Is Invest Grade Really Worth It?

I've been diving into the whole "Invest Grade" thing lately, and I’m curious what everyone else thinks about it. I keep hearing that it can be a solid indicator of quality for bonds and even stocks. But is it really a game changer, or does it just give a false sense of security? I’ve seen some folks swear by it when choosing investments, while others say it can be misleading, especially during market swings. Has anyone had any personal experiences related to Invest Grade ratings affecting their trading decisions? Would love to hear your thoughts or any tips if you’ve used it in your strategies!
