Always invest through SIPs in small-cap funds. Never invest a lump sum. Small-cap funds are more volatile. But don't stop your SIPs and wait for correction. It is very difficult to catch the bottom and the peak. Even if you get lucky with the correction, it will be extremely difficult for you to get in again. So, continue with your SIPs. They will help you average out your buying price and will improve your returns over time.
