September is typically a weak month for equities, and higher interest rates have pushed some capital toward fixed-income assets such as certificates of deposit and short-term Treasury bills. That may make some investors reluctant to add to stock positions in the near term. Others willing to tolerate volatility are still looking at companies with significant long-term growth potential. Opendoor, NIO, Bloom Energy and Strategy have each been identified as stocks that could potentially deliver roughly fourfold gains over the coming years, with the original investment horizon extending to 10 years.
The four companies rely on very different growth drivers. Opendoor is exposed to interest rates and housing turnover; NIO must manage intense EV competition and the cost of expansion; Bloom Energy is positioned around rising electricity demand from artificial-intelligence infrastructure; and Strategy's valuation is closely linked to its bitcoin holdings and financing model.
Opendoor: Mortgage Rates Set the Pace
Opendoor is one of the largest instant-home-buying platforms in the United States. Its artificial-intelligence algorithms generate cash offers to sellers, after which the company buys, renovates and relists homes through its own marketplace. The model is better suited to periods of lower borrowing costs and active housing markets. When rates rise and transactions slow, Opendoor faces simultaneous pressure on inventory, financing and sales cycles.
The stock currently trades at about 0.3 times projected next-year sales, 93% below its historical peak on that measure. The valuation reflects concerns about elevated rates and a weak housing market. The Federal Reserve's recent rate hikes also suggest that near-term pressure may persist. If rates decline and housing activity recovers, both Opendoor's revenue base and valuation could regain support. Even a fourfold increase in the share price would not necessarily leave the stock looking expensive on its current sales multiple.
The price cited in the article was $2.57, up 1.58% on the day, or $0.04.
NIO: Deliveries and Profitability Must Improve Together
NIO is a significant EV maker in China and Europe, offering several battery-electric sedans and SUVs. Its vehicles use a removable-battery system that allows owners to swap batteries at dedicated stations, potentially reducing refueling time compared with conventional charging.
NIO delivered 326,028 vehicles in 2025. The stock trades at about 0.4 times projected next-year sales and is 94% below its historical high. Its shares have been affected by the substantial investment required to build a battery-swap network, as well as the cost of developing in-house automotive chips. Competition across the EV market has also limited pricing power and squeezed margins.
A notable development is that NIO finally reported adjusted profitability in the first half of 2026. If that improvement proves durable, the market could value the company more like Tesla, which trades at roughly 12 times projected next-year sales. The comparison still requires care, however, given the differences between the two companies in brand strength, scale, market position and earnings quality.
The article cited an NIO share price of $3.58, down 1.38% on the day, or $0.05.
Bloom Energy: A $20 Billion Revenue Base and $200 Billion Backlog
Bloom Energy develops solid-oxide fuel cells that generate electricity from natural gas, biogas, hydrogen and propane without combustion. Its systems can potentially be deployed in less than two months, while connecting to a conventional power grid often takes years. That timing has made distributed power an option of interest to data-center operators.
As electricity demand from AI data centers has accelerated, Bloom Energy's backlog reached $20 billion at the end of 2025, roughly 10 times the company's $2 billion in 2025 revenue. The stock has risen about 2,700% over the past two years, but it still trades at approximately 12 times this year's sales. Whether the valuation can continue to be supported by operations will depend on the conversion of the backlog into revenue, along with project delivery, costs and cash flow.
The price cited for Bloom Energy was $288.70, up 8.27% on the day, or $22.05.
Strategy: Bitcoin Holdings Exceed Its Market Capitalization
Strategy is one of the world's largest publicly traded corporate bitcoin holders, with 846,000 bitcoin. Based on the figures in the article, those assets were worth approximately $70.6 billion, above the company's market capitalization of about $66.3 billion. Even so, Strategy's shares were still trading at a discount to the net asset value of its bitcoin holdings.
The main market concern is how the company finances its purchases. Strategy raises equity and debt to fund additional bitcoin acquisitions and has sometimes sold part of its bitcoin holdings to pay preferred-stock dividends. The structure means shareholder returns depend not only on the price of bitcoin, but also on financing costs, balance-sheet changes, potential dilution and cash-payment obligations.
Bitcoin had risen nearly 40% over the previous three months to approximately $83,000. Michael Saylor, Strategy's executive chairman, has said bitcoin could reach $21 million by 2046. If that forecast were ultimately realized, the company's shares could deliver substantial multiple returns over the next decade. Until then, Strategy remains exposed to bitcoin's price volatility and to valuation changes arising from its financing arrangements.
The article cited a Strategy share price of $158.61, down 1.86% on the day, or $3.00.
