I thought this was an interesting chart from Market Ear and GS. My takeaways are that it gives us some idea where pricing has been in an area that I find difficult to get a feel on ballpark valuations, since I mainly swim in the bigger end of town. However relevant for where much of the SM audience resides. What I see is where valuations can go under extreme stress, circa 2x sales in GFC and Euro crisis, about 2.5x sales under high stress eg 2018. Still some reasonable downside from here, possible if things tighten further.
Finally timing is critical, those clever enough or fortunate enough to get in around 2016/7 still ahead, (get sales growth + rerate) those entering in last couple of years, well a lot harder.
