capitulation, page-123

"The vast amount of wealth is accumulated while sitting… while waiting patiently."

yes this is true, sometimes doing nothing while the markets aren't good is the best strategy, equally so sitting patiently on a winner is also a good thng to a certain point... Once the stock turns sour you have to be able to identify this and act on this and not let any positive biases interfere with your investment.

Ado has fallen almost 50% from it's highs I bet that many long termers if they knew this was going to happen would have happily sold out in the mid to high 20's.

"Don’t let any negativity in the market affect how you see individual stocks.
A negative bias will destroy your career."

This last quote is a little black and white because a trader or even investor
must remain flexible and open minded at all times, you simply can't just say I'm not selling because i thnk co xyz is so wonderful and it will be worth $1 b in the future. Whilst it's ok to think big and to visualize what may become of a company, when the technicals start diverging from your hypothesis then you should IMO never argue with the tape.
