We have had 10 years of growth since the last recession (every gray line is a recession).
If you take into account the market corrections that we have seen this year as a sign, most people in finance will agree that there will be a correction in the next three years. It is far from speculation.

Edit: FYI I did not imply that market corrections == recession. The reason I put the image is to show that there hasn't been a recession in 10 years and that we are due for one. We have had a few market corrections this year, but no recession yet.
