As the market continues to fluctuate, investors are seeking stable and high-yielding dividend stocks to add to their portfolios. While the S&P 500 index has a dividend yield of around 1.4%, there are several stocks within the healthcare sector that offer yields up to 6.3%. These stocks provide a steady income stream and the potential for capital appreciation. Here are three dividend stocks to consider:

1. AbbVie (ABBV)
* Dividend Yield: 3.7%
* AbbVie has a strong track record of increasing its dividend, having boosted its payout by a whopping 310% since its 2013 spinoff from Abbott Labs. The company has also carried on the dividend growth legacy it inherited from Abbott by boosting its payout every year.
* AbbVie invests heavily in research and development (R&D), spending about 15% of its revenue on it, which should drive future growth and support dividend sustainability.
* The company's shares have climbed this year, and are up 41.1% over the past 12 months.
2. Crown Castle (CCI)
* Dividend Yield: 6.1%
* Crown Castle has increased its dividend for 17 consecutive years, demonstrating a strong commitment to returning capital to shareholders. The company's stable and growing cash flow, driven by long-term leases with blue-chip tenants, supports its dividend sustainability.
* Crown Castle's shares have surged this year, up 27.3% year-to-date and 45.7% over the past 12 months.
3. Chevron (CVX)
* Dividend Yield: 4.1%
* Chevron has increased its dividend for 34 consecutive years, making it a Dividend Aristocrat. The company's strong financial position, with a robust balance sheet and consistent cash flow generation, supports its ability to maintain and grow its dividend in the long term.
* Chevron's shares have climbed this year, up 14.5% year-to-date and 28.7% over the past 12 months.



These three dividend stocks offer high yields and have demonstrated strong dividend growth and sustainability. However, it is essential to consider the risks associated with investing in dividend stocks, such as company-specific, industry-specific, and market-wide risks. By carefully evaluating these risks and diversifying your portfolio, you can better position yourself to weather market fluctuations and maintain a steady income stream from your dividend stock investments.
