It’s completely normal to feel uneasy when just seven companies are carrying the entire market. It makes everything feel more like a tech gamble than a real retirement plan. As of 2026, the "Big Seven" have not performed well, and other traditional industries are beginning to catch up and show some energy.
Since you don't have a long time to wait out a major crash, don't feel pressured to follow the hype. You might want to consider "Target-Date" funds or bonds within your 401(k). They are designed to move your money to safer investments as you get closer to needing it, so a quick drop in tech won't ruin your savings.
