Do you experience this, too?

My portfolio feels like it’s stuck because the investments never seem to move up together. Whenever some holdings are performing well, others are declining by about the same amount, offsetting any gains. Then, when the previously underperforming investments start to recover, the ones that were doing well begin to fall. As a result, the portfolio seems to move sideways instead of making meaningful progress, making it frustrating to see little overall growth despite constant movement within the individual investments.
