Is it worth switching brokerages to chase a better deal?

Usually only if there's a real, lasting benefit — not just a one-time bonus. The big brokers already offer $0 commissions and no minimums, so the differences that justify a switch are things like noticeably higher cash sweep yields, a much better fund lineup, lower expense ratios on house funds, or consolidating scattered accounts into one place. Cash-transfer bonuses ($100–$2,500 for moving assets) can be worth capturing if you were going to move anyway, but chasing them repeatedly creates paperwork, tax-document clutter, and the risk of an account in transition during a market move. When you do switch, use an in-kind ACATS transfer so you don't sell and trigger taxes, and check for transfer-out fees. The best brokerage is often the one you'll actually stick with and keep funding consistently.
