Don’t the IFT limits prevent me from engaging in dollar cost averaging?
Dollar cost averaging is spending a fixed amount at regular intervals (e.g., monthly) on a particular investment regardless of share price. Dollar cost averaging is, by definition, not driven by the level of the market. A participant can most certainly employ a systematic investment plan, making IFTs every two weeks regardless of the performance of the market, just as dollar cost averaging is intended. In fact, this would essentially be the same frequency of dollar cost averaging into the TSP via deductions from biweekly paychecks.
