With increasing focus on sustainable and renewable energy, power grid infrastructure investment trusts (PGITs) have gained popularity among investors in recent years. As government policies and consumer demand drive the energy transition, investment in transmission and distribution networks is essential. Understanding the historical share price performance of major PGITs provides valuable insights for investors considering this sector.
PGITs own and operate power transmission and distribution assets, providing steady, contracted revenue streams. Key players like American Electric Power and Brookfield Infrastructure Partners operate large grid networks servicing millions of customers. Reviewing their long-term share price charts illustrates relatively low volatility compared to the broader market. This reflects the essential nature of their services and strong regulation providing income stability.
Investigating historical prices around key events also reveals how these trusts react to change. Periods of rising interest rates or inflation often pressure valuations, while new investments and acquisitions may boost share prices. Comparing performance across trusts highlights differences in geographic exposure, regulation, and management strategy. Ultimately, studying the historical trends helps set realistic return expectations and build conviction in PGITs as core portfolio holdings.

American Electric Power’s stable uptrend through various market environments
American Electric Power (AEP) operates regulated transmission and distribution assets delivering electricity to over 5 million customers across 11 states. As one of the largest U.S. grid operators, reviewing its long-term share price history provides a benchmark for the sector.
Since listing in 2001, AEP has shown a remarkably consistent long-term uptrend, rising over 350% in 20 years. This highlights the essential and stable nature of its business model and the broader sector. Periods of sharp market declines, like the 2008 financial crisis and 2020 COVID-19 crash, led to relatively muted pullbacks of 20-30%.
Meanwhile, low interest rate environments and growth initiatives fueled strong performance in the 2010s. Constructive state and federal regulatory decisions enabling reasonable returns boosted results. Overall, AEP has significantly outperformed the S&P 500 over the long run while exhibiting lower volatility.
Brookfield Infrastructure’s global diversification leads to different return profile
Brookfield Infrastructure Partners (BIP) operates an international portfolio of infrastructure assets across utilities, transport, energy and data infrastructure sectors. With assets in North/South America, Asia Pacific and Europe, its diversity provides valuable insights.
BIP’s share price has shown strong growth since listing in 2008, rising over 600% despite higher volatility. Its global assets exhibit greater sensitivity to macroeconomic conditions than domestic-focused counterparts like AEP. Periods of international expansion, like the early 2010s, fueled outperformance. Meanwhile, its broader mandate including transport and data infrastructure assets exposes it more to economic cycles.
For investors, BIP provides a way to access infrastructure beyond power grids. Its experienced management team has a strong track record of acquiring high-quality assets at attractive valuations. While individual investment results vary, the historical price action highlights the long-term return potential alongside the higher volatility.
Price reactions to changing interest rates and inflation expectations
As capital-intensive, yield-oriented sectors, infrastructure trusts exhibit sensitivity to interest rates and inflation. During periods of rising rates, increased financing costs may squeeze profit margins. Meanwhile, higher inflation can lead to increased expenses and impact valuations.
Reviewing performance during past rate hike cycles provides context on potential effects. For example, in the rising rate period of 2016-2019, PGITs like AEP and BIP saw muted single-digit returns. This lagged the S&P 500’s over 50% return, as higher yields offered competition for yield-focused investors. However, the PGITs exhibited lower drawdowns during market corrections.
More recently, 2022’s surge in inflation to multi-decade highs pressured valuations across yield sectors. But grid trusts held up relatively better than higher growth names exposed to demand destruction. Their essential assets and pricing power help offset rising costs. Overall, historical price action shows rising rates and inflation can impact short-term returns but not undermine long-term uptrends.
Acquisitions and growth initiatives provide share price catalysts
PGITs drive growth through acquisitions and organic investment in their networks. Major purchases and capital projects act as positive catalysts for share prices. For example, AEP’s 2015 purchase of the regulated utility APS boosted its presence in fast-growing Arizona. This strategic move expanded its footprint and supported a strong share price performance over the following years.
Similarly, BIP has consistently acquired infrastructure assets around the world. Its disciplined approach of acquiring high-quality assets at reasonable valuations has allowed consistent distribution growth. Major purchases like Australian gas pipelines in 2019 were well-received by investors.
Reviewing PGITs’ project backlogs and potential M&A pipelines help identify upcoming catalysts. Constructive regulatory decisions enabling reasonable returns on growth initiatives also support share prices over the long run. Ultimately, a history of successful acquisitions provides confidence in management’s capital allocation abilities.
In summary, reviewing PGIT share price history informs investment decisions. The sector exhibits relatively low volatility and consistent long-term uptrends, reflecting essential infrastructure with stable contracted cash flows. While periods of rising rates and inflation can create near-term headwinds, their underlying business stability supports long-term growth. Their consistent dividends, share price appreciation and lower risk profile make PGITs appealing core portfolio holdings for risk-averse investors.
