http://serezin-du-rhone.fr/pifpaxys/7124 Goldman Sachs has taken an interesting way to gauge the valuation of a company and its stock — buzz on social media. Its analysts used comments to warn on Tesla and its Model 3 sedan. Here is how they did it:

“They found that weekly posts about the Model 3 declined from an average of 3,900 a week last year to an average of 3,000 a week this year; posts with a positive skew have faded, they said.”
This is how PR measures public opinion to report back to clients. There is a caveat to this approach.  It is not statistically accurate because the sample is most likely not random but it can provide a broad indication of trends. Tesla ought to be concerned.
