We can see that there was sudden rise in price of stock in early November creating gap.
This was filled after 2 months of consolidation.
PS:All gaps need not be filled however during reaction Gaps give reasonable idea of support/resistance.
Very good diversification of portfolio possible with Gold and DJI.
Everyone needs diversification of portfolio and having few good counters which are having negative beta helps de-risk and also avenue for investment when one counter turns bearish.
