@DavidGFool Real value certainly is with innovation. Apples results:

“…From the time Jobs launched it in 2007 to Cook’s first year at the helm, Apple’s revenue rose from $24 billion to $157 billion. In Cook’s first year, Apple sold 125 million iPhones. This year 260 million…”.

Success!

Stocks always go down faster than they go up.
And they always go up more than they go down!

The first explains the fear.
The second explains why optimism pays.

@drowsyinvestor @DavidGFool talks about this a lot. Just gotta buy and hold these types of high growth stocks as long as the fundimentals hold up. Pays off massively in the mid-long term.

I’ve called out “IMPACT INVESTING” before on @RBIPodcast—for its relative meaninglessness.

(Every investment has impact! Full stop.)

What people really mean, I think, is investing in people, places & problems historically underserved. My more awesome term:

Six games don’t make a baseball season. A handful of stock picks don’t make an investing career.

In 2008, the Phillies started 2–4 against lousy teams. They ended the year as World Series champions….
