However, its effectiveness doesn’t confine us from exploring strategies which are less conventional, slightly sophisticated and suitable for an advanced investor in search of ideas to beat fellow investors. And that’s why we looked at whether the RBI’s repo rate can be a strong macro-economic signal to derive an “SIP strategy”.

Because the repo rate
