Mistiming risk is minimal or very short-lived in all debt funds (other than gilt funds) and in hybrid categories other than aggressive hybrid.

it is only in equity funds/hybrid aggressive funds that you can turn market volatility to your advantage, by investing on dips and lowering costs. In the absence of that volatility, you get no averaging benefit; in such funds, as long as your timeframe is right, it doesn’t matter whether you invest through SIP or lumpsum.
