They've done well spotting scammy Chinese stocks, but most of them would be pretty obvious to us DD skeptics. For 25 years I've been advising investors to steer clear of anything Chinese. Did anyone here fall for Luckin Coffee?
MW CEO, Carson Block has been far less successful picking dogs among listed American stocks. He got American Tower dead wrong in 2013. That NYSE-listed REIT [AMT] has tripled since then along with paying regular and growing dividends.
For certain, Muddy Waters is expert at hyping its attacks, and often getting sued as a result. It's an "activist shorter" where most short sellers don't have that advantage. No one knows what its investment record is. MW doesn't release that data.
Muddy Waters doesn't short stocks simply because they're_"too_high." If you want to successfully short, first become expert at reading filings, and especially accounting-related footnotes, the excruciatingly boring stuff that requires knowledge and hard work. 99.9% of local penny flippers won't do that. Plus obvious short candidates -- Chinese junk for example -- can be very costly to borrow.
Never short a stock just because it pissed you off.
