Hi there. Sorry, we were running some testing on our new Q&A and this was labelled as "answered" when it really wasn't, so I missed it!
WSP is a former Bull List stock here at Premium. We do really like the company but we did end up removing it due to valuation concerns. It's ran up even further in price now and has, for the most part, "grown" into its valuation.
The company is pretty much as expensive as it's ever been, and trading at 36x trailing cash flows, I'd say it's fully valued here. That said, I don't think there is any issues with buying a high-quality company like WSP at full value.
It will need to put up the strong double-digit growth it has been doing in order to justify this valuation. If there is a slowdown, it will no doubt face a drawdown in price.
If you don't mind paying a high valuation for a high quality company, I'd have no problem adding here. If you're a stickler for valuations, I'd be looking for a dip
