Ok I understand your meaning now, but you are not saying the same thing as 7figures2commas' original comment.
The original comment said "You can't seriously look at the charts of companies like Netflix and Tesla and believe that this is the result of DCF analysis"
While your claim is that low interest rates automatically raise the value of companies, when computed with DCF analysis.
So I agree with you that low interest rates do increase stock prices, but it's not relevant to the discussion at hand, since the original post was clearly referring to mis-pricing of stocks. That also explains why I and, perhaps others, didn't understand your meaning. You were applying your own notion of how the Fed drives stock prices, not the one in the original post.
