Stock Exchange Investing

Assuming one cannot time the market and assuming that as long as you don’t invest at end of a long bull run (which is now true !) and with say 20 year investment horizon am considering monthly drip feed by direct debit into an equity unit trust

seems to me this is best way of investing into stock exchange right now i.e. monthly drip feed

are you looking to invest in the stock exchange for the sake of investing in the stock exchange? Cos that’s what it sounds like.

as part of a diversified portfolio
not sure i get your point but seems to be on a diversified basis there is value to be had and monthly drip feed limits exposure
