As a retired stockbroker of 25 yrs, I never saw a good investment that didn't have flaws. So cvm has some, so what. If there wasn't something to worry about, it would not have any upside. From personal experience, the most perfect companies, the blue of the blue, when they get there, they are fully priced and often provided least growth. This has been true in my personal portfollio. It's this little guys that can beat the market. What they say about a bull market "having climb a wall of worry" is also true with individual stocks.
