In the face of recent volatility and market sell-offs, investors often seek refuge in safe, time-tested stocks to protect their principal and grow their wealth. As the Nasdaq Composite experiences a significant correction, here are five unstoppable stocks to consider adding to your portfolio.

First on the list is AT&T (T 0.46%), a telecom titan that has weathered challenges and positioned itself for success in the current economic climate. Despite concerns over rising interest rates and allegations surrounding its cables, AT&T continues to upgrade its network to support 5G speeds, driving high-margin data consumption. The company's strong residential broadband segment, evidenced by 18 consecutive quarters of net additions, further solidifies its position. With an improved balance sheet and a safe 5.8% yield, AT&T offers stability during uncertain times.

AutoZone (AZO -1.17%), the auto parts service chain, presents an attractive opportunity during the Nasdaq sell-off. As drivers keep their vehicles for longer periods, the reliance on auto parts suppliers like AutoZone increases. The company's expansion of mega hubs and its robust share repurchase program further enhance its appeal. While its per-share price may be high, AutoZone has consistently delivered value to its shareholders.

For those seeking stability, NextEra Energy (NEE -0.10%) emerges as a top choice. As a leading electric utility company, NextEra offers a necessity service with highly predictable operating cash flow. What sets NextEra apart is its commitment to renewable energy, making it the global leader in wind and solar power capacity. With regulated operations and reduced generation costs, NextEra offers a steady investment opportunity.

White Mountains Insurance Group (WTM 0.09%) may not be a household name, but it has consistently rewarded patient shareholders. Operating in the insurance industry, which typically thrives in any economic climate, White Mountains offers municipal bond insurance, reinsurance, and property and casualty insurance. With a resemblance to Berkshire Hathaway, White Mountains' capital returns and its attractive valuation make it an enticing buy.

Last but not least, healthcare conglomerate Johnson & Johnson (JNJ 0.25%) presents a compelling option to protect principal and grow wealth during the Nasdaq sell-off. With a track record of dividend growth spanning 62 years and a stellar credit rating, J&J's consistent growth in adjusted operating earnings showcases the defensive nature of the healthcare industry. The company's stable leadership and focus on pharmaceuticals contribute to its growth potential.

While market volatility persists, these five unstoppable stocks offer resilient investment opportunities. As history demonstrates, long-term investors who remain patient tend to be rewarded. By choosing wisely and considering companies with proven track records and stable operations, investors can navigate challenging periods on Wall Street and potentially build wealth even amidst historic volatility.
