I am curious to see what you all think about closing positions when your investment thesis in a company appears broken.

I may be in the minority here, but I wouldn't say I like to close positions in these companies -- say $TDOC, $PTON, $LTCH, or $APPH for me.

I would love to have a "tidier" portfolio and put this money to work elsewhere, but most investors I admire have said that their biggest mistake was selling a stock too early.

In this weird sense, I have a kind of FOMO -- even when my investment thesis for a company isn't currently intact.

Mostly, this keeps me from thinking I'm smarter than I am -- getting too trigger-happy when I incorrectly feel a thesis is broken and selling right away -- and doing this too frequently.

Instead, I hold the position, stop adding, and let it run and rightsize itself to my portfolio, accumulating more data over a longer time frame.

Who is to say my investment thesis for the company was correct in the first place?
