Gold just broke through to an all-time high around $4,600, and traders are eyeing the next major target: $5,000. That's sitting at a significant 4.618 Fibonacci extension level—not some random number, but a key resistance point that tends to matter in technical analysis. Whether gold rockets through or stalls depends on how aggressively buying continues. But if it does punch through to $5,000 quickly, that's when things get interesting for portfolio allocation. You'd likely see some meaningful capital rotations happening, with investors rebalancing between precious metals and other asset classes.
