Global bond yields are seeing some of the strongest upward pressure in over a decade, with 10 year yields in key markets sitting at multi year highs. That has put management teams and analysts under the spotlight, since funding costs and growth expectations now matter more to valuations. This article highlights three fast growing stocks with high insider ownership that align with that backdrop and that may be worth a closer look.

The stocks highlighted below are only a small sample, with the full screen surfacing 1,320 more companies where insider ownership and growth expectations create similarly compelling stories that are not covered here. To identify, analyze, and focus on the opportunities that best fit your own criteria, head straight into the Fast Growing Stocks With High Insider Ownership screener.

Nebius Group (NBIS)

Overview: Nebius Group is a technology company that builds full stack infrastructure for the global AI industry, including large scale GPU clusters, cloud platforms, and developer tools, alongside its TripleTen reskilling platform and Avride autonomous driving unit.

Operations: Nebius Group generates the bulk of its revenue from Nebius AI Cloud at about US$1.31 billion, with smaller contributions from TripleTen at US$52.9 million and Avride at US$2.8 million, partly offset by US$10.4 million of eliminations.

Market Cap: US$76.1 billion

Nebius Group sits at the center of the AI infrastructure buildout, with Nebius AI Cloud already driving around 98% of revenue and a reported backlog above US$40 billion backed by multi year contracts from customers like Microsoft and Meta. Analysts expect very fast earnings and revenue growth, supported by expanding data center capacity, a close Nvidia alliance, and substantial prepayments that help fund heavy capex. At the same time, the stock carries meaningful risks, including high valuation uncertainty, heavy reliance on external funding, intense competition in AI cloud, and signs of insider selling. For investors who want exposure to AI infrastructure growth but are conscious of execution and regulatory risks, Nebius Group is a story that warrants closer attention beyond the headlines.

Nebius Group’s huge AI cloud backlog and Nvidia ties are only part of the story. Before you assume the opportunity outweighs the pressure from heavy funding needs and insider selling, scan the 1 key reward and 4 important warning signs (2 are major!)

MasTec (MTZ)

Overview: MasTec is an infrastructure engineering and construction company that builds and maintains critical networks for communications, clean energy, power delivery, pipelines, transportation, and water systems across the United States and Canada. Its crews design, install, and service everything from fiber and 5G towers to renewable power projects, transmission lines, pipelines, and data center related electrical work for large utilities, telecoms, industrial clients, and government entities.

Operations: MasTec generates most of its revenue from Clean Energy and Infrastructure at about US$5.6b and Power Delivery at about US$4.5b, followed by Communications at about US$3.5b and Pipeline Infrastructure at about US$2.6b, with smaller eliminations between segments.

Market Cap: US$23.6b

MasTec attracts attention because it operates in several long term build outs, including grid upgrades and renewables, fiber, 5G, pipelines, and data centers. The company reports a record US$21.4b backlog, along with the recent Superior Group acquisition in mission critical electrical work. Reported earnings growth has been strong, and some analysts anticipate further increases supported by margin initiatives and higher forecast return on equity. At the same time, the stock is described by some sources as trading below certain fair value estimates and consensus targets. On the other hand, MasTec has taken on meaningful debt to fund growth, has client concentration in large projects, and has seen signs of insider selling, which could be relevant if policy, demand, or execution were to fall short of expectations. For investors who carefully weigh these trade offs, MasTec may warrant a closer look beyond the headline backlog.

MasTec’s record US$21.4b backlog and multi segment exposure can look like pure upside; yet the real story may sit in how its growth, debt load, and margins fit together in the analysis report for MasTec

Nu Holdings (NU)

Overview: Nu Holdings is a digital banking group that offers app based credit cards, current accounts, savings, loans, investing, crypto trading, insurance, and travel and mobile services to customers across Brazil, Mexico, Colombia and a few other markets. It aims to replace traditional branch based banks with a low cost, mobile first platform that bundles most everyday financial needs in one place.

Operations: Nu Holdings generates virtually all of its US$8.4b in revenue from banking services, with most revenue currently coming from Brazil at about US$13.7b, followed by Mexico and other countries at much smaller levels.

Market Cap: US$73.6b

Nu Holdings stands out because it combines a widely used consumer app across Latin America with profitability metrics that many banks aspire to, including high returns on equity and strong net margins. Earnings growth over the past few years has been rapid, revenue forecasts remain robust, and recent results highlight scale benefits as the customer base expands in Brazil, Mexico and Colombia. At the same time, a high level of bad loans around 8.6% and a relatively new management team introduce credit and execution risk. For investors who can balance that risk against the growth profile and current fundamentals, the full Nu Holdings case may merit a closer look beyond headline numbers alone.

Nu Holdings pairs high returns and a fast growing app with credit costs that deserve closer attention. See how the story looks when future expectations meet the detailed analyst forecasts for Nu Holdings and one underappreciated risk that could shift the picture
