Did you take insurance, a term plan?
Small cap funds are volatile in nature, they may not give returns every year, they may even go down by 20% and stay there for some time, so should know what to do then, will you continue your SIP, or stop and wait for the small caps to start moving up?
How long will you continue investing, what is the time frame and return expectation, is there an end number, a corpus?
In investing a plan comes first, and then the investments.
