Healthcare Sector Struggles, Yet These Yields Reaching 7% Might Still Be Viable
Healthcare Stocks Overview
- Market Performance: Healthcare stocks have remained stagnant since April, contrasting sharply with the S&P 500, which has surged by 27%. This stagnation has drawn the attention of contrarian investors looking for potential bargains or yield traps in the sector.
Key Healthcare Stocks
Omega Healthcare Investors (OHI): Offers a 6.4% yield and operates skilled nursing and assisted living facilities with a portfolio of 93,961 beds across over 1,000 properties. The company has shown recovery post-COVID, beating estimates for adjusted funds from operations (AFFO) and raising its full-year guidance. However, shares are trading at over 13 times next year's AFFO estimates, indicating a moderate valuation.
LTC Properties (LTC): With a 6.3% yield, LTC is transitioning some contracts to RIDEA-structured agreements, which could enhance growth potential. Currently, 7% of its enterprise value comes from this segment, with plans to double it by year-end.
Healthpeak Properties (DOC): This REIT has a 7.0% yield and a diverse portfolio including outpatient medical facilities and laboratories. The dividend was recently raised and converted to a monthly payout, but growth may be limited due to challenges in its life sciences segment.
Sila Realty Trust (SILA): A newer entrant with a 6.4% yield, SILA has delivered nearly 20% total returns since its IPO in June 2024. It has a solid financial position with long lease terms and a well-covered payout, although it reverted from a monthly to a quarterly dividend.
Pharmaceutical Sector Insights
Siga Technologies (SIGA): Offers a high yield of 7.1%, but is considered too concentrated as a single-drug company. Its future growth depends on diversification.
Bristol-Myers Squibb (BMY): A blue-chip pharmaceutical company with a market cap of nearly $100 billion and a 5.3% yield. Despite its diversified product line, BMY has underperformed, with a 25% decline in share price over five years. However, it recently beat earnings estimates and is forming strategic partnerships.
Pfizer (PFE): Currently yielding 6.9%, Pfizer has faced challenges, including the cancellation of a weight-loss drug trial and declining COVID-related sales. The company is targeting $7 billion in cost savings by 2027, but its dividend remains secure for now with a 55% payout ratio.
Investment Strategy
- Retirement Income Strategy: The article emphasizes the importance of generating income through dividends to avoid depleting capital in retirement. A proposed "No Withdrawal" portfolio could yield $40,000 annually from a $500,000 investment, highlighting the potential for high-yield investments to support retirement without touching the principal.
This analysis suggests that while healthcare stocks have been overlooked, there are opportunities for income-focused investors, particularly in REITs and select pharmaceutical companies.
