Is the stock market looking increasingly frothy given an uncertain economy – or is it just getting started on the next leg up? Only time will tell. What we do know is that, sooner or later, there . Whether it is next week or a decade away, only time will tell.

That lack of certainty about timing gives me an opportunity. I can use the time to prepare a plan of attack for what I should do as an investor when the crash does happen. After all, when the market goes down, it may be possible to than was the case just days before – and hopefully than will be the case in their long term future.

I am hoping to be able to pull together a spare £50K to invest during the next significant stock market downturn. Here is how I would try to turn it into a million pound portfolio over the long run. Getting ready, now My first move would be to make sure I was ready administratively.
