I would personally vouch for investing in the NDQ. It is a good ETF covering a broad range of industries from Tech to Consumerables. I would personally allocate a large percentage (50% +) of my portfolio to that over the long term, as it would generate strong capital growth long term.

I bought last month around $37 and now it has cracked $40.

I personally want to invest more into US stocks on the NASDAQ, like Costco (COST). The growth on that stock has been phenomonal over the last few years.
