technical Analysis on TipRanks.
Membership-only warehouse chain Costco Wholesale recently announced a special cash dividend of $30 per share, payable on Dec. 4. The company also announced that its board has reauthorized a stock repurchase program of up to $4 billion, which will expire in November 2030 and replaces the current $4 billion program that is set to end in January 2027.
Following the announcement, Oppenheimer analyst Rupesh Parikh reiterated a buy rating on COST stock with a price target of $1,160. The five-star analyst said that the special dividend news is one of the key catalysts that he has been waiting for since Costco was added to Oppenheimer's top pick list in November 2025.
Parikh highlighted that the special dividend the company announced is significantly above his estimate of about $20 per share. The analyst expects the special dividend to reduce interest income substantially.
"COST remains a top pick for us, and we still see the potential for a stock split down the road, which could represent another positive catalyst for shares, in our view," said Parikh.
Overall, Parikh remains bullish on Costco's long-term prospects, backed by its value proposition, leading competitive position, and a solid track record of shareholder returns. The analyst also noted the company's strong management team and the ability to sustain top- and bottom-line growth even in a competitive retail backdrop.
Parikh ranks No. 324 among more than 12,500 analysts tracked by TipRanks. His ratings have been profitable 63% of the time, delivering an average return of 12.7%. See Costco Statistics on TipRanks.
