I have money in both SMH and SMHX and down 17% and 22%. Is this something to buy and hold long term or do I really need to get out?

This is in my Roth IRA where I put my riskier plays. It's compiled of 3/4 SMH, SMHX, XLK, QQQM, FBTC and 1/4 VTI.

I like the semiconductor industry but feel I'm too focused on one sector. Is it too late to get out of these and can I generally expect them to recover and ride it out, or should I cut my losses and diversify? Ideally I have 15 years until early retirement.
