US stock market has plunged this week as S&P 500, Dow Jones, and Nasdaq numbers were red. However, there are some Wall Street stocks that performed well. While, big tech stocks, specialty retailers, travel and energy companies took sizeable losses.

Companies that focus on food, health care and other necessities gained ground or held relatively stable. Many investors in search of safer places to put their money shifted their focus to companies that tend to hold up during economic slowdowns and recessions. They figured that Americans still need health care, basic necessities such as food, soap and toilet paper, and electricity to power their homes. Plus the occasional alcoholic or carbonated beverage.

Here are some companies that have managed to post gains or minimal losses for the week:

Food makers, grocery stores, and restaurants all expect to feel an impact from higher costs on imported products. Food, especially at grocery stores, is among the many expenses that can't be completely cut out of a budget and will likely be grudgingly absorbed by people.

Conagra, up 0.5%

General Mills, up 0.9%

Hormel Foods, up 1.3%

Electric, gas and other utility operators are also more resilient in shaky economies. It's another expense, much like gasoline for cars, that can't reasonably be cut out of a person's budget.

Exelon, up 1.4%

American Tower, up 2.1%

Consolidated Edison, up 0.5%

American Water Works, up 0.7%

Health care is among the safer sectors for investors. Hospital operators, insurance companies and other health-care related businesses are considered necessities.

Molina Healthcare, up 7.4%

Centene, up 3.2%

UnitedHealth Group, up 1.8%

Grocery stores and big retailers with substantial grocery sections are also considered resilient. Discount retailers often also benefit from consumers downshifting spending.

Kroger, up 0.7%

Dollar General, up 7.6%

TJX Companies, up 3.3%

Consumers that tend to cut back on eating and drinking out also shift some of that spending toward home consumption. Beer and soft-drink makers have warned that tariffs will hurt their bottom lines, but investors have been shifting some of their focus toward the bigger players.

Molson Coors Beverage, up 1%.
