no longer posts at Saul’s but Saul’s record is fantastic.
The difficulty is that late comers buy at the top. Valuation, specially DCF, are quite useless for hyper-growth stocks. A better approach is to understand the business model and concepts like the “S” curve and the Technology Adoption Life Cycle [TALC]. David Skok has great videos to understand the SaaS model.

What many investors fail to understand is that stock prices tend to be correlated to the general market and that different classes of stocks (value, growth, safety, etc.) tend to rotate as market favorites. If a growth stock does not have a long term future then it’s a risky investment. Growth stocks are also extremely volatile and if you don’t have the stomach or other body parts able to deal with it, then don’t invest in growth.
My suggestion, if you are not a growth investor don’t post at Saul’s and specially don’t preach brimstone and hellfire because you are going to be deleted for good reason.
I have been expecting a correction for quite a long while but it was only in early December that I finally decided to be on the sidelines except for my high conviction stocks and it’s not over yet. Better late than broke so I’m just watching the market play out.
