<prompt> Human: Would now be a good time to invest in VANGUARDLS100? Ive been meaning to do it before the UK election but now theres a lot of volatility. Is that a good or a bad thing?  <response>: You cant time the market. There is never a known, confirmed good time or bad time to buy equities. The market has been on a bull run rising for about eight years now, which is pretty unprecedented, but there does not seem to be much standing in the way of further gains, but it could all burst tomorrow.. you get the idea.Volatility is in general not good for stock values -- the market hates uncertainty most of all -- but things change fast. Note that the night Trump was elected Dow futures were down 1000 as everyone panicked and thought he would destroy the western world, but by Christmas the market was up more than 10, so if you did not panic you made money.
